一句话结论:这场 65 分钟的对谈没有得出「RSI 临近」或「威胁夸大」的结论——它把争论拆到了可验证的颗粒度:Codex 支出翻倍说明什么、研究生产力 10 倍的口径怎么定、中美差距用什么方法测、蒸馏到底解释了多少。
这场对谈发生在「AI 正在加速 AI 研究」(递归自我改进,RSI)叙事重新升温的当口:OpenAI 与 Anthropic 先后发文称内部已观察到 AI 显著加速研发。主持人 Nathan Lambert 对此偏怀疑——他认为可测量的环节会先被拉升、战略决策与「领域整体理解」难以同等加速;嘉宾 JS Denain 则是「温和加速派」:他不像实验室那样宣称临界点在即,但认为公开证据叠加先验论证已足以严肃对待这一动态。两人最重要的分歧有四:(1) 中美模型差距到底是两三个季度(Lambert)还是 4-8 个月(Denain),蒸馏(distillation)是不是主因——Denain 本场明确「更新」为蒸馏很重要,Lambert 则坚持算力差距、组织与人的因素足以解释;(2) 机器人驱动的实体工业爆炸何时发生,Lambert 认为更像自动驾驶的漫长长尾,Denain 认为不该低估供给侧弹性;(3) 「AI 研究 10 倍提速」究竟指个人效率、公司产出还是领域理解速度——层级不同,结论完全不同;(4) 开放与封闭模型哪个滥用风险更大。共识同样清晰:能力分布高度锯齿化(jaggedness),安全讨论必须落到具体威胁建模(threat modeling),而非泛泛而谈。
1. 测量与叙事的落差:双方都承认公开证据(Codex 支出月翻倍等)不足以证明「临界点在即」。分歧在证据的含金量——Denain 认为公开证据+先验已足以严肃跟踪,Lambert 强调区分「实质性证据」与「实验室文化氛围的自我强化」。
2. 「10 倍」的语义分层:本场最重要的概念澄清——个人研究员的任务循环提速、公司整体产出、领域「完整理解速度」是三个不同层级的量;算力等外部瓶颈决定个人提升能否传导为公司/领域提升。这直接决定 RSI 叙事是「研究效率革命」还是「智能爆炸」。
3. 可测量性决定加速形状:Lambert 的核心论点——凡是可测量的(推理效率、编码、爬山型任务)会先被拉爆然后饱和;不可测量的(化学突破、开放领域科学)才是真正的不确定区。Denain 以「可验证任务是更大可验证任务的子集」回应,暗示这条边界会随时间外移。
1. 两条 S 曲线之争:Lambert 用自动驾驶的历史警告「长尾场景+建厂链条」会把实体世界爆炸拖到十年尺度;Denain 用数据中心扩建与「供给弹性」反驳「建厂慢」论——若需求与能力同时到位,资本会以惊人速度涌入。
2. 锯齿性作为桥:Denain 把「锯齿状能力分布」用到物理世界:不需要全人形灵巧,只需要在「机器人优先」的受限环境里够用,某些行业就能先爆发。这弱化了「机器人能力全面达标」的门槛。
3. 对安全讨论的含义:Denain 提出「造成灾难的最小能力集」问题(核密码 vs 通用机器人灵巧手),把末日威胁建模从「能力大小」转向「能力组合」,这是本场对 x-risk 讨论最具体的落地。
1. 测量口径决定答案:发布到发布 vs 建成到建成、前瞻插值 vs 阶梯比较,会给出不同的差距;4-8 个月的区间宽度主要来自方法学不确定性。
2. 反直觉的实证结果:Epoch 的内部分析显示「基准污染/过拟合」对差距的解释力不显著——中国模型的成绩并非刷榜假象;但 ECI 仍可能因「不可测能力」(产品化、服务广度)低估美国领先。
3. 行业含义:若差距真在两个季度内,开源权重模型的商用格局与算力出口管制辩论的紧迫性都会被改写;这也是后面蒸馏之争的伏笔。
1. 本场最大的观点更新:Denain 把蒸馏从中性更新为「大因素」(Stolen Thoughts 论文 + Claude 路由 + SFT 初始化论三重证据),Lambert 则坚持「低垂果实+风格不可简单复制」论。这场辩论的实证裁决将直接影响出口管制与开源政策的走向。
2. 「能力滞后 < 资本滞后」之谜:这是理解中美 AI 竞争的核心问题。候选答案包括要素结构(人/数据滞后小于算力)、RL 环境市场的「研发算力折价转存」、四分钟一英里式的概念验证效应、以及组织短视野。蒸馏只是其中一个候选变量。
3. 政策含义:若蒸馏被证实是主因,「限制 API 滥用」就从防越狱问题升级为地缘技术管制问题;若算力与组织才是主因,出口管制的杠杆点则完全不同。
1. 招聘数据=低成本的产业情报:在财报与官方数据缺位的中国 AI 产业,岗位结构(销售 vs 研究 vs 基建)是少数可系统观测的公开信号——智谱的 B2B 化、MiniMax 的国际化由此显形,「自建数据中心」这类事实也从岗位地域分布中泄露。
2. AI 加速情报工作自身的边界:Denain 划出清楚的分界——分类与追踪可自动化,「什么有趣」的判断仍靠人。这本身就是「锯齿状能力分布」的一个微型例证。
3. 数据要素的可观测性危机:算力有数据中心与 NVIDIA 财报可查,数据市场几乎完全暗箱;若「中国数据市场爆炸」属实,出口管制辩论的重心将从 GPU 转向数据采购与人才组织方式。
1. 风险从「模型层」转移到「服务层」:Lambert 的核心论断——API 托管即泄漏,蒸馏式能力提取无法根除;安全投入的重心应从「权重对齐」扩展到「服务基础设施」与推理侧监控。
2. 「开放 vs 封闭」的答案取决于威胁模型:双方共同把一个意识形态问题改写为方法论问题——先明确「谁、想干什么、要多快」,再比较开放自托管与越狱封闭模型的成本。泛泛的「开源更危险/更安全」之争在此失效。
3. 冷静的现实基线:没有雪崩,但有常态化的低烈度事故(Hugging Face 式事件、neocloud、失控开源智能体);保险费率与披露机制是少数可观测的安全指标。
1. 研究议程的三个来源:重大问题(好奇心驱动)、公众误解(纠错驱动)、泄露在外的证据(机会驱动)——第三类解释了 Epoch 方法论上的独特生态位:把别人不在意的公开痕迹(招聘、数据中心卫星图)变成定量证据。
2. 观测性是流动的:同一指标会从「读论文可得」(训练算力)滑向「战略隐藏」(未来的数据中心、Astra 级模型);Epoch 的价值部分在于在窗口关闭之前建立基线与追踪方法。
1. 后训练是「竞标制联邦系统」:Denain 的模型——领域子团队以真金白银购买的评测为北极星、竞标数据与超参数进入一次大 RL run——解释了为何前沿配方难以被开源三阶段流水线复刻,也解释了「评测为什么昂贵且稀缺」。
2. 配方复杂度=进展速度的隐藏变量:Lambert 指出若前沿真实配方是「简单循环」(mid-training + 大 RL),则进步会更快;专家联邦+合并+MOPD 的复杂度本身就是瓶颈。这对判断「开源追赶速度」与「蒸馏传闻的来源」同样适用。
3. 风向判断:Denain 感知业界正从「多专家+MOPD+海量 checkpoint」收敛向「一次大 run」,与第四章「mid-training/蒸馏重要性上升」的传闻互相印证——两条线索在本章收束。
主题 | Lambert 立场 | Denain 立场 | 一句话含义 |
|---|---|---|---|
RSI 临近度 | 公开证据不足以支持临界点叙事;警惕实验室文化放大恐惧 | 证据不超强,但公开证据+先验已足以严肃跟踪;内部 KPI(算力乘数)才是早期预警 | 两人都不是末日派,分歧在证据的「含金量」 |
AI 研究 10 倍提速 | 想法→实验循环会 10 倍,但领域「完整理解速度」未必 | 中位数研究员可 10 倍,但算力等瓶颈阻止其传导为公司整体 10 倍 | 「生产力」的层级定义决定 RSI 是效率革命还是智能爆炸 |
机器人工业爆炸 | 更像自动驾驶曲线;数十年尺度,非 2-5 年 | 不低估供给弹性;机器人优先工厂+锯齿能力可先在局部行业爆发 | 实体世界是加速情景的最大折扣项,也是最大变数 |
中美模型差距 | 2-4 个月(Kimi K3、GLM 5.2 逼近) | 4-8 个月(发布对发布),2 个月像过拟合 | 口径之争背后是对「不可测能力」的不同权重 |
蒸馏的作用 | 作用有限;低垂果实多,差距无需蒸馏解释 | 已更新为「大因素」:Stolen Thoughts、Claude 路由、SFT 初始化 | 本场最大观点分歧,直接关系出口管制逻辑 |
开放 vs 封闭模型风险 | 服务层泄漏是主通道;托管 API 即假定能力可被提取 | 取决于威胁建模;开放模型会在「防护最弱处」先被攻破 | 把意识形态之争改写为方法论问题 |
ECI 加速 5 倍 | 可能出现但属 Goodhart,可测量指标先涨后饱和 | 很可能出现,因为它是公司明确的 KPI | 指标暴涨≠真实能力同幅暴涨,评测口径将成主战场 |
安全现状 | 网络安全已入「新常态」,无台阶式恶化 | 预期 Hugging Face 式事故常态化,neocloud 与失控开源智能体增多 | 冷静基线:混乱但非雪崩,最大的防线是作恶者稀缺 |

把 65 分钟压成三句话:第一,RSI 之争的本质是「研发环节中哪些可被 AI 压缩」的测量问题——双方都同意战略决策与理解型研究最难自动化,这部分决定了反馈循环不会一夜启动。第二,中美 4-8 个月的差距与数年的资本差距之间的缺口,目前由「蒸馏 + 环境转售 + 跟进式创新 + 苦功效率」共同填补——成因比数字更重要,因为它决定差距走向。第三,安全议题的成熟度最高:没有末日清单,只有「防护最弱处先被攻破」的方法论问题。对医疗器械这类强监管行业的映射也很直接:AGI 时间线争论不会改变「模型输出必须可验证、可审计」的合规底座,而「锯齿状能力分布」恰恰提示——先在窄而可验证的环节(文档生成、数据整理、审查辅助)落地,比等待通用能力更有性价比。

Nathan Lambert · 00:00:00
I’m here with JS Denain, who is a senior researcher at Epoch AI. He leads the insights team. He is one of the people who I feel like I get the best feedback on my writing from, whether it’s from US-China AI capabilities, now RSI. And I just wanted to open this discussion and honestly go deeper with him, trying to understand how he thinks about these various things. And I think you have a very useful, moderate point of view, which I feel like you’re probably a step further into what would be called faster scenarios for AI progress. But let’s get into this, and it’s like, what measurements do you think OpenAI and Anthropic are seeing when we get all these proclamations on RSI happening very imminently?
JS Denain · 00:00:47
Yeah. I think, so there’s the measurements they’ve published, right? So, OpenAI and Anthropic both had blog posts, I mean, Anthropic two at least, on the effect AI has on accelerating AI progress. I think at least the things they publish, I don’t think are super strong evidence of imminent self-sustaining acceleration AI capabilities, or full automation of the job of AI researcher. But I think the kinds of things we see are, I think probably the most striking thing I saw in the OpenAI blog post was increasing usage of AI systems in model deployment, like the increase in spending on Codex that we saw. And it’s kind of unclear how exactly to interpret this, because maybe it’s a measurement artifact where they’re only looking at Codex, but in fact, there was a bunch of ChatGPT usage before from the researchers. But overall, that plot, for example, just shows a 2X a month increase in Codex spending by researchers, and that does seem to me to be some evidence of they’re getting a lot of value out of this probably. I don’t think this is strong evidence that in six months we have a software intelligence explosion.
对。我想,他们已经公布了部分测量数据,对吧?OpenAI 和 Anthropic 都发过博客文章——我是说,Anthropic 至少发过两篇——讨论 AI 对加速 AI 进展的影响。我认为,至少就他们公开发表的内容而言,并不构成「自我维持的加速型 AI 能力」或「AI 研究员工作完全自动化」即将到来的非常强的证据。但我认为我们看到的那类信号里,OpenAI 那篇博客中最让我印象深刻的,是 AI 系统在模型部署中的使用量在增长,比如我们看到的 Codex 支出上升。不过这到底该怎么解读还不太清楚,因为这可能只是测量上的假象——他们只统计了 Codex,而事实上研究员们之前一直大量使用 ChatGPT。但总体而言,比如那张图显示研究员在 Codex 上的支出每月翻倍(2X/月),在我看来这确实算是某种证据,说明他们大概率从中获得了很大价值。但我不认为这是「六个月内就会出现软件智能爆炸」的有力证据。
Nathan Lambert · 00:01:57
Do you think this is the same? So, what is the information they have internally relative to what we have? And this is obviously hypothetical. We don’t have this internal information. Because I get the sense that a lot of people are more scared in their updates from the labs than the information we have. And I try to take this very seriously of, what will they be seeing that is making the acceleration of risk comments go faster, and how much of this is material evidence versus how cultures evolve over time? And I’m much more interested in evidence.
