Claude Opus 5
Claude Opus 5 is the current model in Anthropic's Opus family, for complex agentic coding and enterprise work. Anthropic recommends starting with it for most workloads. It is a step-change improvement over Claude Opus 4.8, with the largest gains in deep reasoning, agentic and long-horizon tasks, and test-time compute scaling.
