Anthropic Releases Claude Opus 4.1 with Enhanced Coding Capabilities

Anthropic has released Claude Opus 4.1, an AI model with improved coding, reasoning, and agentic tasks. The model achieves 74.5% on SWE-bench Verified, surpassing rivals like OpenAI o3 and Gemini 2.5 Pro. However, it lags behind at tasks like visual reasoning and high school math. Opus 4.1 is available to paid Claude users and through API, Amazon Bedrock, and Google Cloud's Vertex AI.

Anthropic has released Claude Opus 4.1, an AI model that demonstrates substantial improvements in coding, reasoning, and agentic tasks. The model achieves a remarkable 74.5% accuracy on the SWE-bench Verified, a benchmark for real-world software engineering tasks [1]. This performance surpasses its predecessor, Claude Opus 4, and significantly outperforms competitors like OpenAI o3 and Gemini 2.5 Pro [2].

Claude Opus 4.1 excels in in-depth research and data analysis, particularly in detail tracking and agentic search [3]. The model's performance is particularly notable in multi-file code refactoring and pinpointing exact corrections within large codebases without introducing bugs [1]. However, it lags behind at tasks like visual reasoning and high school math.

The new model is now available to paid Claude users via subscriptions to Claude Pro ($20/month) or Claude Max ($100/month) and through various cloud platforms, including Claude Code, Amazon Bedrock, and Google Cloud's Vertex AI [2]. The pricing remains the same as Opus 4.

Anthropic's commitment to responsible AI development is evident in the comprehensive safety evaluations and AI Safety Level 3 (ASL-3) Standard deployed with the model [2]. The company has also hinted at further advancements in the coming weeks, indicating a rapid pace of innovation [2].

As the AI industry continues to evolve, Claude Opus 4.1 sets new benchmarks in performance, particularly in software engineering and reasoning tasks. This release coincides with industry expectations of OpenAI's imminent GPT-5 launch, potentially setting the stage for intense competition [2].