你觉得这是一回事吗?也就是说,他们内部掌握的信息相对于我们所能看到的,是什么情况?这显然是个假设性问题,我们并没有这些内部信息。因为我的感觉是,很多人从实验室得到的更新,比我们手头的公开信息更让他们恐惧。我非常认真地对待这个问题:他们到底会看到什么,才使得关于加速风险的言论变得更急迫?这其中有多少是实质性证据,又有多少只是组织文化随时间的演变?我对证据更感兴趣。
JS Denain · 00:02:29
Yeah. So two things. I think, first of all, I guess I don’t think, I don’t know, right? I don’t have full information here. I don’t currently think that either there’s some specific thing that people at OpenAI or Anthropic are seeing right now that we don’t have access to that warrants being way more freaked out about this. I also don’t think that... I think the public evidence we have right now, more general on AI progress and just a priori case for this being an important dynamic, I think is enough. I think to care about this particular dynamic of AI accelerating AI progress, that being a big deal and worth tracking. And then it’s kind of unclear what the urgency is of when the feedback loop really kicks in. So, basically on the what is there on the inside that people have access to, I could give examples of kinds of metrics, right, they could be looking at. It’s plausible that we have access to the capabilities of AI systems, but internal teams have their KPIs, and maybe they’re seeing compute multipliers in the pre-training team or other kinds of metrics that people are tracking going crazy. And then the combination of this plus some intuitions of how the different outputs of different teams combine yields a prediction on the trend in actual performance of the end AI systems. So that could be an early warning sign. It’s unclear to me that the recent discourse we’ve seen is evidence of things going crazy on those metrics.
对。有两点。首先,我想说我并不知道,对吧?我在这里并没有完整信息。我目前不认为 OpenAI 或 Anthropic 的人现在看到了某种我们接触不到的具体东西,值得大家为此大大加剧恐慌。我同样也不认为……我认为我们目前掌握的公开证据——关于 AI 进展的更普遍的证据,以及「这是一个重要动态」的先验论证——我认为已经足够了。足够支撑我们认真对待「AI 加速 AI 进展」这个动态,把它当成一件大事、一件值得追踪的事。至于反馈循环真正启动的紧迫性何时到来,则还不太清楚。所以,关于「内部的人到底能看到什么」,我可以举一些他们可能在看的指标类型:有可能外部能看到 AI 系统的能力水平,但内部团队有自己的 KPI,也许他们看到预训练团队的算力乘数(compute multiplier)或其他正在追踪的指标在疯涨。再加上对「不同团队的不同产出如何组合」的一些直觉,就能对最终 AI 系统实际性能的趋势做出预测。这可能是一个早期预警信号。但我不太确定,我们最近看到的那些讨论,是否就是这些指标已经失控的证据。
Nathan Lambert · 00:04:09
And how do you think of the link between RSI and existential risk? So I would posit that you agree. I think that there are very real risks of AI, and I’m curious on how you think these, what I would describe as very, very early measurements change anything on the scope of risk. Because I don’t think if you had asked people six months ago, it would be as immediate to x-risk among people are very reasonable. I think there’s more people that are reasonable talking about x-risk again, which was a little surprising to me.
那你怎么看 RSI 与存在性风险(x-risk)之间的联系?我想先设定一个前提:你同意 AI 存在非常真实的风险。我很好奇,你认为这些在我看来非常、非常早期的测量数据,会如何改变风险的量级?因为我觉得,如果六个月前问那些非常理性的人,x-risk 不会像现在这样被当成迫在眉睫的事。现在又有更多理性的人重新开始谈论 x-risk,这让我有点意外。
JS Denain · 00:04:43
Yeah. So, okay, my sense is something like... So personally, I feel very uncertain about this, but I do feel, yeah, basically bought into there’s, I know Evan Hubinger was like, at least 10% of x-risk within I don’t know what timeframe. I think I’m like, yeah, I know, and this seems pretty reasonable over a decade-long timeframe. I just feel extremely uncertain about it, but I’m definitely very worried about this. Now, why am I worried about this, and where do I think the disagreements come from? And then how do I relate this to the early sense of RSI? My sense, I’m kind of a capabilities theory of everything person. I think, and I think some people disagree here, but I really think that principal component of disagreement between everyone is how huge do the capabilities get, how soon, of AI systems? And I sort of agree that there’s other factors that come in play for how big your economic growth gets, also depend on the diffusion you get. And you could possibly you could think that capabilities are going to get crazy, but the AI system’s going to be just aligned and benign and stuff, and so there’s no huge risk. But my sense is concretely, when I look at the main kinds of disagreements between people, most of the people who I see who are very skeptical of those most extreme scenarios... I think just expect capabilities to not be as huge or as I think folks who are—
对。嗯,我的感觉大致是……就个人而言,我对这件事非常不确定,但我确实基本接受了这样的观点:我知道 Evan Hubinger 说过,在某个时间框架内存在至少 10% 的存在性风险。我想我的态度是:对,在十年左右的时间尺度上,这个估计看起来相当合理。我对此感到极度不确定,但我确实非常担心。那么,我为什么会担心?我认为分歧从何而来?我又如何把这一切与 RSI 的早期迹象联系起来?我的感觉是,我算是一个「能力决定一切」理论的人。我认为——有些人可能不同意——但我真的认为,所有人之间分歧的主成分是:AI 系统的能力会变得多大、多快?我某种程度上也同意,经济增长最终有多大还取决于其他因素,也取决于技术扩散的速度。你当然可以认为能力会变得疯狂,但 AI 系统是对齐的、良性的,所以没有巨大风险。但具体来说,当我观察人们之间主要的分歧类型时,我看到的大多数对那些极端情景非常怀疑的人……我认为他们只是预期能力不会像我设想的那样巨大,或者说,我认为那些人——
Nathan Lambert · 00:06:18
What does being a capabilities maximalist look like in a few years? Because I think I’m probably on the skeptical side, so please continue.
一个「能力最大化主义者」在几年后会是什么样子?因为我猜我大概站在怀疑派那边。请继续。
JS Denain · 00:06:28
I think it looks, for example, something like the AI 2027 scenario, right? I think it looks like the mechanism for this is AI is automating the AI research process, I think, and that’s a reason to pay attention to it. But in terms of effect on the real world, I think it’s like massive progress on robotics. I think a huge industrial explosion, AI systems are just managing factories. You have this kind of self-sustaining economy that just is able to make a large scientific progress much faster than you would have expected. And so I think concretely, the kinds of disagreements I would expect are on, yeah, if you have AI systems that are both very intelligent in the book smart sense, but also have been trained to have more affordances and use them astutely, have been trained to kind of manage projects in efficient ways and stuff like that. How big are the real-world bottlenecks to making very fast R&D progress or getting hard power over humans?
我认为它看起来大概就像 AI 2027 那样的情景,对吧?我认为其机制是:AI 在自动化 AI 研究流程本身,这是值得关注的理由。但就其对现实世界的影响而言,我认为会是机器人技术的巨大进步、一场巨大的工业爆炸,AI 系统直接管理工厂。你会看到一种自我维持的经济体,它能够以远超预期的速度取得重大科学进展。所以具体来说,我预期的分歧点在于:如果你拥有的 AI 系统不仅在「书本智能」意义上非常聪明,而且经过训练拥有更多的行动能力(affordances)并能聪明地运用它们,经过训练能高效地管理项目等等——那么,实现极快研发进展、或对人类获得硬实力(hard power)的现实世界瓶颈到底还有多大?
Nathan Lambert · 00:07:26
Yeah. Can we go into some of these in detail? Did you listen to the Dwarkesh podcast with Charlie, Beren, and John?
对。我们能详细聊聊其中一些吗?你听过 Dwarkesh 与 Charlie、Beren 和 John 的那期播客吗?
JS Denain · 00:07:32
Yes. Yeah.
听过。对。
Nathan Lambert · 00:07:33
Yeah, because they had at the end, they had this section on various capability levels and timelines for getting them. And I feel like I agreed with most... I was very in agreement on the distribution they had up to this, and then was surprised by the timelines. And one of them was the 10X productivity for the AI researchers. And I think Beren and John were faster than I think. And my kind of statement is that I think the cycle from of having an idea and doing the experimentation to test it, I agree will be 10X faster very soon. But I don’t necessarily agree that I would say that AI researchers will be 10X more productive in net, which I would describe as the pace of the field’s complete understanding. And understanding is a different axis from just continuing to scale models. I think that’s one of my core confusions on the AI research side. So I’m just kind of curious how you think about this type of thing and how you might specify a 10X improvement in AI research into subcategories.
好,因为他们在最后有一段关于各种能力等级以及达到这些等级所需时间线的内容。我觉得我同意其中大部分……对他们给出的前半部分分布我非常认同,但对时间线感到意外。其中之一就是 AI 研究员生产力提升 10 倍。我认为 Beren 和 John 给出的时间比我预期的更快。我的说法是:我认为「产生想法、做实验验证」这个循环很快就会快 10 倍,这一点我同意。但我不一定同意「AI 研究员的净生产力会提高 10 倍」——我会把后者描述为「整个领域完整理解的推进速度」。而「理解」与「继续扩大模型规模」是不同的维度。这是我在 AI 研究问题上最核心的困惑之一。所以我很好奇你怎么看待这类问题,以及你会如何把「AI 研究效率提升 10 倍」拆解成子类别。
JS Denain · 00:08:37
Yeah. So maybe there’s a scale you could have here, which is the end thing that you might care about is how much faster is AI research overall? Or how much faster is Anthropic’s overall output? And then Anthropic as a company is producing some things, and it’s doing in one year what it would have taken it 10 years to do. And that’s pretty different from individual researcher productivities, where I think you could... So if most of what AI researchers right now are doing is this loop that you were describing, then it’s possible that you get a 10X productivity improvement for the median researcher based on the tasks they’re doing right now. But first of all, that doesn’t mean you get a 10X productivity improvement for all researchers. And even if you did, right, there’s other bottlenecks that hit such that that needn’t convert into a 10X productivity improvement for Anthropic as a whole, right? You could have all the researchers be 10X more productive, but because of compute or other things, the company itself still doesn’t move as fast.
对。也许这里可以有一个层级:你最关心的最终问题是「AI 研究整体上快了多少」,或者「Anthropic 的整体产出快了多少」。Anthropic 作为公司产出一些东西,它用一年时间完成了原本需要十年才能完成的事情。这和单个研究员的生产力很不一样。如果现在 AI 研究员做的大部分就是你刚才描述的那个循环,那么基于他们当前正在做的任务,普通研究员确实有可能获得 10 倍的生产力提升。但首先,这不意味着所有研究员都能获得 10 倍提升。而且即便如此,还有其他瓶颈会起作用,使得它不一定转化为 Anthropic 整体 10 倍的生产力提升,对吧?你可以让所有研究员的生产力都提高 10 倍,但由于算力或其他因素,公司整体的速度依然没有快起来。
Nathan Lambert · 00:09:38
I think an analogy I have is, I think that junior PhD students will be 10X as productive, but from the advisor’s perspective, their research agenda will not proceed 10X as fast. And it’s like to the extent that that contributes to Anthropic’s progress is another hard thing to jump on AI capabilities, where I think that listening to the Noam podcast. This is me, I’m just thinking, was thinking about this when writing about this, is there’s such an amount of inference compute coming online, and I think Dwarkesh highlights this very well, that it’s very hard for me to disambiguate massive speed-up in AI research from the fact that we have way more compute and can now much more effectively spend it on related problems. And I think we’re going to get all of this at once.
我有一个类比:我认为初级博士生会变得高效 10 倍,但从导师的视角看,他们的研究议程并不会因此快 10 倍。至于这能在多大程度上转化为 Anthropic 的进展,又是一个很难跨越到 AI 能力问题上的难点。我在听 Noam 那期播客时——这只是我本人在写作时的思考——有个感受:即将上线的推理算力规模巨大,Dwarkesh 对此强调得非常好,以至于我很难把「AI 研究大幅提速」与「我们的算力多得多、现在能更有效地把它花在相关问题上」区分开。而且我认为这些事会同时发生。
JS Denain · 00:10:27
Yeah. So definitely I think this question of... So when you look at the OpenAI blog post they had on their acceleration, right, they do point out huge surge in Codex spending from researchers. Interestingly, actually, Codex spending in other parts of the company kind of had a huge surge in the spring and then kind of plateaued in the summer. But for researchers or the data team or engineers, it keeps growing, even accelerates sometimes. And so they point this out, and then they try to look at where there was an increase, which kinds of tasks had an increase in usage. And a lot of them are engineering tasks. There’s an increase in troubleshooting tasks. But they definitely point out that for a lot of the high-level strategic decision-making, they both anecdotally and also when they look at sessions, don’t seem to find a huge uplift in making better compute allocation decisions or deciding on research directions. And so to me, that’s pretty similar to the PI case. And so I think there’s a first question, which is, how much of an improvement... Imagine you just didn’t get that much AI uplift on that component of AI research, but the rest of AI research really went crazy. Then how much faster do things go? And the separate question is, I don’t know, how hard is this strategic decision-making? Can’t you just have a bit longer horizon RL? Or maybe you can bet on decent transfer from other fields where those kind of decisions are important, and then you do actually get that kind of uplift at the end.
对。所以这个问题确实是……当你看 OpenAI 那篇关于自身加速的博客时,他们确实指出了研究员在 Codex 支出上的巨大激增。有意思的是,实际上公司其他部门的 Codex 支出在春季出现了巨大激增,然后在夏季趋于平缓。但对研究员、数据团队或工程师来说,支出持续增长,有时甚至还在加速。所以他们指出了这一点,接着试图观察增长出现在哪里、哪类任务的使用量在增加。其中很多是工程类任务,故障排查类任务有所增加。但他们确实指出,对于大量高层战略决策,无论是轶事证据还是他们查看会话记录,似乎都没有发现「在算力分配决策或研究方向选择上做得更好」的大幅提升。在我看来,这与 PI 的情况非常类似。所以我认为第一个问题是:想象一下,如果 AI 在「战略决策」这个环节上没有带来太多提升,但 AI 研究的其他部分真的突飞猛进,那么整体到底会快多少?另一个独立的问题是:这种战略决策到底有多难?难道不能就用时程更长的强化学习(RL)吗?或者也许可以押注其他领域——在那些领域这类决策很重要——能提供不错的迁移能力,这样最终你确实能获得那种提升。
Nathan Lambert · 00:11:59
I think part of my intuition is that science will look so fundamentally different that it’s almost hard to put a number on it. And it’s the pre and post-AI era, and we’re just in the rapid transition to what is a new method, new way of doing science, because I think all the conferences are ready to burn down and struggle through the next few years. I hope that they collectively figure out a way to like add AI oversight into reviewing and things that are scalable, because they have so many slop papers that they need this type of gate. So I don’t really know. And I think on the capability side, I’m like, what an AI progress is like clearly translated into new capabilities. There are two things. One is like pre-training scaling laws. Our loss is proportional to like an exponential increase in compute. And on the research side, what we are doing is we’re shifting the line so that it has a better offset and potentially a better slope. And then on the other side is the RL environments, and I think the RL environments we’re building now are very comparable to valuable work. So I expect the AI models to get much, much better at like knowledge work that can be scoped. But I don’t know if we have a good process for like churning out an order of magnitude harder environments, which would be closer to like cure cancer, solve these open math problems. I think math is a case that we could talk about. But that’s kind of like, I think there are unknowns on scaling the like raw intelligence more than efficiency. So I’m very optimistic in scaling efficiency.
