Benchmark data for Gemini 1.5 Pro and GPT-5.5 is coming soon on BenchLM.
BenchLM has partial data for these models, but not enough overlapping benchmark coverage to produce a fair score-level comparison yet.
GPT-5.5 is priced at $5.00 input / $30.00 output per 1M tokens, versus $1.25 input / $5.00 output per 1M tokens for Gemini 1.5 Pro. Gemini 1.5 Pro has the larger context window at 2M, compared with 1M for GPT-5.5.
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 1.5 Pro: $1.25 input / $5.00 output per 1M tokens GPT-5.5: $5.00 input / $30.00 output per 1M tokens Both model pages still include creator, context window, reasoning mode, and other metadata while benchmark coverage fills in.
