Claude Opus 5 ranks #1 out of 215 models on the public leaderboard with an overall score of 85.88/100. It does not yet have enough sourced coverage for BenchLM's verified leaderboard. This places it among the top tier of AI models available in 2026, competing directly with the strongest models from all major AI labs.
Claude Opus 5 is a proprietary model. It uses explicit chain-of-thought reasoning, which typically improves performance on math and complex reasoning tasks at the cost of higher latency and token usage.
Available on all Claude platforms and through the Claude API as claude-opus-5. It is the default model on Claude Max and the strongest model offered on Claude Pro. Anthropic lists Opus 5 at $5 input / $25 output per million tokens, with Fast mode running around 2.5× the default speed at twice the base price.
BenchLM links it directly to Claude Opus 4.8 as the earlier related model in that lineage. This profile currently has 79 of 369 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 Knowledge (#1), while its weakest is Coding (#9). This performance profile makes it particularly effective for knowledge-intensive tasks like research, analysis, and factual Q&A.
Peer position
Exact provisional scores and ranks for the closest listed peers. A score can appear before a model clears the evidence threshold for a rank, so equal scores can have different rank states.
