AI firm Anthropic has released Claude Opus 4.1, an upgrade to Claude Opus 4, with improved coding, agentic tasks, and reasoning capabilities. “Opus 4.1 is now available to paid Claude users and in Claude Code. It’s also on our API, Amazon Bedrock, and Google Cloud’s Vertex AI. Pricing is the same as Opus 4,” said Anthropic in a blog post. Anthropic claims the new AI model “improves Claude’s in-depth research and data analysis skills, especially around detail tracking and agentic search.” According to the company, Opus 4.1 achieves state-of-the-art coding performance with a 74.5% score on SWE-bench Verified — a benchmark for evaluating AI models on real-world software tasks sourced from GitHub. The new model outperforms rivals including OpenAI’s o3 and Google’s Gemini 2.5 Pro in benchmarks related to agentic coding and multilingual Q&A. However, competitors surpassed Opus 4.1 in visual reasoning, high school math, and graduate-level reasoning. Last week, WIRED reported that Anthropic revoked OpenAI’s access to its Claude family of AI models, alleging a violation of its terms of service. According to the report, Anthropic claimed that OpenAI’s technical staff had been using its coding tools in the lead-up to the GPT-5 launch
