Claude Fable 5.1
Anthropic🇺🇸
anthropic/claude-fable-5.1Claude Fable 5.1 is Anthropic's most capable model, released September 2026 as an upgrade to Claude Fable 5 for coding, knowledge work, and long-running problem-solving, with a 1M-token context window. It improves agentic coding by over 30% and doubles its predecessor's Terminal-Bench-Science score while cutting costs through cheaper cache reads, and is the openly available counterpart to the more tightly safeguarded Mythos 5.1.
