ZDNET’s key takeaways
- Anthropic launched Claude Opus 4.1.
- The mannequin exceeds the predecessor’s efficiency on advanced duties.
- It’s obtainable to paid Claude customers, Claude Code, API, Amazon Bedrock, and Google Cloud’s Vertex AI.
In Could, Anthropic launched Claude Opus 4, which the corporate dubbed its strongest mannequin but and the very best coding mannequin on the planet. Solely three months later, Anthropic is upping the ante additional by launching the extremely anticipated Claude Opus 4.1, which now takes its predecessor’s crown as Anthropic’s most superior mannequin.
The Opus household of fashions is the corporate’s most superior, clever AI fashions geared towards tackling advanced issues. Because of this, Claude Opus 4.1, launched on Tuesday, excels at these duties and might even one-up its predecessor on agentic duties, real-world coding, and reasoning, in line with Anthropic.
The mannequin additionally comes because the business is anticipating the launch of OpenAI’s GPT-5 quickly.

How does Claude Opus 4.1 carry out?
One of the spectacular use circumstances of Claude Opus 4 was its efficiency on the SWE-bench Verified, a human-filtered subset of the SWE-bench, a benchmark that evaluates LLMs’ talents to resolve real-world software program engineering duties sourced from GitHub. Claude Opus 4’s efficiency on the SWE-bench Verified supported the declare that it was the “greatest coding mannequin on the planet.” As seen within the publish above, Opus 4.1 carried out even greater.
Claude Opus 4.1 additionally swept its previous fashions throughout the benchmark board, together with the MMMLU, which exams for multilingual capabilities; AIME 2025, which exams for rigor on highschool match competitors questions; GPQA, which exams for efficiency on graduate-level reasoning prompts; and extra. When pinned in opposition to opponents’ reasoning fashions, together with OpenAI o3 and Gemini 2.5 Professional, it outperforms them in varied benchmarks, together with SWE-bench Verified.
With the discharge, Anthropic additionally posted its system card, which delineates all the security assessments and evaluations it carried out on the mannequin, in addition to its weaknesses, dangers, and limitations. A fast overview of the 22-page doc reveals that the mannequin was deployed with an AI Security Degree 3 (ASL-3) Commonplace underneath Anthropic’s Accountable Scaling Coverage (RSP), and it’s nonetheless liable to a lot of the similar vulnerabilities.
How are you going to entry Claude Opus 4.1?
If you wish to attempt the mannequin for your self, it’s now obtainable to everybody through the paid Claude plans, which embody Claude Professional for $20 per 30 days and Claude Max for $100 per 30 days. It’s obtainable in Claude Code, the API, Amazon Bedrock, and Google Cloud’s Vertex AI.
