Anthropic introduced Claude Opus 5, a thoughtful, proactive model with near-frontier performance at about half the cost of Claude Fable 5. It sets the state of the art on coding benchmarks, doubles Opus 4.8's Frontier-Bench score, beats everything but Fable 5 on OSWorld 2.0 at a third of the cost, and produces the strongest visual output of any Opus yet. Pricing stays at $5/$25 per million tokens. It's the new default on Claude Max, the strongest model on Pro, and available in the API, Claude Code, and Claude Cowork, with Fast mode support.
