Claude’s upgraded Opus 4.1 boosts software engineering accuracy to 74.5%

Anthropic has released Claude Opus 4.1, an upgraded version of its flagship AI model that achieves 74.5% accuracy on software engineering tasks. The update represents a significant improvement over the previous Claude Opus 4’s 72.5% accuracy and positions Anthropic to better compete in the increasingly crowded enterprise AI market.

What you should know: Claude Opus 4.1 delivers meaningful performance gains across several key areas that matter most to enterprise users.

• Software engineering accuracy jumped to 74.5%, up from 72.5% with Claude Opus 4 and significantly higher than the 62.3% achieved by Claude Sonnet 3.7.
• The model shows particular strength in “in-depth research and data analysis skills, especially around detail tracking and agentic search,” according to Anthropic.
• Improvements focus on “agentic tasks, real-world coding, and reasoning” capabilities that are crucial for business applications.

In plain English: Agentic tasks refer to AI systems that can act independently to complete complex, multi-step goals—like a digital assistant that can research a topic, analyze the findings, and then write a comprehensive report without constant human guidance.

Availability and access: The new model is immediately available across Anthropic’s distribution channels and major cloud platforms.

• Claude customers can access Opus 4.1 today through Claude Code, Anthropic’s API, Amazon Bedrock, and Google Cloud’s Vertex AI.
• Mac users can download the dedicated Claude app, while iPhone and iPad apps are also available for mobile access.
• Anthropic has published a detailed system card providing technical specifications and performance benchmarks.

What’s coming next: Anthropic signals that bigger announcements are on the horizon as competition intensifies in the AI model space.

• The company plans “to release substantially larger improvements to our models in the coming weeks,” suggesting more significant upgrades beyond incremental performance gains.
• This timeline coincides with expected announcements from OpenAI, which is set to make news with announcements likely coming today and later this week.
• The rapid release cadence reflects the accelerating pace of AI model development as companies race to maintain competitive advantages.

Why this matters: The software engineering accuracy improvements position Claude Opus 4.1 as a serious contender for developers and enterprises looking to integrate AI into their coding workflows, while Anthropic’s promise of “substantially larger improvements” suggests the company is preparing for the next phase of AI model competition.
