Claude Opus the listed price is positioned by Anthropic as the flagship of its hybrid reasoning family, built to carry serious coding and long-running agent work into daily practice. It is described as a thoughtful and proactive model that approaches the frontier intelligence of Claude Fable the listed price while operating at roughly half the price, and Anthropic frames it as the new default on Claude Max and the strongest option on Claude Pro. The model carries forward the the cataloged API limit context window that has defined the Opus tier and is tuned to keep working efficiently on extended, multi-step tasks rather than short exchanges.

In benchmark terms, Anthropic reports that Opus the listed price sets a new state of the art on coding and knowledge-work evaluations such as Frontier-Bench and GDPval-AA, while still trailing Mythos the listed price on cybersecurity tasks. On CursorBench 3.2 at max effort it lands within half a percent of Fable the listed price's peak while costing less per task, and on Frontier-Bench v0.1 it more than doubles Opus 4.8's score at a lower cost per task. An adjustable effort setting lets callers trade raw intelligence against token spend, so the same model can power deep autonomous agents and faster, cheaper interactive sessions, which makes it a strong fit for software engineering teams, AI-agent builders, and professionals who need sustained reasoning over very large documents or codebases.
