Claude Fable 5
Claude Fable 5 is Anthropic's Mythos-class model, designed for autonomous knowledge work and coding. It accepts text, image, and file inputs, produces text output, and features reasoning capabilities along with a 1M-token context window. The model excels at long-running, complex, and asynchronous tasks that once demanded frequent human oversight. Its core strength lies in handling end-to-end work that would typically take a person hours, days, or even weeks — tackling problems that are extended, ambiguous, or involve many interdependent steps. It carries out well-defined tasks with minimal errors, self-corrects through built-in verification loops, and comes with robust safeguards.
