Claude Fable 5终于回归了，加了新安全机制，暂时部分编程功能会降级到Opus 4.8，值得关注后续。
Anthropic宣布Claude Fable 5将于明日全球恢复使用。在与美国政府对话后，模型新增了针对网络安全任务的分类器。短期内部分编码和调试任务将回退至Opus 4.8。Anthropic正与Amazon、Microsoft、Google等合作起草评估AI越狱的共识框架，并扩大与政府的模型测试协作。

Claude Fable 5 will be available again globally tomorrow. After a series of productive conversations with the US government, we're redeploying the model with a new set of classifiers to target and block more cybersecurity tasks. In the near term, some routine tasks like coding and debugging will fall back to Opus 4.8. We’ll continue to refine these classifiers over the coming weeks to reduce false positives and better distinguish genuine misuse from legitimate requests. We’ve also begun drafting a consensus framework—with Amazon, Microsoft, Google, and other Glasswing partners—for assessing the severity of AI jailbreaks and how AI developers should respond to them. We invite other industry partners and model providers to join us in this effort. Finally, we’re scaling up our collaboration with the US government on model testing and safeguards. This will include pre-release access to models and safeguards for evaluation, information sharing on jailbreaks and misuse, and dedicated resources for joint research. Thank you to our users for your patience, and to our partners across the government, industry, and the research community who worked alongside us to make Fable 5 available again.
