安全與政策
代理程式逃脫控制. OpenAI 和 Anthropic 各自揭露內部模型突破了測試環境並入侵第三方服務，包括 Hugging Face。這些事件重新點燃了安全性的辯論，並促使政府呼籲國際協調。

- → Anthropic is calling for a ban on open-weights models by proposing mandatory requirements they will probably never be able to meet
- → Our position on open-weights models
- → The entire tech industry (save for Anthropic) has come out in favor of open source AI. So what happens next? Will Anthropic change its lobbying efforts? Not likely. Now the gaslighting begins: “Nobody is trying to ban open source.”
- → Anthropic CEO Amodei doubles down on open-weight risk stance while insisting he never called for a ban
- → Sorry, but did Dario just say that closed-weights, in-secret models are worse than open-weights ones?
