# AI 公开信浪潮：开源权重、蒸馏与前沿AI发展速度之争

## AI 点评

> 这波公开信交锋很值得跟进：它不只是政策辩论，更暴露了AI巨头之间的路线撕裂——微软和OpenAI在拥抱开源权重，Anthropic却成了“减速派”旗手。对于做开源模型、用蒸馏训练或者指望AI自治的企业，这场博弈的结果会直接改写游戏规则，建议尽早研读原始信件并评估自身立场。

## 速览

过去几周，AI 领域接连出现多封重磅公开信。微软牵头、235家机构签署的公开信支持开源权重模型，并罕见地为蒸馏技术辩护；Anthropic 则强调开源权重可能被威权政府滥用，呼吁打击工业级蒸馏。7月28日，1300多名前沿AI公司员工联合发布公开信，要求美国政府支持国际合作，主动为自动化AI研发设定节奏。随着Claude Code、OpenAI Sol、Kimi K3等AI自主改进案例出现，业界对AI发展失控的担忧正显著升温。

## 关键点

- 微软牵头的公开信获235家机构签署，包括NVIDIA、亚马逊、YC、Linux基金会，OpenAI后补签，明确支持开源权重模型并辩护蒸馏技术。
- Anthropic 反应冷淡，CEO Dario Amodei 称从未主张封禁开源权重，但强调其风险并呼吁打击工业级蒸馏。
- 7月28日，1324名前沿AI公司员工联名信要求美国政府主导国际合作，为自动化AI研发设置节奏。
- Anthropic 80%代码由Claude Code产出，OpenAI Sol降低20%服务成本，Kimi K3自行设计芯片，成为AI自我进化风险的具体例证。

## 全文

Open letters about AI development I wrote this summary of the past few weeks of open letters as a section of my sponsors-only newsletter but I've decided to share it here as well. Open Weights and American AI Leadership was shepherded by Microsoft, dated July 24th, and signed by 235 AI-adjacent companies including NVIDIA, Amazon, Y Combinator, The Linux Foundation and (a later signer) OpenAI. It's clearly an argument designed to counter any instincts by the current US government to ban or limit open weight models over "safety" concerns - a reasonable consideration given what happened to Claude Fable 5! Relying solely on closed models is not inherently safe: they can be breached, misused, or fail in ways that outsiders cannot detect. And concentrating advanced AI capabilities behind a small number of closed models compounds that risk. It results in a small number of single points of failure, weakens competition, and leaves critical technology in the hands of a few providers. Open weight models, on the other hand, allow a broad community of researchers and developers to examine their behavior, identify vulnerabilities, develop safeguards, and improve them over time. The one surprising note in the letter is that it comes out in support of distillation, where models train on output from other models: In shaping this ecosystem, policymakers should be careful not to conflate legitimate model-development techniques with misappropriation. Distillation, or the practice of using one model’s outputs to help train or improve another, is a widely used technique for model improvement, evaluation, and validation. It reflects a long tradition of learning from, building upon, and improving existing technologies, a tradition that has helped drive innovation since the rise of the open-source software movement. Notably absent from the signatures: Anthropic, who published their own response Our position on open-weights models three days later. CEO Dario Amodei doubled down on the risk of authoritarian governments building "AI models that are more powerful than those built by the US", and models being "misused to carry out cyberattacks or biological attacks", and called for "a crack down on industrial-scale distillation operations", while also stating that "Anthropic has never advocated for a ban on open-weights models". Then on July 28th Pacing the Frontier was published, featuring signatures from "1,324 employees of frontier AI companies" - with names like Jakub Pachocki (Chief Scientist, OpenAI), Ilya Sutskever (Safe Superintelligence Inc, previously OpenAI), Dario Amodei (Anthropic), Jack Clark (Anthropic) and more. Their core message: We request that the U.S. government support an international effort to develop the technical and governance tools needed to deliberately pace the frontier of automated AI development. Their concern is intense competitive pressure combined with accelerated AI progress caused by automated AI research - and given that Anthropic produce 80% of their code with Claude Code, OpenAI had Sol reduce their end-to-end serving costs by 20%, and Kimi K3 designed a chip to serve a nano model built on its own architecture, you can see why people are taking that risk more seriously right now.
