According to BenchLM.ai, o1 ranks #50 out of 110 models on the provisional leaderboard with an overall score of 59/100. It does not yet have enough sourced coverage for BenchLM's verified leaderboard. While not a frontier model, it offers specific advantages depending on the use case.

o1 is a proprietary model with a 200K token context window. 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.

o1 sits inside the o1 family alongside o1-preview, o1-pro. BenchLM links it directly to o1-preview as the earlier related model in that lineage. This profile currently has 3 of 152 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 Instruction Following (#7), while its weakest is Multimodal & Grounded (#56). This performance profile makes it a well-rounded choice across a range of tasks.
