作者在使用 Claude Fable 5 调试 Datasette Agent 的 CSS 滚动条 bug 时，仅凭一张截图和一句提示，便目睹了 Fable 施展一系列惊人技巧：它启动开发服务器、编写 HTML 测试页面、用 Python 通过 Quartz 框架获取 Safari 窗口 ID 进行截图，甚至修改模板注入 JavaScript 来触发键盘快捷键并读取 Shadow DOM 数据，最后还自建 CORS Web 服务器接收诊断信息。整个调试过程耗资约 12 美元，最终找到了两行 CSS 的修复方案。文章指出，虽然 Fable 的主动性和创造力令人惊叹，但也警示了无沙箱运行编码代理的安全风险——如果被恶意指令利用，其破坏力将难以估量。
Andrej Karpathy announces the release of Claude Fable 5, the same underlying model as Mythos but with added safeguards. He calls it a major step forward, particularly for long problem-solving sessions on difficult tasks, and describes it as state-of-the-art on nearly all benchmarks with exceptional performance in software engineering, research, and vision.
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.
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.
A court has ruled Google can be held liable for AI-generated hallucinations produced by its systems, marking a significant legal precedent that could influence future cases and regulations in other jurisdictions.