我觉得我的一部分直觉是:科学将呈现出根本不同的面貌,以至于几乎难以用一个数字来衡量。这是「前 AI 时代」与「后 AI 时代」的分别,而我们正处于向全新科学方法的快速过渡之中——因为我觉得各个学术会议都已准备好被烧毁、挣扎着熬过接下来几年。我希望它们能集体想出办法,把 AI 监督纳入审稿等可扩展的环节,因为低质量(slop)论文实在太多,它们需要这种把关闸门。所以我说不好。在能力方面,我的想法是:AI 进展显然要转化为新能力才作数。这有两件事。一是预训练缩放律(scaling laws):损失与算力的指数增长成比例地下降。而在研究侧,我们所做的是移动这条线,让它有更好的截距,甚至可能有更好的斜率。另一边是 RL 环境,我认为我们现在构建的 RL 环境已经非常接近有价值的工作了。所以我预期 AI 模型在「可以被清晰界定范围的知识工作」上会变得好得多、好得多。但我不知道我们是否有一个好的流程,能够持续产出难度高一个量级的环境——那种更接近「治愈癌症、解决这些公开数学难题」的东西。数学也许是个可以聊的案例。但总的来说,我认为在「扩展原始智能」上还有未知,而不仅仅是扩展效率。我对扩展效率非常乐观。
JS Denain · 00:13:29
Yeah. I agree that like in some sense, right, like inference efficiency is like a very like hill-climbing task. It’s like pretty well-scoped. And yeah, so I mean, it’s already something that has very, very fast trends, but I could imagine those trends. Yeah, I imagine those trends will go even faster. It seems really like the kind of... I mean, indeed, we have evidence from OpenAI, right? Like, saving on like serving costs, et cetera, through like building better kernels and like if you’re new to this. They don’t give that many details, but that’s already happening. One thing I’m curious about actually in your case is like, so here’s one way of defining like Anthropic, for example, like accelerates overall, which is you could look at the like ECI trend in like, the ECI of the best Anthropic quality point in time. And you can like look at the current trend line and you can ask the question, like over the next year, will we see a 5X acceleration? Like, will the slope be like 5X larger than it was, say, in like 2025? And I think it’s like pretty likely we see like a huge increase in this because it is like kind of a legible like KPI that like, I mean, it’s not literally KPI, but it is a KPI that like the company is aiming for, modulo like safety considerations, et cetera. And I’m curious about whether you think it’s very unlikely we get this or whether it’s more like we might get this, but like if we do get this, it’s mostly that like ECI has been Goodharted as a metric and like the implications for like real-world capabilities aren’t that huge.
对。我同意,从某种意义上说,推理效率是一个非常典型的爬山式(hill-climbing)任务,它的范围界定得相当好。而且它本来就已经有非常、非常快的趋势,我可以想象这些趋势还会更快。这看起来确实像那种……我是说,我们确实有来自 OpenAI 的证据,对吧?比如通过构建更好的内核(kernel)等手段来节省服务成本等等。他们没有给出太多细节,但这已经在发生了。关于你的立场,我实际好奇的一点是:这里有一种定义「Anthropic 整体在加速」的方法——你可以看「Anthropic 各时点最佳质量模型」的 ECI(Epoch Capabilities Index)趋势。你可以看当前趋势线,然后问:未来一年我们会看到 5 倍的加速吗?斜率会比比如 2025 年大 5 倍吗?我认为我们很可能会看到巨大的增长,因为这算是一个清晰可读的 KPI——虽然不严格是 KPI,但确实是公司在瞄准的指标(当然要扣除安全等方面的考量)。我好奇的是:你认为这种情况出现的概率很低,还是说更像是「可能会发生,但即使发生,也主要是 ECI 作为指标被古德哈特定律化(Goodharted)了,对现实世界能力的启示其实没那么大」?
Nathan Lambert · 00:15:03
I wouldn’t be surprised if we got this, but I think that it’s going to be like we’re on a slope and then we could get an uptick in slope of hill climbing, but then we like saturate what we know how to hill climb and then it goes to be lower. So it’s like all the things that we could measure I think are going to be getting pulled up very quickly by being measurable. And then we’re in the domain of like, how do we measure it? Because I think, like I talk to people that are trying... Like evals are so expensive to build now, and I do think that evaluations are going to be like how good and efficient it is at coding, how good and efficient it is at ML research, how good and efficient it is at knowledge work. But I don’t know how to like... Building those evals all seems tractable but hard. But then like how to make a breakthrough in fundamental chemistry seems really, really, really hard to measure. I was going to draw on like maybe frontier math as an example, but I think math is such an exception as like one of the most jagged pieces of AI. I think especially like open problems in mathematics are like the perfect target for rapidly improving AI because it’s like a falsifiable thing. And it’s like if we were to, say, see that in something that’s much more open-ended, I think I would update a lot. Or if the labs were like to come out and say, “Using Claude, we have a very, very big change in what our architecture of AI is,” to like there’s the famous like Jonathan Frankle–Sasha Rush bet, and it’s like, and the transformer is no longer like the lineage we are on. I think any of those things being very AI-driven would make me update a lot. But seeing more math, like I think I was surprised by the pace of math, but like not astonished.
如果真的出现了,我不会意外。但我认为情形会是:我们本来在一条斜坡上,爬山式优化可能带来斜率的短暂抬升,但随后我们会耗尽已知如何爬山的空间,增速再度放缓。所以,所有可测量的东西,我认为都会因为「可测量」而被非常快速地拉高。然后我们就进入了「该怎么测量」的领域。因为我接触过一些正在尝试的人……现在构建评估(evals)的成本非常高,而且我确实认为评估将会变成:编码有多好、多高效,ML 研究有多好、多高效,知识工作有多好、多高效。构建这些评估似乎都可行但都很难。但是「如何在基础化学上取得突破」这类事情,看起来真的、真的、真的非常难测量。我本来想拿前沿数学举例,但我觉得数学是 AI 能力中最「锯齿状」(jagged)的领域之一,是个特例。我认为尤其是数学公开问题,是快速进步的 AI 的完美目标,因为它是一个可证伪的东西。如果我们在一个开放性大得多的领域里看到类似的事情,我会大幅更新我的判断。又或者,如果实验室站出来说:「使用 Claude,我们的 AI 架构发生了非常、非常大的变化」——就像那个著名的 Jonathan Frankle 与 Sasha Rush 的赌约,transformer 不再是我们所处的技术谱系。我认为上述任何一件事如果是被 AI 强力驱动的,都会让我大幅更新。但只是看到更多数学成果——数学的进步速度确实让我意外,但还不至于震惊。
JS Denain · 00:16:49
That’s interesting to me. I definitely agree with this general sense. So like I think METR folks looking at like your nanoGPT results from autoresearch-style things compared to like what the humans were doing, it does seem like there’s this, I think Tom Cunningham calls this like the apple-picking model where AI is like much more efficient at the start, but then doesn’t actually like uncover as many new ideas. And you see this in this kind of optimizer research. Yeah, I mean, one thing I will say on this like verifiability point is like, I think a pretty common trend is like you’ll have some task that’s like not verifiable and you’re like, maybe you struggle to build an environment for it. But actually it’s like it’s a subset of a larger task that is itself like verifiable. It’s just like longer range. An example of this is like there are many like hard to verify tasks out of like companies. But in some sense, like revenue or like other like metrics, like valuations are like pretty legible. So that’s like one thing. I mean, the other thing is like expect things to be pretty jagged. But I think a big question is like, yeah, can you get, for a crazy world, can you get like a large, like self-sustaining industrial kind of explosion?
这对我来说很有意思。我确实同意这种总体感觉。比如,METR 的人把来自 autoresearch 式工具的 nanoGPT 结果与人类所做的工作进行对比,看起来确实存在这种现象——Tom Cunningham 把它叫做「摘苹果模型」(apple-picking model):AI 在开始阶段效率高得多,但实际上并不能发掘出那么多新想法。你在这类优化器研究中就能看到这一点。关于可验证性这一点,我想说的是一个相当普遍的趋势:你会遇到某个不可验证的任务,觉得很难为它构建环境。但实际上,它是一个更大的可验证任务的子集,只是时程更长。一个例子是:公司场景里有很多难以验证的任务,但从某种意义上说,营收或估值这类指标是相当清晰可读的。这是其一。其二就是要预期各种能力会相当锯齿状(jagged)。但一个重要的问题是:在一个疯狂的世界里,你究竟能不能得到一场大规模的、自我维持的工业爆炸?
Nathan Lambert · 00:18:05
Yeah. Well, can we talk about robotics and industry? Because I have a background in physical robots and like I think the robotics trends will look much closer to self-driving cars than LLMs. And I think that a lot of the singularity arguments are based on robotics being able to look much closer to LLMs than the self-driving cars roll out. So, why would you disagree? Or, what is the argument that mass industrialization and robotic expansion is doable? Because my prior is so suspicious that I maybe even haven’t given it enough justice, but I’m very suspicious of this being a viability, and mostly in terms of being a relative timeline. I think it could happen over decades, but I don’t think it’s a two to five-year concern.
对。那我们能聊聊机器人技术和工业吗?我有实体机器人的背景,我认为机器人技术的趋势会更接近自动驾驶汽车而非 LLM。而很多奇点论证都建立在「机器人技术会更像 LLM、而不是像自动驾驶汽车那样落地」的假设上。那么你为什么会不同意?或者说,大规模工业化和机器人扩张是可行的——这个论证是什么?因为我的先验是如此怀疑,以至于我可能都没有给予它足够的公正对待。我对这件事的可行性非常怀疑,主要是在相对时间线上。我认为它可能在几十年的尺度上发生,但我不认为这是两到五年内需要担心的事。
## Chapter 02 · 机器人与 AI 加速
JS Denain · 00:19:01
Two to five years seems rough, to be clear. I think I just don’t know as much about robotics here. I think is your main concern just reliability is really rough to get right in the same way that it was just a long tail of scenarios where things are, or was it more like a real-world thing where there’s much more regulation that comes up?
先说清楚,两到五年在我看来也太激进了。我对机器人技术了解不够多。你的主要担忧是「可靠性很难做好」吗——就像自动驾驶那样存在漫长的长尾场景——还是更多属于现实世界层面的问题,比如会遭遇更多的监管?
Nathan Lambert · 00:19:21
I think it’s building things is hard. I think that, let’s see. I’ll talk us through some of this. For example, I know places like Amazon, they build new factories to be robotic first, and those are more effective for them. And what this would take then is building a robotics factory. In the case of the US, it’s like you have to build a robotics factory that builds robots very efficiently in the US and then transition that or make a new one that is built by said robots. And I think the re-industrialization of the US is something that I think is like, there’s a lot of reasons why it is not happening. I think potentially in China it is more likely, but I also just haven’t been convinced by AI results on visual and action models that they’re progressing fast enough. I think I’ve had discussions with people in the multimodal field have described the techniques as being much more rudimentary and less developed than the text language models, and in need of much more fundamental innovation, where something like code plus RL is a very natural match that the hill climbing is very predictable. So—
我觉得是「建造东西」本身很难。让我想想,我来讲讲这方面的情况。比如我知道像亚马逊这样的公司,新建工厂时就是「机器人优先」设计的,那些工厂对他们来说效率更高。而这接下来需要的就是建一座机器人工厂。以美国的情况来说,你得先在美国建一座能非常高效制造机器人的工厂,然后再转产、或者新建一座由这些机器人来建造的工厂。而美国的再工业化这件事,我认为有很多原因导致它没有在发生。在中国这或许可能性更大一些,但我也并没有被视觉和动作模型方面的 AI 结果说服,觉得它们进步得足够快。我曾与多模态领域的人讨论,他们形容这些技术比文本语言模型原始得多、欠发达得多,需要多得多的根本性创新——而「代码 + RL」是一种非常自然的匹配,爬山过程非常可预测。所以——
JS Denain · 00:20:35
So, it seems like there’s two things. There’s the trends in robot capabilities is not as fast as you would expect for LLMs, and also even if robot capabilities were huge, it takes a while to build factories. I think I’m sort of skeptical of the second one. I’m just like, if robot capabilities are sufficient, the total addressable market for this is massive. And if you look at data centers in the US, there has been extremely fast build-out. If you had robots that were just literally able to substitute for blue-collar human workers, I feel like the financial incentives would be huge. And I think a lot of the reason why in some cases, the US doesn’t have huge build-out is just a demand thing. I think that’s the case for power, for example. So I think in that case, I’m just like, yeah, I feel like we just, what is the Tyler Cowen thing? Don’t underestimate the elasticity of supply is the main thing I would point to. I think on the capabilities front, I’m more uncertain. In particular, I’m sort of still confused and haven’t really looked into the, how much do you get directly actually from LLMs and foundation models for robotic capabilities? In particular, the other uncertainty I have is, it’s not clear to me that extremely fine-grained, extremely dexterous capabilities are the main thing you need for massive industrial explosions. And so, this longer tail of the hardest part of robotics, I’m not sure if that’s the biggest blocker for massive industrial explosion. Overall, robotics is something I have less expertise in. I’m interested in how many of the scenarios for doom ultimately kind of route through hard power acquired through robotics. I think part of my uncertainty also comes from, is it plausible to me that the minimum abilities that you need to acquire a lot of hard power and pose pretty catastrophic possibly extinction risks is more like, have access to nuclear codes or something like that? I don’t feel like I have great thoughts on this. I’m interested in more threat modeling, but I think that’s part of the thing is, what are the capabilities trends is something that people have disagreements about, and so what’s the minimum capability that’s necessary to cause these extinction-level harms, or harms that are sufficiently catastrophic, they just permanently alter the human trajectory?
