Capabilities
About this model
Claude Fable 5.1 extends Claude Fable 5 for demanding reasoning and long-horizon agentic work. It supports text, image, and file inputs with text output, with adaptive thinking always on and a 1M-token context window. It is stronger at long-running agentic coding, multistep research, and document, spreadsheet, and slide work. Use it when evals on Claude Opus 5 at higher effort still fall short. It executes well-scoped tasks with few mistakes, automatically self-correcting through verification loops, and ships with robust safeguards.
