Claude Fable 5

Claude Fable 5 is a Mythos-class model from Anthropic, built for autonomous knowledge work and coding. It supports reasoning and long-running, complex, asynchronous tasks that previously required frequent human check-ins, with a 1M-token context window and text, image, and file inputs.