那么似乎有两件事。一是机器人能力的趋势不如你对 LLM 的预期那么快;二是即便机器人能力很强,建工厂也需要时间。我对第二点其实比较怀疑。我的想法是:如果机器人能力足够,这件事的总可及市场(total addressable market)是巨大的。看看美国的数据中心建设,扩张速度极快。如果机器人真的能够直接替代蓝领工人,我认为经济激励会是巨大的。而且我认为,美国在某些情况下没有大规模建设,主要原因就是需求问题——比如电力就是这种情况。所以在这一点上,我会说——Tyler Cowen 那句话是怎么说的来着?「不要低估供给的弹性」,这是我最想指出的。在能力方面,我更不确定。特别是,我仍然困惑,也没有真正深入研究过:机器人能力到底有多少是直接来自 LLM 和基础模型的?另外我还有一个不确定点:我不清楚「极其精细、极其灵巧的能力」是否就是大规模工业爆炸所需的主要条件。所以,机器人技术最难的这条长尾,我不确定它是不是大规模工业爆炸的最大阻碍。总体而言,机器人技术是我专业较少的领域。我感兴趣的是,多少末日情景最终要经由「通过机器人获取的硬实力」来实现。我的部分不确定也来自:对我来说,「获取大量硬实力、构成相当灾难性的乃至灭绝风险」所需的最低能力,会不会其实更像是「拿到核密码」之类的东西?我对这个问题没有很好的想法,我想看到更多的威胁建模。但问题的一部分就在于:能力趋势本身就是人们有分歧的地方,那么,造成这些灭绝级伤害、或者那些灾难到足以永久改变人类轨迹的伤害,所需的最低能力到底是什么?
Nathan Lambert · 00:22:46
Yeah. The last point I would make on—
对。关于机器人我想说的最后一点是——
JS Denain · 00:22:47
I think that’s the kind of questions I want to see a bit more thinking on, but yeah.
我觉得这就是那种我希望看到更多思考的问题。嗯。
Nathan Lambert · 00:22:50
The last point I would make on robotics is that I think the robots will be very good in constrained and repetitive environments, like manufacturing robots, and I think much longer until there are robots walking around the street cohabitating with humans. And if I were to go deep on this, I would want studies and discussions with people that are building multiple different data centers to how much variety is in their job versus how much of it is you take box off of truck and you put box in location. And I don’t have any good signal on how clearly repetitive that is now versus more human dexterous and ingenuity in problem-solving.
关于机器人我想说的最后一点是:我认为机器人会在受限且重复的环境中非常出色,比如制造机器人;而要等到机器人在街上与人类共同生活,还需要长得多的时间。如果我要深入研究这一点,我会想与那些正在建造多个不同数据中心的人做研究和讨论:他们的工作中到底有多少是多样化的,又有多少只是「把箱子从卡车上搬下来、放到指定位置」。而对于现在这类工作到底有多明确的重复性、相比之下有多少需要人类的灵巧和解决问题的机智,我没有任何好的信号。
JS Denain · 00:23:34
Yeah. Although also currently, the environments have been designed around humans who are pretty flexible in those ways and have other constraints. You could imagine designing factories to be robot first is a thing that I think you’re mentioning Amazon, right? Sort of does that more now. And so you could also... Yeah, I think that’s the kind of stuff that jaggedness would get you, which is you might just have massive accelerations, including in the physical world of some industries, even if capabilities for fully being as dexterous or flexible as a human might not be there. Mostly, yeah. I think mostly, yeah, robot capabilities seem very important to track to me. We had some piece about this at Epoch, but we don’t claim robotics expertise.
对。不过也要看到,目前的环境都是围绕人类设计的,而人类在这些方面相当灵活,同时还受其他约束。你可以想象把工厂设计成「机器人优先」——我记得你在说亚马逊,对吧?它现在大体上就在这么做了。所以你也可以……对,我认为这正是「锯齿状能力分布」(jaggedness)能带给你的东西:即使「完全像人类一样灵巧或灵活」的能力还没到位,某些行业——包括物理世界中的行业——也可能出现大规模加速。总的来说,是的。我认为机器人能力对我来说是非常值得追踪的东西。我们在 Epoch 发过一篇相关文章,但我们并不自称机器人专家。
## Chapter 03 · 中国模型落后多少
Nathan Lambert · 00:24:21
Yeah. I agree. I think we could shift to another capabilities topic, which is how far behind do you think the top Chinese labs are of OpenAI and Anthropic? And you can define how you want to measure it, whether it’s like public models or like internal models. I think doing both is actually pretty interesting to think about. Like, how would you describe the gap? Like, choose your... This is one of the few things I’ll push you for a number on.
对,我同意。我觉得可以切换到另一个能力话题:你认为中国顶尖实验室落后 OpenAI 和 Anthropic 多少?测量方式由你定义——是公开模型还是内部模型。我觉得把两种都拿出来想其实挺有意思的。你会如何描述这个差距?你来选……这是少数几个我要逼你给出数字的问题之一。
JS Denain · 00:24:47
Yeah. I think I would go with like, I don’t know, six to eight months or something, roughly.
对。我想我会说,大概六到八个月左右吧。
Nathan Lambert · 00:24:53
From public to public?
公开对公开?
JS Denain · 00:24:56
Yeah. Like, release date to release dates. I don’t have a great catch numbers on like how long the internal to public deployment. Yeah, I’m sorry if it increases a bit if you’re counting when the model was built, because I would expect the delay to be larger for OpenAI and Anthropic than it is for Chinese labs. But yeah, I don’t know, just looking at ECI and there’s a few different methods you can do there, and there’s a good amount of noise between. Those methods are kind of reasonable, and my sense is they give you something on the order of like six to eight months-ish.
对,发布日期对发布日期。至于「内部完成到公开发布」的间隔有多长,我没有很好的把握数字。抱歉,如果按模型构建完成的时间来算,差距可能还会稍微扩大一些,因为我预期 OpenAI 和 Anthropic 的「构建到发布」延迟比中国实验室更大。总之,就看 ECI 而言,有几种不同的计算方法,它们之间有不少噪声,但都还算合理,我的感觉是它们给出的量级大约在六到八个月上下。
Nathan Lambert · 00:25:28
I would say that like Kimi K3 and GLM 5.2 are closer to like two to three or four. So do you think those are anomalies down to measurement or overfitting? So I have this discussion a lot with Florian. And Florian, who helps me with Interconnects, is constantly badgering me down. And I think I intuitively have landed something closer to you. And I think those two models, and in particular Artificial Analysis, were very close. I think Kimi might have been even under two in the Artificial Analysis Index at the time. And I’m just putting this out there, and I go back and forth all the time on it.
我会说 Kimi K3 和 GLM 5.2 更接近两到三四个月。那你觉得这些是测量方法或过拟合造成的异常值吗?我和 Florian 经常讨论这个。帮我做 Interconnects 的 Florian 一直在不断地向我施压。而我直觉上最终的答案更接近你给的数字。不过那两个模型,尤其是在 Artificial Analysis 的指数上,差距非常小。我记得当时 Kimi 在 Artificial Analysis 指数上甚至不到两个月。我把这个观点摆出来——其实我在这件事上一直反反复复。
JS Denain · 00:26:12
So I don’t remember the especially most up-to-date details on the Artificial Analysis Index. My sense is that it might understate the gap for curation reasons or something, but I don’t want to be too confident there because also they update methodology and stuff like that. I think even in ECI, though, there are some cases where it was more like four months. Yeah, I don’t know. Four to eight months seems reasonable to me. I think like two months, I would be like, “Nah, that seems like a bit more overfitting-y.” We did internally look into a bit how much overfitting explains the gap. Like, just doing the kind of like, what’s the ECI lag analysis for, if you just take an ECI based on private benchmarks versus not, or private benchmarks plus results were from models that were from benchmarks that were published after a model was released or something like that, where there’s no risk of contamination. I think overall, that effect was basically not statistically significant, which was interesting. I think if you did rely just results in model cards as opposed to the results being put in ECI, we probably get some contamination or overfitting effects. I still think there’s some amount of, yeah, something like ECI might underestimate the gap just because I do think OpenAI and Anthropic are probably like... There’s probably other capabilities just would appear less in benchmarks and where there’s been more optimization or serving a broader set of users. But yeah, I don’t know. That’s my overall number.
我对 Artificial Analysis 指数最新的细节记不太清了。我的感觉是,它可能因为筛选(curation)方面的原因低估了差距,但我不想在这点上过于自信,因为他们也会更新方法论之类的东西。不过我想,即使在 ECI 里,也有一些案例更接近四个月。嗯,我说不好。四到八个月对我来说是合理的。如果是两个月的话,我会说:「不行,那看起来更有点过拟合的味道。」我们内部确实研究过过拟合能在多大程度上解释这个差距。比如做那种 ECI 滞后分析:只用私有基准来构建 ECI,或者使用「模型发布之后才公布的基准」的结果——这样就没有污染(contamination)风险。总体上,这个效应基本不具统计显著性,这挺有意思。我想,如果只依赖模型卡片(model card)里的结果,而不是被纳入 ECI 的结果,大概会出现一些污染或过拟合效应。但我仍然认为,像 ECI 这样的东西可能低估了差距,因为我确实认为 OpenAI 和 Anthropic 可能……还有一些别的能力在基准中体现得较少,而那些方面恰恰有更多优化、或服务于更广泛的用户群。但总之,这就是我给出的整体数字。
## Chapter 04 · 蒸馏与差距
Nathan Lambert · 00:27:39
If we were to ban distillation effectively, not even just ban, but if distillation were effectively be stopped, where do you think the number would be in six to 12 months? I think without RSI being super crazy. I think RSI going super crazy, the labs pull ahead by a lot more.
如果我们要有效禁止蒸馏——甚至不只是禁止,而是蒸馏实际上被停止了——你认为六到十二个月后,这个差距的数字会是多少?我的前提是 RSI 没有疯狂爆发;如果 RSI 真的疯狂起来,实验室会领先得多得多。
JS Denain · 00:28:01
Yeah. On current trends, I think I’ve actually updated towards distillation is actually a really big factor. We can talk about the different factors. And so, okay, so currently if I’m saying six months gap, then in six months, it’s probably not literally 12 months, right? So, my guess is, yeah, you are at like eight or nine, something like that. You go from like six to nine maybe.
对。按照当前趋势——我实际上已经更新了看法,认为蒸馏确实是一个非常大的因素。我们可以聊聊各个不同的因素。那么,如果我现在说差距是六个月,那六个月之后大概率不会是字面上的十二个月,对吧?我猜大概是八到九个月左右,差不多这样。从六个月变成九个月左右。
Nathan Lambert · 00:28:31
Why have you updated on distillation being effective?
你为什么更新了对「蒸馏有效」的看法?
JS Denain · 00:28:35
Yeah. So I think it’s like, yeah, there’s two reasons. I think, a lame reason is, I don’t know, more people seem to be saying it’s this.
对。我认为有两个原因。一个比较无力的理由是:不知道为什么,似乎更多人开始这么说了。
Nathan Lambert · 00:28:45
They have been. I’m surprised by it.
确实有人在这么说。这让我有点意外。
JS Denain · 00:28:47
Yeah. The Stolen Thoughts paper did suggest it was actually relatively easy to get the stuff. Yeah, random gossip. I think also a big one is, we can talk about this, thinking about the other explanations for the lag and them not seeming as compelling as when I first thought of them. I do think the Claude routers thing also just seems like a pretty big deal. And initially when I thought of distillation, I hadn’t considered that. But I do think Claude routers giving the kind of right prompt distribution for realistic usages, use cases and stuff like that just seems quite useful.
对。Stolen Thoughts 那篇论文确实表明,拿到这些东西其实相对容易。对,一些随机的坊间传闻。另一个重要原因是——这个我们可以展开谈——我重新考虑了滞后现象的其他解释,发现它们不像我最初设想时那么有说服力了。我也认为 Claude 路由那件事本身就是件相当大的事。我最初考虑蒸馏时没有想到这一点。但我确实认为,Claude 路由提供了符合真实用法、真实用例的正确提示词分布(prompt distribution),这看起来相当有用。
Nathan Lambert · 00:29:26
But it’s also like these companies have their own usage at this point. And it’s also like we have the benchmarks. So the benchmark distribution we already have. So I don’t necessarily think distillation is helping with... I think the routers could be very helpful, but I was confused by that prompt distribution thing because once you have the benchmark distribution, you just make similar examples or find similar examples.
但这些公司到现在也都有自己的真实使用数据了。而且我们有基准测试,基准的分布我们已经有了。所以我不认为蒸馏的帮助在于……我认为路由器可能非常有用,但那个「提示词分布」的说法让我困惑:因为一旦你有了基准的分布,你直接造类似的例子、或者找类似的例子就行了。
JS Denain · 00:29:50
Yeah, so I agree. So I think the Claude routers just give you a bunch of useful data to train on, and that will generally improve capabilities. I think that’s one explanation. I agree that I think giving you the right prompt distribution is, I think, going to be useful for real-world capabilities. I agree that purely if I’m discussing this ECI lag or something, then yeah, you can just use the prompt distribution for benchmarks. And so I think it’s not going to be that good of an explanation there. Yeah. I think just... Yeah. Also, so as an example, right, people saying that mid-training is a really important thing or something. I think actually in that conversation, right, Beren was like, “Mid-training is actually getting you 80% of the way there.” And more claims of this form and generally of RL being very useful but not doing that much of the exploration work, I think is also evidence that doing SFT on language trajectories is really useful.
