Claude Opus 4.1

by Anthropic

Claude Opus 4.1 builds on Opus 4 with notable improvements in agentic tasks, real-world coding, and research. It scores 74.5% on SWE-bench Verified, advancing state-of-the-art coding performance, with particularly strong gains in multi-file code refactoring. The upgrade sharpens in-depth research and data analysis, especially detail tracking and agentic search, making it more effective for complex investigative workflows and multi-step reasoning. On a third-party junior developer benchmark, Windsurf measured a leap from Opus 4 comparable to the jump from Sonnet 3.7 to Sonnet 4. With a 200K token context window and support for vision, tools, and structured output, Opus 4.1 strengthens professional coding, research, and knowledge work.
