Claude Opus 5 halves cost, matches flagship Fable 5 performance
Anthropic launched Claude Opus 5, a model that matches the intelligence of its flagship Fable 5 at roughly half the price. Benchmarks show Opus 5 setting new state‑of‑the‑art scores on coding, knowledge work, and scientific tasks while using far fewer tokens, making it the default on Claude Max and the strongest option on Claude Pro.