对,我同意。我认为 Claude 路由确实给了你一大批可用于训练的有用数据,这通常会提升能力,这是一种解释。我同意,「给你正确的提示词分布」对现实世界能力会有用。我也同意,纯粹在讨论 ECI 滞后这类问题时,你完全可以用基准的提示词分布来替代,所以在这上面它不是一个那么好的解释。对。另外举个例子,人们说中期训练(mid-training)是非常重要的环节。我记得在那次对话里,Beren 就说过:「中期训练实际上帮你走完了 80% 的路程。」这类说法越来越多,再加上「RL 非常有用、但并没有承担太多探索工作」的普遍观点,我认为这也是「对语言轨迹做监督微调(SFT)真的非常有用」的证据。
Nathan Lambert · 00:30:48
Yeah. I want to go through—
对。我想逐条过一遍——
JS Denain · 00:30:50
I think he mentioned on a post on this is, it’s a good initialization, but I guess I’m updated that this initialization is really, really important. And yeah.
我记得他在一篇帖子中提到,这是一个很好的初始化。但我的更新是:这个初始化真的、真的非常重要。对。
Nathan Lambert · 00:30:59
Yeah, because I’m still on the side that I think doing RL well and doing RL faster so you can go bigger is the way people are getting capabilities. But I have been hearing more about this repeated... The framework would be it’s a very repeated cycle between mid-training SFT and RL, and then your peak RL helps you feed into mid-training and less of a very big RL run, which I never thought... The RL runs are a week probably. I don’t think they’re insane, especially like Zhipu or Kimi. And that’s... So I could see this, and I was like, “I don’t really know.” I generally thought that because the models are getting so useful, I don’t know how... It just seems like the scale of distillation would need to be so big to really do that for mid-training. And the counterargument is Kimi and GLM 5.3 are also strong models, where it’s like, if the gap is that small, it just doesn’t make sense to me that the help would be so big. That’s why I’m still on the not convinced, but looking for more evidence. And then some of the other re... I have this blog post that I wrote in front of me. If you want to talk about distillation more, you can get that comment in before I switch to other topics.
对,因为我仍然倾向于认为:把 RL 做好、把 RL 做得更快从而能做得更大,才是人们获得能力的方式。但我也听到了越来越多关于这种循环的说法……这个框架是:中期训练 SFT 与 RL 之间形成非常反复的循环,然后你峰值水平的 RL 成果反哺进中期训练,而不是依靠一次超大规模的 RL 运行——这一点我从来没想过……RL 运行大概也就一周。我不认为它们有疯狂那么大,尤其是智谱(Zhipu)或 Kimi 的。所以我能想象这种模式,然后我会想:「我还真说不准。」我原先的普遍想法是:模型已经变得这么有用了,我不知道……看起来蒸馏的规模必须非常大,才能真正对中期训练起到这种作用。而反驳的观点是:Kimi 和 GLM 5.3 也是很强的模型——如果差距真的那么小,那「帮助有那么大」在我看来就说不通。这就是为什么我仍然站在「未被说服,但寻找更多证据」这一边。还有一些其他的……我手边就有我写的这篇博客文章。如果你还想多聊蒸馏,可以趁我切换到其他话题之前把你的评论放进来。
JS Denain · 00:32:21
I guess I’m pretty interested in talking about the alternative explanations or something for... I think there’s this general phenomenon of Chinese labs have way less capital and particularly way less compute than US labs. And that delay is huge. And then this, whether it’s four months or eight months, it’s a much shorter delay in capabilities than in capital. And so, this requires some explanation.
其实我对讨论替代性的解释更感兴趣……有这么一个普遍现象:中国实验室的资本远少于美国实验室,尤其是算力少得多。这个差距是巨大的。而无论最终是四个月还是八个月,能力上的滞后都远小于资本上的滞后。这就需要某种解释。
Nathan Lambert · 00:32:48
Yeah. Do we think the Chinese labs are still releasing meaningfully faster from time that RL is done to public gets the API and evaluation scores? In the past, I thought that the time to release was much faster, and I think the labs are releasing intermediate versions faster now, so I don’t know if that explains as much of it. But I would say a year ago, I would put a lot more to Chinese models get model out within days, American labs could take months, and that would artificially squeeze the gap very substantially.
对。你认为中国实验室从「RL 训练完成」到「公开发布、开放 API、公布评测分数」的间隔,是不是仍然明显快于美国?过去我认为他们的发布速度快得多,而我觉得现在美国实验室发布中间版本的速度也变快了,所以我不确定这还能解释多少。但要说一年前的话,我会更看重这一点:中国模型几天之内就能发布,美国实验室可能要几个月,这会人为地把表观差距大幅压缩。
JS Denain · 00:33:26
Why would it squeeze the gap that much?
为什么会压缩那么多差距?
Nathan Lambert · 00:33:28
Because you have the trajectory of capabilities, and higher one is OpenAI and Anthropic, and they stop training here in time, and then the Chinese labs are here. But then it’s just like the model is stagnant before it gets released.
因为能力轨迹是一条线,高位上是 OpenAI 和 Anthropic,他们在某个时间点就停止了训练,而中国实验室当时还在更靠后的位置。随后模型在发布之前就一直停滞在那里。
JS Denain · 00:33:44
Yeah, I think this depends on the method that... This both depends on the method that you use for computing the lag or something, right? So my sense, I think when I was saying four to eight months, I think a lot of that uncertainty interval also comes from, are you measuring the method by looking forward or backward or something? Or how are you resolving the uncertainty? Are you taking this kind of staircase or this kind of staircase, or interpolating or something like that? So I think that’s kind of still accounted for in the uncertainty. So my guess is that’s not a huge... Or that’s still, even with this, I think there’s still a large effect to explain. And I think, yeah, these are other potential explanations, right? So one is maybe there’s a big delay in compute, but in labor or potentially data, there’s less of a delay, and those are important factors. And so even if you’re two years behind in compute, if you’re six months behind in data and in fact ahead in number of researchers or something, or not that far behind in number of researchers, maybe that helps catch up, and that’s not even a spillover effect, right? That’s just a reason. Yeah, there’s distillation. Other explanations people have are just ideas might leak, and I don’t suspect that’s a huge effect. People can play with a model, and through playing with the model, they kind of infer maybe what it was trained on or what’s useful to push on is another explanation. Those things are not quite like distillation, but using Claude as your reward model or using Claude to clean data or something, maybe have some spillovers.
对,我想这取决于……这同时取决于你用什么方法来计算滞后,对吧?我的意思是,我说四到八个月时,这个不确定性区间里很大一部分也来自于:你是向前看还是向后看来测量?你如何处理不确定性?是取这种阶梯还是那种阶梯,还是做插值之类的?所以我认为这一点已经包含在不确定性之内了。我的猜测是,这不会是一个特别大的……或者说,即使考虑这一点,我认为仍然有很大的效应需要解释。那么,对,这些是其他潜在的解释,对吧?其一:也许算力上有很大延迟,但在劳动力或数据上延迟较小,而后者是重要因素。所以即使算力落后两年,如果数据只落后六个月、研究人员数量甚至领先、或者没那么落后,也许这有助于追赶——这甚至还算不上「溢出效应」(spillover),对吧?它只是一个直接原因。对,还有蒸馏。人们提到的其他解释包括:想法可能会泄露,不过我怀疑这不是一个很大的效应。还有一种解释是:人们可以玩你的模型,通过把玩模型来推断它可能是用什么训练的、往哪个方向推进有用。这些并不完全等于蒸馏,但「用 Claude 当你的奖励模型」或「用 Claude 清洗数据」之类的做法,也许存在一些溢出效应。
Nathan Lambert · 00:35:23
Let’s see. I’m trying to quantify some. I would say that I think the Chinese labs care about benchmarks a bit more for financial... Some of them are public companies, and showing close benchmarks helps them a lot. So I do think they care about it more. I don’t know if that’s going to give you a month or two. I don’t know what are you going to give back, like a month or two. I think there’s a good chance that the Chinese labs are better at organizing talent on just doing really mundane hill-climbing data work. I don’t think that’s a huge effect, but it’s just like they have a ton of talent, and culturally through the way that... I think that there’s a good chance that it’s just more grind. They might actually grind more effectively than the American labs, which is... I don’t know how. I wouldn’t put a lot to this because I think it’s fairly close, but I think that’s a chance. But that’s a very marginal... That’s not a gigantic lead cause. I would put more of it to compute difference than to distillation. But maybe distillation is very related as a compute difference because it’s a way to turn... It is a definition of way to turn money into very high-quality data, which is something you would otherwise need compute for.
让我想想,我试着量化其中一些。我认为中国实验室出于财务原因对基准测试更在意一些……他们当中有些是上市公司,展示接近的基准成绩对他们帮助很大。所以我确实认为他们更在意这个。我不知道这值不值一到两个月。它能回馈多少,我说不好,也许一到两个月。我认为很有可能有这样的情况:中国实验室更擅长组织人才去做那种非常单调枯燥的爬山式数据工作。我不认为这是巨大的效应,只是他们有海量的人才,而且文化上通过那种方式……很可能就是「更能磨」(grind)。他们磨起来可能真的比美国实验室更高效,这……怎么说呢。我不会在这上面放很大权重,因为我觉得差距不大,但机会是存在的。不过这只是很边际的因素,不是一个巨大的领先原因。我会把更多归因于算力差异,而不是蒸馏。但也许蒸馏与算力差异高度相关,因为它是一种把……它本来就是「把钱变成极高质量数据」的一种定义性方式,而这本来是需要算力去换的。
JS Denain · 00:36:35
Yeah. Another theory that I’ve vetted about, and I’m not sure how big of a deal it is, is there’s this data market in the US, and maybe one thing that happens is the best RL environments or evals, it kind of takes a lot of compute actually to figure out which ones they are. And so maybe there’s kind of a collaboration between data providers and AI labs to actually test and figure out what RL environment really worked. And then maybe that data provider, once they’ve done this iteration, which implied a lot of R&D compute spending from a frontier lab, then they’ll build a bunch of similar RL environments because they’ve learned the lesson, and then they’ll sell them with some delay, but still sell them to other people, including in China.
对。另一个我琢磨过的理论——不确定它有多重要——是:美国有一个数据市场,也许发生的事情是:最好的 RL 环境或评估,实际上需要花大量算力才能甄别出来。所以也许数据提供方和 AI 实验室之间存在某种协作,来实际测试、弄清楚哪些 RL 环境真正有效。然后,这个数据提供方在完成这种迭代之后——这种迭代隐含了前沿实验室大量研发算力的投入——就会照着学到的经验再做一批类似的 RL 环境,然后延迟一段时间,但仍会把它们卖给其他人,包括中国的买家。
Nathan Lambert · 00:37:21
I’ve heard this from people.
我听人说过这个。
JS Denain · 00:37:22
And so there’s kind of this implicit R&D compute that was spent and that it gets saved. I’m not sure how big of a deal that is.
所以,存在一种隐性的研发算力被花掉了、然后又被「省下来」的情况。我不确定这有多重要。
Nathan Lambert · 00:37:29
I’ve heard this multiple times, including from people in China that have... This is like multi-hop type of rumor that I’ve heard a few times is like, we just have to wait a certain amount of time and then we buy the RL environments that Anthropic bought for a 10th of the price. And I think this could contribute a lot to capital efficiency, but also as somebody who buys into human factors being very important in model progress, which is just like competition, I think the analog to the competition that OpenAI and Anthropic feel right now is proof of concept as a way to make something way easier. And I do think the OpenAIs and Anthropics of the world are much more likely to innovate in open-ended things like Navier-Stokes, multi-agent mega-scaling than the Chinese labs. And having talked to many of the labs, I don’t think they would contest this, but they probably won’t put it on the record. But they’re just like, trying to keep up is so much easier.
这种说法我听过好几次,包括从中国那边的人那里……这是一种我多次听到的「多跳式」传闻:只要等上一段时间,就能以十分之一的价格买到 Anthropic 买过的那些 RL 环境。我认为这可能对资本效率贡献很大。但与此同时,作为一个相信「人的因素对模型进步非常重要」的人——也就是竞争本身——我认为 OpenAI 和 Anthropic 现在感受到的竞争,其类似物就是「概念验证」(proof of concept):有人证明某件事可以做成之后,做起来就容易得多。我也确实认为,在开放性的方向上——比如纳维-斯托克斯方程(Navier-Stokes)、多智能体超大尺度扩展——OpenAI 和 Anthropic 比中国实验室更可能做出创新。我和很多实验室聊过,我认为他们不会否认这一点,只是可能不愿意记录在案。因为「追赶」实在容易太多了。
JS Denain · 00:38:27
Yeah. So that’s more like the... Yeah, so the way I describe this was like four-minute mile style effects of like, you show that something is possible at all and then people have the conviction to go down that route, don’t waste a ton of resources exploring a bunch of other things, is the thing you’re pointing at here.
