Anthropic on Tuesday, August 5, introduced its most advanced model capable of software development – the Claude Opus 4.1. According to the Google-backed AI startup, the new model is an upgrade to Claude Opus 4 and is capable of agentic tasks, real-world coding, and reasoning tasks. The company revealed that it has plans to roll out larger improvements to its models in the coming weeks.
The new Opus 4.1 is currently available to paid Claude users in Claude Code. Besides, Anthropic is also offering it on its API, Amazon Bedrock, and Google Cloud’s Vertex AI. However, the Opus 4.1 is priced similar to its predecessor. Apart from real-world coding, the model excels in in-depth research, data analysis tasks, especially those that require agentic action and attention to detail.
Claude Opus 4.1 performance
When it comes to performance, the new Opus 4.1 comes with noticeable coding upgrades which boosts its score from 72.5 per cent to 74.5 per cent on SWE-bench verified. The model has also demonstrated improvements across math, agentic terminal coding (TerminalBench), GPQA reasoning, visual reasoning (MMMU) benchmarks.
According to Anthropic, users have cited real-world gains saying that the Opus 4.1 excels at tasks like multi-file code refactoring and identifying correlations in codebases.
Earlier this year, Anthropic had introduced Claude Opus 4, which the company claimed to be the world’s best coding model offering sustained performance on complex, long-running tasks and agent workflows.
Claude Opus 4.1 is also available on GitHub Copilot Enterprise and Pro+ plans. Users can also access the model in GitHub Copilot Chat on github.com, Visual Studio Code, and GitHub Mobile through the chat model picker. Meanwhile, the model in Visual Studio Code is available in ask mode. “Claude Opus 4 will remain available in the model picker, but it will be deprecated in 15 days,” GitHub said in its blog.
With its latest AI model, Anthropic seems to be intensifying its efforts to stay relevant in the competitive AI landscape. The latest upgrade comes days ahead of OpenAI’s next big release. The Sam Altman-led company is expected to announce GPT-5, and it will likely shape how AI models of big players fare in terms of coding and software development.
