Anthropic馃嚭馃嚫
anthropic/claude-fable-5Claude Fable 5 is Anthropic's most capable coding-focused model, built for long-running, ambiguous, asynchronous work such as legacy migrations and gnarly production bugs that can span hours or days. It self-corrects through verification loops and is state of the art on nearly all tested coding benchmarks, with a 1M-token context window.
