Anthropic Launches Claude Opus 4.1: A Leap Forward in AI Coding and Reasoning Capabilities

Anthropic's powerful Opus 4.1 model is here - how to access it (and why you'll want to)

It is available to paid Claude users, Claude Code, API, Amazon Bedrock, and Google Cloud's Vertex AI. In May, Anthropic released Claude Opus 4, which the company dubbed its most powerful model yet and the best coding model in the world. Only three months later, Anthropic is upping the ante further by launching the highly anticipated Claude Opus 4.1, which now takes its predecessor's crown as Anthropic's most advanced model. The Opus family of models is the company's most advanced, intelligent AI models geared toward tackling complex problems. As a result, Claude Opus 4.1, released on Tuesday, excels at those tasks and can even one-up its predecessor on agentic tasks, real-world coding, and reasoning, according to Anthropic. The model also comes as the industry is expecting the launch of OpenAI's GPT-5 soon. Also: OpenAI could launch GPT-5 any minute now - what to expect One of the most impressive use cases of Claude Opus 4 was its performance on the SWE-bench Verified, a human-filtered subset of the SWE-bench, a benchmark that evaluates LLMs' abilities to solve real-world software engineering tasks sourced from GitHub. Claude Opus 4's performance on the SWE-bench Verified supported the claim that it was the "best coding model in the world." As seen in the post above, Opus 4.1 performed even higher. Claude Opus 4.1 also swept its preceding models across the benchmark board, including the MMMLU, which tests for multilingual capabilities; AIME 2025, which tests for rigor on high school match competition questions; GPQA, which tests for performance on graduate-level reasoning prompts; and more. When pinned against competitors' reasoning models, including OpenAI o3 and Gemini 2.5 Pro, it outperforms them in various benchmarks, including SWE-bench Verified. With the release, Anthropic also posted its system card, which delineates all of the safety assessments and evaluations it conducted on the model, as well as its weaknesses, risks, and limitations. A quick overview of the 22-page document shows that the model was deployed with an AI Safety Level 3 (ASL-3) Standard under Anthropic's Responsible Scaling Policy (RSP), and it is still prone to most of the same vulnerabilities. If you want to try the model for yourself, it is now available to everyone via the paid Claude plans, which include Claude Pro for $20 per month and Claude Max for $100 per month. It is available in Claude Code, the API, Amazon Bedrock, and Google Cloud's Vertex AI.

Anthropic releases Claude Opus 4.1 amid rival ChatGPT's advancements - The Economic Times

More improvements will be rolled out in the coming weeks, the company said. The price for Opus 4.1 remains the same as that of Opus 4.Artificial intelligence (AI) company Anthropic released an upgraded version of Claude Opus 4 on Tuesday to build capabilities in real-world coding, agentic research, creative writing and reasoning. The company said it aims to bring larger improvements in the coming weeks. The development comes after rival OpenAI announced on Tuesday the release of two open-weight language models, which are designed for advanced reasoning and are optimised to run on laptops, performing similarly to OpenAI's smaller proprietary models. Opus 4.1 is currently available to paid Claude users and in Claude Code. It's also available through tools for developers like Amazon Bedrock and Google Cloud's Vertex AI. Additionally, the price for using Opus 4.1 is the same as it was for the previous version, i.e., Opus 4. Pricing for Claude Opus 4.1 starts at $15 per million input tokens and $75 per million output tokens. Claude Opus 4.1 Opus 4.1 by Anthropic advanced the state-of-the-art coding performance to 74.5% on SWE-bench Verified that tests real-world coding problems, along with in-depth research and data analysis skills. According to GitHub, Opus 4.1 has enhanced its capabilities in multi-file code refactoring. Multi-file code refactoring means improving or reorganising code that is spread across multiple files while keeping the programme's behaviour unchanged. Developer-focussed AI coding startup Windsurf reported that Opus 4.1 delivers a one-standard-deviation improvement over Opus 4 on their junior developer benchmark, showing roughly the same performance leap as the jump from Sonnet 3.7 to Sonnet 4. The broader picture Anthropic was founded in 2021 by a group of former OpenAI employees. The San Francisco-based company is generating about $5 billion in annualised revenue, Bloomberg News has reported. In May this year, Google- and Amazon-backed Anthropic introduced its next-generation AI agents, Claude Opus 4 and Claude Sonnet 4, with coding and advanced reasoning capabilities. On facing stiff competition with giants like OpenAI, Anthropic's chief product officer Mike Krieger told Bloomberg that it was focussing on its own progress rather than competitors like OpenAI. The priority, he said, is delivering value to current customers. In a separate development, Anthropic's Claude is now listed on the General Services Administration (GSA) schedule on Tuesday, making its products readily accessible to US federal government departments and agencies with pre-negotiated pricing and terms that comply with federal acquisition regulations.
