WSJ：OpenAI 以泄露调查为由解雇 3 名安全研究员
OpenAI 解雇 3 名安全研究员，起因是 Astra 模型设计被报道泄露，具体细节挺少见的。
据 WSJ 报道，OpenAI 安全人员在调查中发现外部安全研究员与内部人员的 Signal 聊天记录被删除，随后解雇了 3 名安全研究员。调查起因是 9 月有报道称 OpenAI 新模型 Astra 采用新方法提升智能但减少了思维链的记录。OpenAI 将该报道视为模型设计的机密泄露，并开始追查信源。调查人员将曾协助 METR 分析 7 月 Hugging Face 攻击日志的 Ryan Greenblatt 列为疑似泄密者，他本人否认。
WSJ: OpenAI fired 3 safety researchers after security staff found disappearing Signal chats with an outside safety researcher.
The phone checks started after a September news report said OpenAI’s newest model, Astra, uses a new method that makes it smarter but writes down less of its thinking, so humans can see less of how it reaches answers. so the concern was, if future models think without writing those steps down, as the researchers feared Astra-style designs might, investigators would see only what the agents did, not why.
OpenAI treated that report as a leak of its secret model design and began hunting for the source.
Investigators named Ryan Greenblatt, who helped METR analyse logs from July’s Hugging Face hack, as the suspected leaker; he denies it.
