Claude Opus the listed price sits at the top of Anthropic's Opus family and is positioned as a step-change upgrade over its predecessor, Opus 4.8, with stronger coding, more capable agentic behavior, and sharper professional knowledge work. It is described as a hybrid reasoning model built for serious coding and AI agents and ships with a one-the cataloged API limit. Anthropic has made it the new default model on Claude Max and the strongest tier available on Claude Pro, signaling that the company intends Opus the listed price to be a daily-use model rather than a narrowly scoped specialist. Through the Vercel AI Gateway, it is reachable under the identifier anthropic/claude-opus-5 via the unified chat-completions endpoint, letting teams route requests to it alongside other providers with budgets, monitoring, and fallbacks handled at the gateway layer.
On independent-style evaluations Anthropic reports new state-of-the-art results for Opus the listed price on coding and knowledge-work benchmarks such as Frontier-Bench and GDPval-AA, while acknowledging it still trails Mythos the listed price on cybersecurity tasks. The launch framing also stresses efficiency: at max effort on CursorBench 3.2, Opus the listed price performs within roughly the listed price percent of Claude Fable the listed price's peak score at about half the cost per task, and at any given spend it leads on high, xhigh, and max effort settings. Anthropic summarizes the value proposition as greatly improved performance for the same cost as Opus 4.8, positioning Opus the listed price as the practical default for long-running software engineering and agent workflows that benefit from a very large context window.