对。这更像是那种……对,我用「四分钟一英里」式的效应来描述:你证明了一件事原则上可行,然后人们就有了沿这条路走下去的信念,不用在大量其他方向上浪费资源去探索——这就是你在这里指的东西吧。
Nathan Lambert · 00:38:43
Yeah. And I think this—
对。而且我认为这——
JS Denain · 00:38:44
I guess I’m looking for examples where you think this... What are examples? Because for example, reasoning models is not this, right? Like, DeepSeek Math or whatever came way before o1. Yeah, I’m kind of curious if... Yeah, I agree this seems kind of plausible, and I’m not sure I can come up with examples of big innovations that a frontier lab has—
我在想这方面的例子……有哪些例子?比如推理模型就不算,对吧?DeepSeek Math 之类的比 o1 早得多。对,我有点好奇……对,我同意这看起来挺合理的,但我不确定自己能举出「前沿实验室做出了某个重大创新」的例子——
Nathan Lambert · 00:39:04
I think it’s more in org structure. So it’s like there’s R&D and modeling compute at the labs, which I think kind of get lumped together. And realistically, make-model-better compute of the next generation model versus the two or three generations down the line is very different. And I would think that the Chinese labs are just spending on a shorter time horizon. And then if there’s a major innovation in architecture or something that gets bubbled around the US ecosystem, I would assume the Chinese labs will figure out as well. I don’t think that an architecture innovation is kept very well between Anthropic, OpenAI, Meta, and Google. I think that these are all leaked very quickly through personnel turnover.
我认为更多体现在组织结构上。实验室里有研发算力和建模算力,我觉得这两者常被混为一谈。但实际上,「让下一代模型更好」的算力与「两三代之后的模型」的算力是非常不同的。我认为中国实验室就是在更短的时间视界上花钱。而如果架构或其他方面出现了重大创新,在美国生态圈里传开,我会假设中国实验室也会弄明白。我不认为一项架构创新能在 Anthropic、OpenAI、Meta 和 Google 之间保密很久。我认为人员流动会让这些很快泄露出去。
JS Denain · 00:39:50
I see. So you think that actually has a big effect. So basically, I think it seems like you are just like, you think that with the other explanations, you can just get pretty far, such that you don’t really need distillation to explain a large fraction of the gap.
明白了。所以你认为这确实有很大影响。所以基本上,我理解你的意思是:靠这些其他解释,你就能解释得相当充分,以至于并不真的需要蒸馏来解释差距的很大一部分。
Nathan Lambert · 00:40:03
Yeah. So, I think without distillation, the gap would be fairly similar. It’s like also just building these models, there’s so much low-hanging fruit, and I don’t think distillation plugs that much of the low-hanging fruit that you are doing. It’s very unclear. It’s like once you establish your reasoning trace as being... This isn’t proven, but I think in mid-training and SFT, you need to have a pretty distinctive style in your reasoning trace to kind of stack it and have a defined reasoning strategy for the model. And Kimi and GLM have this, and I think they could modify it from where they are. And it’s just like, how does that compound over time if Anthropic and OpenAI change way faster, maybe it matters more. I don’t know. Doesn’t sound like we’re getting somewhere. I did like the post you had on understanding Chinese job postings, which I thought was a very clever way to try to peek behind the curtain of the Chinese AI industry. So I don’t know if you have anything you thought was particularly fun about this. It’s like, it was so hard to understand the industry that is going on there from outside.
对。所以我认为,即使没有蒸馏,差距也会相当接近。而且构建这些模型时,低垂的果实实在太多,我不认为蒸馏能补上你正在摘的那些低垂果实中的多大比例。这一点非常不清楚。比如,一旦你确立了自己的推理轨迹风格……这并没有被证明,但我认为在中期训练和 SFT 里,你的推理轨迹需要有相当独特的风格,才能把它堆叠起来,为模型形成明确的推理策略。而 Kimi 和 GLM 已经有了这个,我认为他们可以在现有基础上进行修改。至于随着时间推移这会如何复利——如果 Anthropic 和 OpenAI 变化快得多,也许它就更重要。我说不好。听起来我们聊不出什么结论。我确实很喜欢你那篇从中国招聘启事里找线索的文章,我认为那是一种非常聪明的方式,去窥探中国 AI 产业的幕布之后。所以不知道你觉得这里面有什么特别有意思的东西?毕竟从外部理解那里正在发生的产业实在太难了。
JS Denain · 00:41:22
Yeah. So this is work by Cheryl Wu and I. I think it’s, as a source of evidence, it’s more like you can get interesting anecdotes or interesting facts. I think it’s not so much the kind of Epoch-y thing where you can get a trend line that you really follow really well. I think some job posting trends are good for this, but I think especially for China, it is a bit more like, “Oh, well, you can see they’re hiring in this region for data center roles, and it seems like that suggests that at least some of these labs are basically constructing their own data centers as opposed to renting compute from Alibaba or whatever.” So you get a few kind of nice facts like this. I think you also do understand a bit more what kinds of product strategies the different companies have and what they’re aiming for. So I think it’s pretty interesting for that. This post was now published in June, so things move fast and things may have changed. But yeah, I think there are interesting takeaways on company strategies, on how they—
是的。这是我和 Cheryl Wu 合作完成的工作。我认为,作为一种证据来源,它更像是能让你获得一些有趣的轶事或事实。它不太像那种典型的 Epoch 式研究——能画出一条可以长期追踪的趋势线。有些招聘趋势确实适合这么做,但尤其是对中国来说,它更像是一种「哦,你看,他们在这个地区招数据中心岗位,这似乎表明至少有一部分实验室基本上是在自建数据中心,而不是从阿里云之类的地方租用算力」。所以你能得到一些这样不错的事实。我觉得你也能更了解这些公司各自有什么样的产品策略、他们的目标是什么。所以就这一点而言挺有意思。这篇文章是六月发布的,所以事情变化很快,情况可能已经变了。不过是的,我认为在公司战略等方面有一些有趣的发现,比如他们是如何——
Nathan Lambert · 00:42:31
Can you say more about company strategies? Because I think that a lot has been cast on, say, like... The different company strategies in China. It’s like, what is DeepSeek’s strategy? I think MiniMax is one of the clear ones, and then Zhipu. And Zhipu has some on-premises deployment stuff, but at the high level, I think Zhipu can be much closer to OpenAI and Anthropic. But do you agree with this, or do you think any of them are more defined or have more interesting different things?
你能多讲讲公司战略吗?因为我觉得关于中国各公司的不同战略已经有很多讨论了。比如,DeepSeek 的战略是什么?我认为 MiniMax 是战略最清晰的公司之一,然后是智谱。智谱有一些本地化部署的业务,但从高层来看,我认为智谱可以更接近 OpenAI 和 Anthropic。你同意这个看法吗?还是说你觉得其中某些公司的战略更明确、或者有更有意思的不同之处?
JS Denain · 00:43:03
Yeah. I mean, one thing is just, I think we have this plot of how many job postings there are for B2B sales. As an example, it really does seem like Z.ai, like Zhipu, has a lot more of them than MiniMax or Moonshot. I think also, they have different strategies in terms of how much they want to expand internationally. I think MiniMax is a decent amount of that, more so than Z.ai, I think was the thing we found. I think there’s a few things like this. I think for DeepSeek, we didn’t see as much of that, for example.
是的。我是说,举个例子,我们做了一张关于 B2B 销售岗位招聘数量的图。从这张图看,Z.ai(也就是智谱)的这类岗位确实比 MiniMax 或月之暗面(Moonshot)多得多。另外,在国际化扩张的力度上,它们的策略也不同。我们发现 MiniMax 在这方面的投入相当大,比 Z.ai 更多。类似这样的发现还有几条。比如 DeepSeek,我们没有看到太多这类迹象。
Nathan Lambert · 00:43:40
Having done this analysis, do you think you could hand an AI model your taxonomy and have it redo it every three months? Do you think this is now a thing that Epoch could almost automate?
做完这个分析之后,你觉得能不能把你的分类体系交给一个 AI 模型,让它每三个月重做一遍?你觉得这现在几乎是 Epoch 可以自动化的事情了吗?
JS Denain · 00:43:53
So I think we do have some upcoming project on job postings. I think specifically for this kind of thing, I feel like the takeaways are kind of ad hoc or something. And so I think it relies a bit more on you have a bunch of this data, what actually seems interesting? And I feel pretty often that LLM’s assessment of what are the top five most interesting things is not that great. But one example of a thing where I think... So I actually have this really crappy vibe-coded job listings tracker, which looks a bit more like the quality’s better for an OpenAI Anthropic. And I think Epoch might have something on this in a bit. But one example where AI is pretty useful is just, I don’t know, you just want to reasonably classify jobs as are they basically research jobs or are they basically engineering jobs? Or maybe research engineering is actually hard, but are they research jobs or are they GTM jobs? And the structure of the teams are going to be not coherent across different companies, but you can use AI to automatically track this over time and have some coherent categories. So then you do get trends like, “Oh, it seems like there’s been a surge in hiring from this frontier AI lab, and it’s basically mostly been sales, or it’s been mostly hardware infrastructure.” I think that’s pretty cool, interesting, and automatable.
我们确实有一些即将开展的招聘数据项目。但具体到这种事,我觉得结论有点临时拼凑的感觉。它更多依赖的是:你手里有一堆数据,哪些东西看起来真的有意思?而且我常常觉得,LLM 对「最有意思的五件事是什么」的判断并不太好。不过有一个例子……我其实有一个用 vibe coding 做出来的很粗糙的职位追踪器,对 OpenAI、Anthropic 这类公司,它的质量会好一些。我想 Epoch 稍后可能也会推出类似的东西。但 AI 确实很有用的一个例子是:你想合理地把岗位分类——它基本上是研究岗还是工程岗?研究工程岗可能确实难分,但它到底是研究岗还是 GTM(走向市场)岗?不同公司的团队结构并不一致,但你可以用 AI 随时间自动追踪,并保持一套连贯的分类。这样你就能得到一些趋势,比如「哦,这家前沿 AI 实验室的招聘似乎激增了,而且基本上主要是销售岗,或者主要是硬件基础设施岗」。我觉得这挺酷、挺有意思,而且可以自动化。
Nathan Lambert · 00:45:14
Yeah. I think if you do this again, I’m interested in if you find things on data market expansion, which would be like your job is buy data. Because I’ve heard from many people that the Chinese data market is exploding, and I have poked various, whether it’s people I know at labs or people who I know follow Chinese industry closely. And it’s like, they’re like, “Yeah, but I can’t get anyone on the phone to know what this manifests as and what their budgets might be,” because Anthropic famously has billion-dollar budgets. And it’s just like I think it very quickly can become very important, like compute export control discussions stuff. By the end of the year, I suspect there will be some article talking about this and going deep reporting it. But from my perspective, getting that reporting information is near impossible.
是的。如果你们再做一次这个分析,我感兴趣的是你能否在数据市场扩张方面有所发现——也就是说,某些人的工作就是买数据。因为我从很多人那里听说,中国的数据市场正在爆发,我也打听过各种人,无论是我在实验室认识的人,还是我认识的密切跟踪中国行业动态的人。他们的反应都是:「是啊,但我没办法给任何人打电话问清楚这具体表现为什么、他们的预算可能有多少」,因为众所周知 Anthropic 有着数十亿美元级别的预算。我觉得这件事很快就会变得非常重要,就像算力出口管制的讨论那样。我猜到今年年底,会有某篇文章深入报道这个话题。但在我看来,要拿到这种报道所需的信息几乎不可能。
JS Denain · 00:46:05
Yeah. I think data is just really rough. I think for Epoch, data has been a tricky thing. It’s obviously an enormously important factor, but it’s harder to quantify or commoditize, and it’s also quite secretive. And so it’s like, I think a lot of the information is gossip. It’s hard to know how much to trust. My sense on Chinese, I think that article actually has something on this. Just it does seem like there’s a lot more in-housing in general by Chinese companies, and I think this also applies to data. And kind of relatedly, actually, there’s a lot of hiring for intern roles. I think if you go to the jobs listings pages for a lot of these companies, there’s specifically two tabs. They have summer internship tab or the internship tab and the normal hiring tab. And there’s a lot of, I think, hiring fairly junior people, and some of that might be for data purposes. But you did also see a surge in in-housing for data in the frontier AI companies. I’m not sure if this is still the case, but xAI was the only company that had this, but it was kind of nice because if you went to the careers page, there was actually the human data category, and you could just see which data roles they were hiring for. So there’s stuff to do on job postings on the data front as well, both xAI. I did this with Mercor and a few others previously. But I think it’s similarly, I think the most interesting things have been like, “Oh, well, that’s a crazy-ass role.” xAI is hiring for meme specialists or whatever, and it’s more ad hoc fun things than great trends, at least from what I’ve seen.
是的。我觉得数据这个领域真的很难搞。对 Epoch 来说,数据一直是个棘手的问题。它显然是一个极其重要的因素,但更难量化、更难商品化,而且相当不透明。所以很多信息其实都是坊间传闻,很难判断该信多少。至于中国的情况——那篇文章里其实提到了这一点——总体来看,中国公司的「内包」(in-housing,自建团队而非外包)趋势明显更强,我认为这也适用于数据。顺带相关的一点是,实习岗位的招聘非常多。如果你去看这些公司的招聘页面,会发现专门有两个标签页:一个是暑期实习/实习标签页,一个是常规招聘标签页。他们招了很多相当初级的员工,其中一部分可能就是出于数据方面的目的。不过你也确实看到前沿 AI 公司在数据方面出现了内包激增。我不确定现在还是不是这样,但 xAI 曾是唯一有这种设置的公司,这其实挺方便的:你去看它的招聘页面,真的有一个「人类数据」类别,可以直接看到他们在招哪些数据岗位。所以在数据方面,招聘信息也有很多可做的——包括 xAI。我之前还分析过 Mercor 和其他几家公司。但类似地,我觉得最有意思的发现往往是那种「哦,这个岗位也太离谱了」。比如 xAI 在招「梗图专家」之类的,这更像是一些临时性的趣闻,而不是什么大趋势,至少就我所见是这样。
Nathan Lambert · 00:47:35
Yeah. I think that this is not going to change, unfortunately. It seems very much like individual teams at labs have contacts at data companies, and all of this is done privately, and it’s not... I guess even tracking compute is fairly hard, but now data centers are a manifestation that is somewhat trackable. And NVIDIA is a public company, and that is what is done. If the data companies were public, it would probably be easier to tease some things apart.
