Claude Fable 5.1
Claude Fable 5.1 is a Mythos-class model from Anthropic, built for autonomous knowledge work and coding. It improves on Claude Fable 5 across the board, with the biggest gains in agentic coding, long-running agentic workflows, long code refactors, front-end and visual code generation, and finance and analysis tasks. It also tends to be more concise than Fable 5 in its plans and summaries.
It supports text, image, and file inputs with reasoning support and a 1M-token context window, making it suited for long-running, complex, and asynchronous tasks that previously required frequent human check-ins. It executes well-scoped tasks with few mistakes, automatically self-correcting through verification loops, and ships with robust safeguards.
