Anthropic launches new Claude Fable and Mythos 5.2 models

Anthropic launched Claude Fable 5.2 and Claude Mythos 5.2 AI models ahead of its IPO, touting faster performance, improved coding, reasoning, and vision, lower pricing, and a new fast mode, positioning them for demanding technical work. The new models generate outputs up to 30% faster than the 5.1 versions, use fewer tokens on complex tasks, and are available on major cloud platforms. The release follows a METR report on recursive self‑improvement and aims to strengthen Anthropic’s competitive edge before listing.
