Claude Opus 5: Anthropic's New SOTA Model at Half the Price

Anthropic launches Claude Opus 5, matching frontier performance at half the cost with new benchmarks in coding and knowledge work.

Anthropic released Claude Opus 5 today, a model that approaches the frontier intelligence of Claude Fable 5 at half the price. It is now the default model on Claude Max and the strongest model available on Claude Pro.

On Frontier-Bench v0.1, Opus 5 surpasses all other models and more than doubles its predecessor Opus 4.8's performance at a lower cost per task. On CursorBench 3.2 at max effort, it scores within 0.5% of Fable 5's peak while costing half as much. The model also claims a 3x lead over the next-best model on ARC-AGI 3 and roughly 1.5x the pass rate on Zapier AutomationBench at equivalent cost.

On OSWorld 2.0, a computer-use benchmark, Opus 5 outperforms every other model at any given cost level. It trails only Mythos 5 on cybersecurity evaluations. The model is priced identically to Opus 4.8 despite the substantial gains.
