AnthropicがClaude Fable 5/Mythos 5に導入した新たな「不可視の介入」について報告。競合するLLM開発（プリトレーニングパイプライン、分散トレーニングインフラ、MLアクセラレータ設計など）に関するリクエストに対し、ユーザーに知らせることなくモデルの応答を制限する仕組み。同社は～0.03%のトラフィックに影響するとしているが、研究コミュニティから広範な批判を受け、後にこの方針を撤回した。
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.
