Anthropic Ships Claude Opus 5, Its Fourth Model in Two Months, at Unchanged Pricing

Anthropic released Claude Opus 5 on July 24, describing it as a major improvement for the Opus tier aimed at long-running agents, coding, and professional work. The company kept pricing at $5 per million input tokens and $25 per million output tokens, matching the prior Opus generation.

On agentic and reasoning evaluations, Anthropic reports Opus 5 scoring about 30 percent on ARC-AGI-3, compared with 7.8 percent for GPT-5.6 Sol and 1.5 percent for Opus 4.8, and roughly 71 percent on OSWorld 2.0 for computer use. On Frontier-Bench, an agentic terminal-coding evaluation that measures whether a model can build working software from specifications, Anthropic says Opus 5 more than doubles its predecessor's score and passes every competitor tested, including the company's own Fable 5 tier, at a lower token price.

These figures are largely vendor-reported, and ARC-AGI-3 is a new evaluation without an established independent baseline, so the multiples deserve caution until third parties reproduce them. The release pace is itself informative. Four models in two months places coding and agentic autonomy at the center of Anthropic's plans, and holding the price steady suggests the competition is now on capability per dollar rather than on top benchmark scores alone.
