ZDNET’s key takeaways
- Anthropic launched Claude Opus 4.1.
- The mannequin exceeds the predecessor’s efficiency on advanced duties.
- It’s accessible 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 perfect coding mannequin on the earth. 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 trade is anticipating the launch of OpenAI’s GPT-5 quickly.
Additionally: OpenAI could launch GPT-5 any minute now – what to expect
How does Claude Opus 4.1 carry out?
Probably the most spectacular use instances 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 unravel 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 earth.” As seen within the put up above, Opus 4.1 carried out even increased.
Claude Opus 4.1 additionally swept its previous fashions throughout the benchmark board, together with the MMMLU, which assessments for multilingual capabilities; AIME 2025, which assessments for rigor on highschool match competitors questions; GPQA, which assessments for efficiency on graduate-level reasoning prompts; and extra. When pinned towards rivals’ reasoning fashions, together with OpenAI o3 and Gemini 2.5 Professional, it outperforms them in numerous 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 exhibits that the mannequin was deployed with an AI Security Stage 3 (ASL-3) Commonplace underneath Anthropic’s Accountable Scaling Coverage (RSP), and it’s nonetheless liable to many of the identical vulnerabilities.
How will you entry Claude Opus 4.1?
If you wish to attempt the mannequin for your self, it’s now accessible to everybody through the paid Claude plans, which embody Claude Professional for $20 monthly and Claude Max for $100 monthly. It’s accessible in Claude Code, the API, Amazon Bedrock, and Google Cloud’s Vertex AI.
