Claude Fable 5.1 is Anthropic’s latest model for demanding reasoning and long-horizon agentic work, with stronger performance in long-running coding, multistep research, and document, spreadsheet, and slide workflows. It supports text and image inputs, text output, a 1M-token context window, and adaptive thinking that is always on with effort-based steering.
