Anthropic Releases Claude Fable 5, First Mythos-Class Model to Go Public
Anthropic has announced the release of Claude Fable 5, describing it as the most powerful model the company has ever made widely available.
According to Anthropic, Fable 5 "shows exceptional performance in software engineering, knowledge work, and vision," with its lead over other models growing as tasks become longer and more complex.
Fable 5 marks the first broad release from Anthropic's Mythos class of AI models. The company had previously stated that the Mythos family was so capable at cybersecurity tasks that it was considered too dangerous to release publicly. Anthropic indicated that the release was "made possible by new safeguards that block responses in specific high-risk areas."
