Anthropic 应美国政府要求暂停 Fable 和 Mythos 模型

政府援引安全报告称 Fable 存在 jailbreak 风险，但 Anthropic 对此表示异议，认为行动缺乏透明和公正。Axios 消息称双方存在严重沟通障碍，政府曾给予 Anthropic 仅 90 分钟回应时间。

数十名安全研究人员和行业人士签署公开信，呼吁恢复模型并建立透明的 AI 风险评估流程。

Anthropic, the U.S. government, and the Mythos/Fable shutdown - a roundup of the latest news: - Senior Anthropic staff are reportedly meeting with government officials in Washington today to try and diffuse the situation - Axios sources framing the issue as a communication breakdown: " "Anthropic has not done a great job at trying to speak to the administration and appreciate the ideological differences," one source familiar with the administration's thinking said. "It's like they just speak in different languages," the source said, adding that the company has simply not figured out how to communicate with this administration. - The Washington Post sources dispute the government's stance that CEO Dario Amodei refused to work with them on the safety issue, and were given just 90 minutes to comply with the order. “Dario agreed to fix the problem if it was real, but they were never given anything until people started flagging this Amazon report,” one of the people said. - Security researchers disagree with Trump admin on the alleged Fable jailbreak risk. An open letter from titled "On Transparent AI Cyber Protections" details why Fable should be restored: "We, the undersigned executives and technical leaders from across the United States and its allies, write to you to ask you to lift the export control directives on Anthropic’s Fable and Mythos large language models and commit to an open, scientific and transparent process of handling AI risk assessments in the future." Currently signed by dozens of researchers and industry members. The Rundown AI @TheRundownAI Wow - Anthropic is suspending all access to Fable and Mythos after the U.S. government's export control directive. The government designation would restrict access to any foreign national (even those in the country). The government cited reports of Fable jailbreaking in the order, which Anthropic appears to disagree with. "We believe the government should have the ability to block unsafe deployments, as part of a statutory process that is transparent, fair, clear, and grounded in technical facts. This action does not adhere to those principles." 🔗 View Quoted Tweet📊 5 ⚡
