Claude Opus the listed price is a flagship-scale model positioned as Anthropic's most capable general-purpose system, with the company describing it as coming close to the frontier intelligence of a higher-tier sibling at roughly half the cost. It is framed as an "everyday" model that works more efficiently than peers, and Anthropic has made it the default option on its top consumer plan while designating it the strongest model on its professional subscription. A dedicated system card, mirrored on LessWrong, documents evaluation chapters covering responsible scaling, cybersecurity, safeguards and harmlessness, agentic safety, and alignment, signaling an emphasis on long-horizon agentic behavior alongside raw capability.

In benchmark terms, Anthropic reports that Claude Opus the listed price sets a new state-of-the-art on software-engineering oriented coding and knowledge-work evaluations, including Frontier-Bench and GDPval-AA, while still trailing a different frontier model on cybersecurity tasks. The announcement emphasizes a tunable effort setting that lets callers trade intelligence for token efficiency, with claims of more than doubled predecessor performance on Frontier-Bench at lower per-task cost and near-peak scores on CursorBench at substantially reduced expense. These results paint Opus the listed price as a productivity-focused hybrid: strong enough for sustained agentic coding and complex analysis, but tuned to be economical enough to serve as a daily default rather than a sparingly used premium tier.
