Benchmark data for Gemini 2.5 Pro and GPT-5.1 is coming soon on BenchLM.
BenchLM does not have sourced benchmark coverage for GPT-5.1 yet. This comparison is currently limited to metadata such as context window, reasoning mode, and pricing where available.
GPT-5.1 is priced at $1.50 input / $6.00 output per 1M tokens, versus $1.25 input / $5.00 output per 1M tokens for Gemini 2.5 Pro. Gemini 2.5 Pro has the larger context window at 1M, compared with 200K for GPT-5.1.
Not fully yet. BenchLM is tracking both models, but the sourced benchmark breakdown for this comparison is still coming soon.
BenchLM only shows category winners and benchmark-level calls when we have sourced results that can be compared fairly. For these models, the public benchmark coverage is not complete enough yet.
Gemini 2.5 Pro: $1.25 input / $5.00 output per 1M tokens GPT-5.1: $1.50 input / $6.00 output per 1M tokens Both model pages still include creator, context window, reasoning mode, and other metadata while benchmark coverage fills in.