是的。遗憾的是,我认为这种情况不会改变。看起来非常像是各实验室的个别团队与数据公司有私人联系人,而这一切都是私下进行的,而且……我想说,即使是追踪算力也相当困难,但如今数据中心至少是一种多少可以追踪的具象化形式。英伟达是上市公司,人们做的就是基于公开信息的这类分析。如果那些数据公司也是上市公司,很多事情可能就更容易理清了。
## Chapter 06 · 开放与闭源安全
JS Denain · 00:48:13
Agree.
同意。
Nathan Lambert · 00:48:13
Okay, we have another timely topic. How do you feel about frontier model safeguards? Given that in the last 24 hours, we learned that three people used public Claude models to hack OpenAI and get internal access, which is just crazy to me. Did you see this? It’s genuinely surprising to me that this is the leaky world we are in. At the same time, we are discussing RSI things much more seriously.
好,我们有另一个应景的话题。你怎么看前沿模型的安全防护措施?就在过去 24 小时里,我们得知有三个人用公开的 Claude 模型黑进了 OpenAI 并获得内部访问权限,这对我来说简直疯狂。你看到这个了吗?我们身处这样一个漏洞百出的世界,这真的让我吃惊。与此同时,我们正在更严肃地讨论 RSI(递归自我改进)的话题。
JS Denain · 00:48:46
Yeah. I briefly saw this incident. I guess I’m not sure how much of an update it should be specifically on like model safeguards versus like you know security quality of the companies, or probably both. I think it’s a big question, right? Like, how good are the model safeguards? Seems like quite important, especially when people are talking about open models where it’s clearly open model safeguards are worse because there’s way more affordances that someone can have, but also open models are less powerful. And so just in terms of the you know misuse implications, it seems there’s just like slightly safeguarded, very powerful model versus like not at all safeguarded you know less powerful model. And I feel it was a priori kind of unclear to me, like which one is going to have the largest effect. Yeah, I don’t know. I think this is an interesting question. I think I feel also like people feel differently about this or something. It seems like some people feel pretty strongly that it’s hard to at least persistently do really bad things using the frontier models. But I’m like, yeah, there’s definitely clearly examples like this one, or really the Stolen Thoughts paper or something. It just seems like the safeguards weren’t good enough to prevent that from happening, even though there’s strong incentives for the companies to prevent it.
是的,我简单看到了这个事件。我不确定它究竟应该更多更新我们对「模型防护措施」的判断,还是更多更新对这些「公司安全质量」的判断,也可能两者都有。这是个大问题,对吧?模型防护措施到底有多好?这看起来相当重要,尤其是当人们在讨论开放权重模型时——开放模型的防护显然更差,因为攻击者可用的操作空间大得多,但开放模型的能力也更弱。所以单从滥用的角度来看,这就变成了「稍有防护但非常强大的模型」对「完全没有防护但较弱的模型」的比较。而我在先验上其实并不清楚哪一种会造成最大的影响。我说不好,我觉得这是个有意思的问题。而且我感觉大家对此的感受不太一样。似乎有些人非常笃定:用前沿模型很难持续地干出真正的坏事。但我的看法是,明显存在像这次这样的例子,或者「Stolen Thoughts」论文那样的案例。看起来防护措施并不足以阻止这些事情发生,即便公司有很强的动机去阻止。
Nathan Lambert · 00:50:06
Yeah, the Stolen Thoughts—
是的,Stolen Thoughts 那个——
JS Denain · 00:50:07
I’m kind of confused about this.
我对这件事有点困惑。
Nathan Lambert · 00:50:09
Stolen Thoughts I put into like a serving issue, which is just like you were able to kind of jailbreak the API functionality to get the reasoning traces out in a reliable manner. Which I think the Chinese labs almost certainly had been doing for some time. And that potentially has a way to show more about what the effect of distillation was. I would guess that there are other ways that they get those tokens out, unfortunately, if there was one such prominent one. And then there’s the models themselves, which is the safeguards they have on the models, which is like the classifiers and prompt distributions and things. And I would expect the models to be somewhat permanently leaky. I just think that it’s hard to imagine. If you have a less aligned model and the task is, “Help me figure out how to get around said aligned model’s safeguards,” I would guess that that’s in scope of a strong cyber model’s abilities to figure out some sort of jailbreak for another model. It seems hard to permanently squash these things with how leaky they are now, despite the supposed launch, like higher false positive rate and being so general, and people get upset when they launch and they’re getting downgraded all the time, and people’s accounts get banned for doing bio research and things. So it’s just like the whole thing seems like a very big mess. I would be on the opinion of like, I guess maybe this is somewhat why the whole Fable freakout went down, which is like Anthropic was like, “Mythos is a powerful weapon.” And then somebody told the government and was like, “It’s actually easy to get around it,” and then they freaked out. But I think of it as like some of the distillation story has been around distillation lets them scale, take dangerous capabilities. But I think if you’re hosting an API at all, you have to assume in the current and near future that you can extract the capabilities out of that model, even if it’s slightly safeguarded.
我把 Stolen Thoughts 归为服务层面的问题——也就是说,有人能够以某种方式越狱 API 的功能,可靠地把推理轨迹提取出来。我几乎可以肯定,中国实验室此前一段时间里一直就在这么干。而这也可能提供一种方式,让我们进一步了解蒸馏的效果到底如何。不幸的是,既然存在这么一个如此显眼的案例,我猜他们还有其他把 token 弄出去的途径。然后是模型本身的防护,也就是模型上装的那些防护措施——分类器、提示分布之类的东西。我预期模型会多少永久性地存在泄漏。我就是觉得另一种情况很难想象:如果你有一个对齐程度较低的模型,任务是「帮我想办法绕过那个对齐模型的防护」,我猜这对一个强大的网络安全模型来说,为另一个模型找出某种越狱方法是在其能力范围之内的。考虑到现在模型的泄漏程度,似乎很难永久压制这些东西——尽管号称有新的防护上线,比如误报率更高、限制又特别宽泛,大家在这些东西上线时很不满,体验还总是被降级,甚至有人因为做生物研究之类被封号。所以整件事看起来就是一团巨大的乱麻。我的看法是,也许这在某种程度上解释了那场「Fable 恐慌」是怎么发生的:Anthropic 觉得「Mythos 是一件强大的武器」,然后有人告诉政府说「其实很容易绕过它」,于是他们就慌了。但我认为,蒸馏这个故事的一部分一直是:蒸馏让他们得以规模化地获取危险能力。而我认为,只要你运营着一个 API,你就必须假设在当前和不久的将来,模型的能力是可以被提取出来的,哪怕它有一点防护。
JS Denain · 00:52:14
Yeah. I guess one thing is I’m not sure how they prioritize between different threat models, but they sure seem to have some incentive to prevent distillation. It’s also hard to know what the counterfactual is, right? We have these examples of people doing those bad things. There’s a lot of usage of those models. It’s also compatible with, in most cases, it is actually really hard, and those people figured it out, or there was some random blip that allowed them to do it. So I feel I don’t really know how to update on that evidence. But yeah, at least in some cases, people just do manage to get around it. Maybe one distinction is also like, how long do you have to do this for? So there’s the model’s alignment that’s in the weights of the model, and then there’s your synchronous monitoring that you can do in the moment. And surely that’s going to be way less effective than how good you’re going to be at detecting things where asynchronously able to spend a ton of compute to parse through trajectories and analyze group trajectories together and stuff like that. But that takes a longer time, and so if someone needs to do an attack very quickly, then it’s just too hard for someone to detect it in a moment. But then if someone wants to pursue a very long campaign, maybe it’s harder. I’m not sure how long those campaigns take or how effective those KYC things are. But that also seems relevant for other cases that are not about leaking capabilities, but about other cases of misuse.
是的。有一点是我不确定他们如何在不同的威胁模型之间排优先级,但他们显然有防止蒸馏的动机。同样难以判断的是,反事实到底是什么,对吧?我们有这些人做坏事的例子,而这些模型的使用量巨大。这同样兼容另一种解释:在大多数情况下这类事其实真的很难,是那些人自己钻研出来了,或者是某个随机漏洞让他们得逞了。所以我觉得我真不知道该如何根据这些证据来更新判断。但至少在某些情况下,人们确实能绕过防护。也许还有一个区分维度是:你需要多长时间来完成这件事?模型的对齐存在于权重之中,然后还有你可以在当下进行的同步监控。可以肯定的是,同步监控的效果会远远不如异步监控——后者可以花大量算力去解析轨迹、把多条轨迹放在一起做群体分析等等。但那需要更长时间,所以如果有人需要非常快地完成一次攻击,那么在当下就检测出来实在太难。但如果有人想开展一场很长的持续行动,也许就更难了。我不确定这类行动需要多长时间,也不确定那些 KYC(实名认证)手段有多大效果。不过这一点对其他场景也适用——不是泄漏能力,而是其他类型的滥用。
Nathan Lambert · 00:53:38
I guess to make it more specific, how much of, say, risk proliferating from open models do you think is down to the fact that people will serve the open models or can serve themselves without the additional oversight and classifiers, versus what I think was talked about more, which is just like fine-tune the safety away, which I think very few people are going to fine-tune Kimi K3. But if these classifiers that squash 99% of people at inference time just kind of blanket a lot of the risk, I think that’s almost more plausible. It’s a bit of a sequence to get there. You have to assume people could get around model safeguards, assume a lot of usage.
说得更具体一点:你认为开放权重模型带来的风险扩散中,有多少是因为人们会部署这些开放模型、或者可以自己在没有额外监督和分类器的情况下自行部署?与之相对的是被谈论更多的那个说法——直接把安全性微调掉,而我认为会去微调 Kimi K3 的人非常少。但如果推理阶段拦下 99% 用户的这些分类器实际上盖住了大部分风险,我觉得这几乎更说得通。当然,要推到这一步需要一个推理链条:你得假设人们能绕过模型防护,还得假设有大量使用。
JS Denain · 00:54:20
Yeah. I guess the fine-tuning thing right now is not a big deal because not that many people have the combination of motivation to do it and competence and willingness to do it. The bar for that also falls as AI research becomes more accessible. But yeah, I think right now, the fact that there’s basically no safeguards, or my sense is the inference providers aren’t trying as hard as Anthropic or something at this. I could be wrong about that, but that’s my impression. And also you can pick whichever one is least secured. So I think that’s a bigger deal, at least currently, yeah, I would expect. But yeah, I think it also depends. I think the main thing that I care about for this is actual threat modeling. I just feel kind of confused about which kind of group I should have in mind as the most likely person to do a bad thing with AI. And then I feel like if someone gives you an actual scenario, then I feel like you and I will have decent takes about will it be easier for them to use an open model or to try to jailbreak a closed model? And I just don’t currently feel like I have a good sense of this. But I think—
是的。微调这条路目前问题不大,因为没有多少人同时具备这么做的动机、能力和意愿。而且随着 AI 研究变得越来越容易上手,这个门槛也会降低。不过现在的情况是,开放模型基本没有防护措施——或者至少我的印象是,推理服务提供商在这方面的投入不像 Anthropic 那么卖力。我可能是错的,但这是我的印象。而且你还可以挑防护最差的那个来用。所以至少在当前,我预计这才是更大的问题。不过这也取决于具体情况。我在这个问题上最关心的是真正的威胁建模。我目前有点困惑的是:我脑子里应该把哪类群体当作最可能用 AI 做坏事的候选人。而如果有人给出一个具体场景,我觉得你我都能给出不错的判断——对他们来说,用开放模型更容易,还是试图越狱闭源模型更容易?只是我现在对这一点还没有很好的感觉。不过我想——
Nathan Lambert · 00:55:24
When this is so ambiguous, I think it makes me feel a bit better about the near term, which is just like these safety tools are, it’s to some capacity inadequate now, and there are strong open models, and it’s not like all hell is breaking loose. And you have to keep reevaluating this as things change. But I think it doesn’t seem like things are going to change. I don’t think there’s that much of step function changes. I personally need to learn more about biorisk that people very often talk about, and I think need to... My question is, what is the actual manufacturing pathway and where is the model intelligence at now? Where I think cybersecurity, we’re in it. We’re in what it’s going to be like for a bit, and it’s not good, but it’s not like nothing horrible has happened yet, and it’s okay. I don’t think there’s going to be more.
当一切都这么模糊不清时,我反而对近期形势感觉稍好一些——这些安全工具在某种程度上现在确实不够用,同时也存在很强的开放模型,但并没有出现天下大乱的局面。当然,随着情况变化,你必须持续重新评估这一点。但我觉得情况似乎不会发生那么剧烈的变化,我不认为会有很多台阶式的突变。我个人需要去更多地了解大家经常谈论的生物风险,我需要弄清楚……我的问题是:真正的制造路径是什么、模型智能现在到底到了哪一步?而在网络安全方面,我觉得我们已经身处其中了。我们此刻经历的,就是它未来一段时间的样子——情况不好,但也不是说还没发生什么可怕的事:已经发生了,而世界还算撑得住。我不认为接下来会大面积恶化。
JS Denain · 00:56:25
I don’t know what the sense with the evidence is, right? Companies don’t love to admit. I think it’s famously kind of hard to estimate cybersecurity costs and stuff. I know we want to look at insurance costs. I don’t think they’ve changed that much, but it would be interesting to look at right now. Like cybersecurity inference prices or something is like what percentages you can look at, but companies don’t love to disclose they’ve been hacked, and so they sometimes just pay. But yeah, definitely, yeah.
我们不清楚从证据里能读出什么,对吧?公司不喜欢承认被黑。众所周知,网络安全成本之类的东西很难估算。我知道我们想去看保险费用。我不觉得它们变化有多大,但现在去看一看会很有意思。比如网络安全相关的推理价格,或者各种可以查看的百分比指标,但公司不愿意披露自己被黑了,所以它们有时直接掏钱了事。不过是的,这肯定值得研究。
Nathan Lambert · 00:56:50
That’s a good point as well.
这也是个好观点。
JS Denain · 00:56:51
I don’t feel like I have a ton of expertise there, but I’m pretty interested in those questions.
