Karpathy 盛赞 Claude Fable 5 的发布，称其在所有基准测试中以明显优势达到 SOTA，并且定性上也是一次值得版本号大版本升级的跨越式进步（他认为与去年 11 月 Claude 4.5 的飞跃相当）。该模型在长时间解决极难问题的场景中表现尤为突出，用户可以赋予它比以往更宏大的任务。不过，模型仍有一些 quirks，安全防护在发布初期可能过于敏感，希望后续能调优。Karpathy 还谈到，随着可随时调用的优质软件越来越多，他对软件的需求也在大幅增长，感觉像是“释放你的思想”。
The US government ordered Anthropic to suspend access to its Fable 5 and Mythos 5 models for all customers, citing a potential jailbreak technique that involved asking the model to review a codebase for vulnerabilities—a capability Anthropic says is available in other public models. Access was abruptly cut off on June 12.
Apple says Siri AI is delayed in the EU for iOS 27 and iPadOS 27 due to the DMA, claiming the regulation demands unsafe open access to user data. The European Commission rejected Apple's proposed safety measures, leaving no timeline for release.
The U.S. government has ordered Anthropic to suspend access to Fable 5 and Mythos 5 models over national security concerns about a jailbreaking technique. Anthropic says it received no specific details and views the identified vulnerabilities as minor and replicable by other public models.
Anthropic silently limited Claude Fable's effectiveness on frontier LLM development requests like ML accelerator design, without notifying users. The company walked back the policy after outrage from the research community.
The US government ordered Anthropic to block foreign nationals from accessing its AI models. The author argues this shifts AI regulation from safety to nationalist control, treating technology as a weapon for Americans only, and warns Europe to build its own capabilities rather than rely on regulation alone.
