Anthropic Releases Claude Opus 4.1 with Major Upgrades in Coding and Reasoning
Anthropic has unveiled Claude Opus 4.1, the latest iteration of its leading AI model for software development. This new version builds on the foundation of Claude Opus 4, offering improved capabilities in real-world coding and reasoning. Notably, Anthropic, a Google-backed startup, emphasized that this update enables the model to handle agentic tasks with greater precision.
Currently, Claude Opus 4.1 is accessible to paid Claude users through Claude Code. It is also integrated with platforms like Amazon Bedrock, Google Cloud’s Vertex AI, and Anthropic’s API. Despite the advancements, pricing remains consistent with the previous model. In addition to programming, the model proves effective in data analysis and research especially when tasks demand attention to detail and autonomous execution.
The company stated that broader improvements across its model family are expected in the coming weeks. This signals a continued push for innovation in a rapidly evolving AI landscape.
Performance Gains Across Coding and Reasoning
Claude Opus 4.1 has shown measurable progress in key benchmarks. For instance, its SWE-bench verified score has climbed from 72.5% to 74.5%. This increase reflects upgrades in its coding capabilities. Furthermore, performance boosts were seen in math reasoning, agentic terminal coding (TerminalBench), GPQA reasoning, and multimodal tasks (MMMU).
According to Anthropic, users report real-world benefits such as easier multi-file code refactoring and improved ability to detect correlations across large codebases. These enhancements are particularly useful in complex development environments, where efficiency and accuracy matter.
Earlier this year, the company launched Claude Opus 4, which it described as the world’s best coding model. That version was praised for its stability on long-running tasks and agent workflows, setting a strong foundation for this latest release.
Availability and Market Context
Claude Opus 4.1 can now be accessed via GitHub Copilot Enterprise and Pro+ plans. Users can use the model in GitHub Copilot Chat on GitHub.com, Visual Studio Code, and GitHub Mobile. In Visual Studio Code, it is currently available in ask mode. GitHub stated, “Claude Opus 4 will remain available in the model picker, but it will be deprecated in 15 days.”
This release positions Anthropic to compete more directly with rivals ahead of OpenAI’s anticipated launch of GPT-5. With both companies advancing quickly, the AI space is set for significant changes particularly in how models contribute to coding and development workflows.
