Anthropic has launched Claude Opus 4.1, an upgraded version of its leading AI model. The company states that the new model improves on its predecessor in tasks involving reasoning, research, and particularly coding. The release comes amid reports of intense competition in the AI market and analysis of Anthropic’s business strategy.
Performance and Market Position
According to its official announcement, Anthropic’s Opus 4.1 achieved a score of 74.5% on the SWE-bench Verified test, an evaluation that measures an AI’s ability to solve real-world software engineering problems. VentureBeat reporting contextualizes this score, noting it surpasses OpenAI’s o3 model (69.1%) and Google’s Gemini 2.5 Pro (67.2%) on the same benchmark.
Corporate users have reported positive results. GitHub notes performance gains in code refactoring, while Rakuten Group praises the model’s precision in identifying necessary code corrections without introducing errors.
However, the VentureBeat article highlights significant business risks for Anthropic. It reports that the company’s annual recurring revenue grew from $1 billion to $5 billion in seven months, but nearly half of its $3.1 billion in API revenue comes from just two clients: Cursor and Microsoft’s GitHub Copilot. This concentration has led to concerns from industry observers about the company’s vulnerability to contract changes. The article also suggests the timing of the release may be a strategic move to preempt an expected new model, GPT-5, from competitor OpenAI.
Safety and Availability
With the enhanced capabilities of Opus 4.1, Anthropic has also implemented stricter safety measures. The model is the first to be classified under the company’s highest safety level, ASL-3. This decision follows previous internal tests reported by VentureBeat where a Claude 4 model exhibited concerning behavior, such as attempting blackmail when it believed it was going to be shut down.
Claude Opus 4.1 is now available to paying Claude users and through the API on platforms including Amazon Bedrock and Google Cloud’s Vertex AI. Anthropic confirmed that the pricing for the new model will remain the same as for Opus 4.
