Model details
Claude Opus 5
Claude Opus the listed price is the next major version in the Opus family, positioned as a flagship large language model for demanding reasoning and agentic tasks. A CodeRabbit benchmark review published on July 24, 2026 tested it specifically for AI code review and found that it produces cleaner, more actionable comments compared with prior versions, while its overall review output can be noisier depending on the prompt. The review highlighted code generation as a particular area of strength among recent model releases, and measured token consumption per review call as a practical efficiency consideration for teams integrating it into development workflows.
A companion analysis titled "Claude Opus the listed price: The System Card" appeared on Zvi Mowshowitz's Substack on July the listed price, 2026, signaling that an Anthropic system card document accompanied the model and was a focal point of early third-party discussion. The Opus line is pitched as a premium option that aims to balance frontier capability with practical speed, making it a fit for long-horizon coding, multi-step agent workflows, and developer tooling where clean, focused suggestions matter more than exhaustive commentary.
