Anthropic releases Claude Opus 5
Anthropic
Anthropic launched Claude Opus 5 on July 24, 2026, a faster and more cost-efficient Opus-tier model that approaches Claude Fable 5's frontier intelligence at the same $5/$25 per million token price as its predecessor Opus 4.8. It became the default model on Claude Max, the strongest available on Claude Pro, and shipped the same day as availability in GitHub Copilot for complex, long-running coding tasks.
Why it matters
Opus 5 sets a new state-of-the-art on coding and knowledge-work benchmarks like Frontier-Bench and GDPval-AA while undercutting rival flagship pricing, and its same-day rollout into GitHub Copilot shows how quickly frontier releases now propagate into third-party developer tooling.
