Claude Opus 5 is Anthropic's flagship model, released on July 24, 2026 as the successor to Opus 4.8 at the top of the Claude lineup. It carries a 1 million token context window, up to 128K output tokens, and adaptive thinking that scales reasoning depth to the difficulty of each request. At launch it posted Anthropic's strongest results to date on coding and knowledge work evaluations. The model is built for complex agentic coding and demanding enterprise work, staying coherent through long multi-step sessions where large codebases and document sets must remain in view. With vision, PDF understanding, tool use, and structured output, it suits deep refactoring projects, research-grade analysis, and agents that plan and execute over extended horizons.
