Anthropic releases Claude Fable 5, a Mythos-class model for agentic work

Claude Fable 5 is Anthropic's most capable public model, built for sustained, goal-directed operation across many steps. It sits under the new Mythos-class tier, indicating it can be trusted with meaningful autonomy on complex multi-step tasks. The model can plan, execute, observe results, and revise its approach without constant human oversight.
