Claude Opus 4.1 <\/strong>is an upgraded version of the Opus 4<\/strong> model, available from today for paid users in Claude Code<\/strong>, Amazon Bedrock<\/strong> and Google Cloud Vertex AI<\/strong>. The price remains unchanged, and the performance differences are \u2014 as Anthropic <\/strong>assures \u2014 clearly noticeable.<\/p>

The new version reaches 74.5% on the SWE-bench Verified<\/strong> benchmark. This represents a significant improvement in coding capabilities and is the highest score in the history of Anthropic models, surpassing both Opus 4 <\/strong>(72.5%) and Sonnet 3.7<\/strong> (62.3%).<\/p>

In tests, Claude Opus 4.1 also demonstrated better detail tracking, efficiency in code refactoring, and the ability to think precisely using extended thinking<\/em><\/strong> \u2014 a mode that utilizes up to 64,000 tokens. In the TAU-bench<\/strong> benchmarks, the model operated in multi-stage scenarios covering up to 100 steps (averaging below 30), performing reasoning and using tools at separate stages. Claude Opus 4.1 uses two tools: bash and a text string-based file editor. Unlike Sonnet 3.7, it no longer uses a separate planning tool.<\/p>

The model operates on the same architecture but with a new range of capabilities \u2014 especially in multi-stage tasks and code refactoring. Its results are comparable to OpenAI’s model o3 and Google’s Gemini 2.5 Pro. <\/p>