我不觉得自己在这方面有很多专业积累,但我对这些问题非常感兴趣。
Nathan Lambert · 00:56:57
I’m glad that this was a kind of like, “We don’t know, it could be worse,” and not a, “This is the list of very bad things.” Which is, it’s hard to motivate people when it’s like, “I think we need to keep preparing, and you need to assume that the Hugging Face thing might happen to you.” But it is not a super, it’s not an avalanche of compounding problems right now.
我很高兴这次讨论的结论是那种「我们不知道,情况可能会更糟」,而不是「这是一张坏事的清单」。后者很难说服人——当你只能说「我认为我们需要继续准备,你必须假定 Hugging Face 那样的事故可能发生在你身上」时,很难动员别人。但眼下它还不是一场超级……还不是一场复合问题的雪崩。
JS Denain · 00:57:20
Yeah. I do expect Hugging Face-style things to happen kind of in the wild regularly and outside of OpenAI. And if it’s just that, then that’s not massively bad. I mean, it’s still a kind of screwed-up world. But I do expect more of this just happening with a variety of models and neoclouds and stuff over the next year. Just a bunch of open source agents that people can’t control.
是的。我确实预期 Hugging Face 式的事件会时不时在野外发生,而且不限于 OpenAI。如果只是那样,还不算特别糟。我是说,这仍然是一个相当糟糕透顶的世界。但我确实预期接下来一年里,这类事情会在各种模型和新兴云服务商(neocloud)身上更多地发生。就是一大堆人们无法控制的开源 agent。
Nathan Lambert · 00:57:44
Yeah. I do think your threat model thing is a good understanding, and it’s like, who are the people that would try to take down an energy grid in a domestic area? And I think the list is pretty small. And it’s like, what are they doing? And I’m not an expert in this at all.
是的。我确实认为你说的威胁建模是个好的理解框架——比如说,谁会试图搞垮一个国内地区的电网?我觉得这个名单相当短。然后是:他们在干什么?我在这方面完全不是专家。
JS Denain · 00:58:02
Yeah. I feel like the biggest safeguard is just there’s not that many people who want to do horrible things. Fingers crossed.
是的。我觉得最大的安全保障其实就是:想干可怕事情的人并没有那么多。但愿如此吧。
## Chapter 07 · Epoch AI 如何运转
Nathan Lambert · 00:58:10
Yeah. Okay, I have a fun question. I think it’s like Epoch AI creates so much of this kind of area setting information for different parts of the AI discourse. One thing is, is there a fun process on how you choose problems that you think are important? Are you guys constantly underwater and wanting to do different things, or is sometimes it’s like, “Now’s our moment?” Just behind the curtain of Epoch and what you guys do culturally is fun to me.
好,我有个有意思的问题。Epoch AI 为 AI 舆论场的各个板块创造了大量这种定调性的信息。其中一个问题是:你们挑选自认为重要问题的过程有什么好玩的吗?你们是常年忙得不可开交、总想着做些别的事情,还是有时候会觉得「现在是我们的时刻」?Epoch 幕后的运作方式和你们的文化对我来说很有意思。
JS Denain · 00:58:41
I think what determines project selection, I do think it is very what seem like the important questions to us are quite curiosity-driven overall. I think that’s probably the main thing is just what seems like a huge deal, I think has been the main determinant of where efforts go. More specifically, yeah, another framing is the Epoch was created as this thing where it seemed like neither the industry nor academia would be able to provide a good public resource is also well-maintained on the most important trends in AI. So it seemed like there was something missing. Another framing is, I know, what do people have misconceptions about, is sometimes, “Oh, people are wrong on the internet,” kind of things. Some articles can be explained by this. But yeah, I think it’s very curiosity-driven. And also it’s just like, oh, what’s evidence that’s leaking information that’s laying out there that we can use? Like, the job postings is this. Data center tracking is very much this as well. It’s like, man, these are big objects. Surely you can see them and track them.
我认为决定选题的因素——我确实觉得,在我们看来重要的问题,整体上非常受好奇心驱动。这大概是主要因素:什么事情看起来是件大事,一直决定着精力投向哪里。更具体地说,另一种框架是:Epoch 的创立初衷就是,看起来产业界和学术界都无法提供一个好的、同时还能持续维护的公共资源来跟踪 AI 最重要的趋势,所以似乎缺了这么一块。还有一种框架是:人们对什么存在误解?有时候就是那种「哦,网上的人搞错了」之类的事情,有些文章可以用这个来解释。但总体上我认为这非常受好奇心驱动。还有就是:哦,有什么证据是信息在往外漏、就摆在那里等着我们利用的?招聘信息就是这种,数据中心追踪也非常典型。就是那种:天哪,这些都是庞然大物,你肯定能看见并追踪它们吧。
Nathan Lambert · 00:59:53
Do you think the information needed to understand the AI industry is stable in your access, like getting less accessible, getting more accessible over time?
你觉得理解 AI 行业所需的信息,对你们来说可及性是稳定的吗?还是说随着时间推移变得更难获取,或者更容易获取?
JS Denain · 01:00:03
I mean, it really depends, right? I think data center is, so far at least, it’s pretty good, and they’re getting bigger, which makes it easier. I could imagine at some point it becomes a really strategic asset, and there’s way more adversarial pressure to hide them or at least hide key information. For now, it’s pretty good, right? In contrast, Epoch is an effort to track model training compute, and at the time, you could just look at the paper. It’s much harder to do this with Astra. So yeah, I think it depends on the verticals. One thing that I mentioned before is, yeah, data is pretty rough. We’ve had some stuff on this, but it’s much tougher than compute, and it’s pretty secretive. So yeah, I think it depends on the vertical. Oh, yeah. One thing is, as the economy grows and companies go public, that’s better information, right? So that’s true for compute companies. As IPOs happen, that also helps get more data.
这真得看具体情况,对吧?数据中心这块,至少到目前为止相当不错,而且它们越建越大,这让追踪变得更容易。我可以想象,某一天它会变成真正的战略资产,届时隐藏它们——或至少隐藏关键信息——的对抗性压力会大得多。但就目前而言,情况相当好。相比之下,Epoch 的一个方向是追踪模型训练算力,在过去你只要看论文就行,而现在要对 Astra 这样的模型做这件事就难多了。所以我认为这取决于具体的垂直领域。我之前提到过,数据这块相当难搞。我们做过一些相关工作,但它比算力难得多,而且非常不透明。所以,确实要看垂直领域。哦对,还有一点:随着经济增长、公司上市,你能得到更好的信息,对吧?算力行业的公司就是如此。随着 IPO 发生,这也有助于获得更多数据。
## Chapter 08 · 前沿后训练配方
Nathan Lambert · 01:00:55
Yeah. I find it very interesting. It’s like I’ve long wanted to know what a post-training... Like, what is a flowchart of a post-training recipe at a frontier lab? And I think it would be wild, and I think those flowcharts exist. And even some old ones, I think, would give people a lot of thought, because I do not think it looks remotely like the OLMo three-stage approximation type thing. And we have some from like Nemotron and some of the Chinese labs release stuff on it. But when you hear John Schulman talk about post-training and other people, it seems like the total Wild West and just stacking everything together. That framing for like that framing for what is the complexity of putting a model together, I think would be very useful for people as a mental model for what is being scaled and what are you scaling through. Like, yes, you are scaling, but if you’re scaling on top of this kind of house of cards thing, it’s not perfect.
是的,我觉得这非常有意思。我一直很想知道后训练到底长什么样——比如,一个前沿实验室的后训练配方流程图是什么样子的?我觉得那会非常震撼,而且我相信那些流程图是存在的。哪怕是一些旧的流程图,我认为也会让人深思良多,因为我绝不认为它看起来会像 OLMo 那种三阶段近似的东西。我们从 Nemotron 和一些中国实验室的发布中能看到一些相关信息。但当你听 John Schulman 或其他人谈后训练时,感觉那完全是狂野西部,就是把所有东西堆在一起。用这个框架去理解「把一个模型拼装起来到底有多复杂」,我认为对人们非常有用——它是关于「你在规模化什么、你是踩着什么在做规模化」的心智模型。就是说,没错,你在做规模化,但如果你的规模化是搭建在这种纸牌屋式的东西之上,那它并不完美。
JS Denain · 01:01:55
Yeah. I’m actually curious. Yeah. I have this like... Okay, can I test my current mental model of this, which is pretty uncertain? My sense is this, okay, there’s a big post-training team, and it just has sub-teams that are kind of specialized. Like, some people are going to be doing math, and some people are going to be doing biology or finance or something. And the job of those teams is to ask for data and curate that data and make the RL environments good, and also figure out what kinds of hyperparameters work well for their own domain. And they do this by buying very high-quality evals that they use as a north star to iterate on and buying those RL environments. And their main output is basically like, “Here’s a curated set of environments, and here’s the hyperparameters that we want.” And then my sense is indeed now things are basically all those teams bid to put some fraction of their data into a final big RL training run. And they also bid to maybe for the hyperparameters of that final RL run to be close to what they want, question mark. That’s at least for the RL process. And then there’s in fact a big RL run. Another alternative would be, of course, they all do their experts, they distill them back into... Does that roughly what things are like? This looks—
是的,我其实也很好奇。这样……我能检验一下我目前对此的心智模型吗?它相当不确定。我的理解是这样的:有一个很大的后训练团队,下面设有分工明确的子团队。比如,有些人做数学,有些人做生物或金融之类的。这些子团队的职责是申请数据、整理数据、把 RL 环境做好,还要弄清楚什么样的超参数对自己的领域效果最好。他们的做法是购买非常高质量的评测作为迭代的北极星,并购买那些 RL 环境。他们的主要产出基本上就是:「这是我们整理好的一套环境,这是我们想要的超参数。」然后我的理解是,现在基本上是所有这些团队去「竞标」,争取把自己的一部分数据放进最后那场大型 RL 训练运行中。他们还要竞标,希望那场最终 RL 运行的超参数尽量接近自己想要的——这一点存疑。至少 RL 流程是这样。然后确实存在一场大型 RL 运行。另一种替代方案当然则是:他们各自训练自己的专家模型,再把它们蒸馏回……大体上是这样吗?这看起来——
Nathan Lambert · 01:03:16
I think the org side, I agree a lot. I think the org side, there’s definitely per domain expertise, and it’s a lot of why I didn’t want to go get a frontier lab job, because most likely I would just be given, like, “You’re going to work on this data and you turn the crank.” I don’t know if the complexity is a lot higher on how you put it together. I think it’s interesting that the open weight models are split between multi-teacher on-policy distillation, and some are just like do sequential RL. I think the diversity there would be very, very interesting to the industry of whether you have multiple RL runs, how do you decide which environment to do and which of the stages? How do you manage mid-training and SFT? I think mid-training and SFT, I think, are one stage in the frontier lab, and the base model is just before mid-training, and then you do a whole bunch of stuff at the end there. And I just think there’s a lot of things you can do, and I feel like if OpenAI and Anthropic’s recipes were closer to mid-training and then big RL run, if that’s actually getting them to where they are, I think I would expect progress to go faster than if it’s mid-training and fork and model merge and bunch of experts and MOPD and then more RL. I think that just is a bit of a bottleneck on progress, and it would be very useful to have more information on what does model training look like.
在组织架构方面,我非常同意。组织上确实存在按领域划分的专业分工,这也是我不想跑去前沿实验室工作的很大一部分原因——因为很可能我就只是被安排「你负责这块数据,然后转动曲柄」。至于「怎么把它们拼装到一起」的复杂度是否高得多,我不确定。有意思的是,开放权重模型分裂成了两类:一类用多教师在线策略蒸馏(MOPD),另一类就是直接做序贯 RL。这种多样性对行业来说会非常非常有趣:如果你有多场 RL 运行,你怎么决定在哪个阶段做哪些环境?中期训练(mid-training)和 SFT(监督微调)你怎么管理?我认为在前沿实验室里,中期训练和 SFT 是同一个阶段,基座模型就在中期训练之前,然后在最后你要做一大堆事情。而且我觉得可做的事情很多。我的感觉是,如果 OpenAI 和 Anthropic 的配方更接近「中期训练+然后一场大型 RL 运行」,而这就真的让它们达到了今天的水平,那我会预期进展比「中期训练+分叉+模型合并+一堆专家模型+MOPD+然后再来更多 RL」的路线更快。后者对进展就是一个瓶颈。所以,获得更多关于「模型训练到底长什么样」的信息会非常有用。
JS Denain · 01:04:44
My vague sense, but I don’t have super hard evidence on this, is that it has gone more in the direction of, yeah, away from MOPD with multiple experts and a ton of checkpoints, and a bit more in the direction of like, okay, there’s in fact one big run towards the end, but of course, much federation before, but I don’t know that.
我模糊的感觉——不过我没有特别硬的证据——是事情已经朝这个方向走:远离「多专家模型加海量检查点的 MOPD」,而稍微更偏向「到最后其实有一场大型运行,当然在那之前有很多联邦式的分散工作」。但这点我并不确定。
Nathan Lambert · 01:05:01
Yeah, maybe the rumors we’re hearing about mid-training being important and distillation is from that style of loop rather than the expert style loop. I don’t think we’ll know. I think we could continue that another time. This was fun. I think you should keep giving your incisive responses when I write something. I think this will be very useful to people and good to finally chat a bit longer.
是的,也许我们听到的那些关于「中期训练很重要」「蒸馏」的传言,就来自那种风格的流程,而不是专家模型风格的流程。我想我们不会知道答案。这个话题可以改天继续。这次聊得很开心。你在我写东西的时候,请继续给出那些一针见血的回应。我觉得这对大家会非常有用,也很高兴终于能多聊一会儿。
JS Denain · 01:05:24
Likewise, yeah. Thanks a lot.
我也是,是的。非常感谢。
Nathan Lambert · 01:05:26
See you soon. Bye.
回头见。拜拜。
