Anthropic launched Claude Opus 4.1, an AI model, today for customers via API integrations, enhancing software engineering accuracy and agentic capabilities.
Anthropic, an AI company, introduced its Claude 4 model family in May, emphasizing improved coding, reasoning, and instruction following. Three months later, the company has released Claude Opus 4.1. This iteration reportedly upgrades “agentic tasks, real-world coding, and reasoning.”
Anthropic states that Claude Opus 4.1 improves software engineering accuracy to 74.5%. This represents an increase from 62.3% with Claude Sonnet 3.7 and 72.5% with Claude Opus 4. The company notes the updated model excels in “in-depth research and data analysis skills, especially around detail tracking and agentic search.”
A benchmark table from Anthropic’s blog post detailing Opus 4.1 provides comparative data:
- Software Engineering Accuracy (Opus 4.1): 74.5%

- Software Engineering Accuracy (Sonnet 3.7): 62.3%
Anthropic’s latest model is available today for Claude customers. It can be accessed through Claude Code, Anthropic’s API, Amazon Bedrock, and Google Cloud’s Vertex AI platform. Additional information on Anthropic’s new model is available in the Claude Opus 4.1 system card. Anthropic indicated on social media that it plans “to release substantially larger improvements to our models in the coming weeks.” OpenAI is also expected to make announcements today and later this week. Mac users can download Claude for macOS, and Anthropic also offers iPhone and iPad applications for its Claude AI platform.
