Anthropic deploys Claude Sonnet 5, Fable and Mythos restored
AI-summarised brief · reviewed before publication
Anthropic has deployed Claude Sonnet 5, a high-capability AI model, and restored access to its Fable and Mythos frontier models following a federal export control review. The decision concludes an 18-day operational pause triggered by a US government directive on June 12, which was enacted after researchers at Amazon documented a method to bypass safety controls of Fable 5. Anthropic has since developed an updated automated classifier to patch the vulnerability, clearing the path for a full commercial rollout.
💡 Why It Matters
- · The regulatory pressures facing frontier intelligence systems underscore the need for robust safety measures, as highlighted by the vulnerability identification behavior in Fable 5.
- · The development of an automated safety classifier demonstrates Anthropic's commitment to addressing these concerns and ensuring the secure deployment of its high-capacity models.
