The model achieves a 74.5% score on SWE-bench Verified, outperforming Opus 4 in multi-file code refactoring, precision debugging, agentic search, and data analysis tasks.
Claude Opus 4.1 is now accessible to Claude Pro, Max, Team, and Enterprise users via Claude Code, the Anthropic API, Amazon Bedrock, and Google Cloud’s Vertex AI, with no change in pricing from Opus 4.
