Claude 4.1 Opus ranks #142 out of 200 models on the public leaderboard with an overall score of 45.88/100. It also ranks #71 out of 99 on the verified leaderboard. While not a frontier model, it offers specific advantages depending on the use case.

Claude 4.1 Opus is a proprietary model with a 200K token context window. It processes queries without explicit chain-of-thought reasoning, offering faster response times and lower token usage.

Claude 4.1 Opus sits inside the Claude 4.1 Opus family alongside Claude 4.1 Opus Thinking. This profile currently has 4 of 321 tracked benchmarks. BenchLM only exposes non-generated benchmark rows publicly, so missing categories stay blank until a sourced evaluation is available.

Its strongest category is Agentic (#72), while its weakest is Coding (#85). This performance profile makes it particularly useful for coding agents, browser research, and computer-use workflows.

Peer position
