Benchmark data for Gemini 3 Pro and GPT-4 Turbo is coming soon on BenchLM.
Confidence note. This is a partial-evidence comparison with 3 shared benchmark results across 2 evidence categories; 0 of 8 categories currently have scoreable aggregates for both models. Treat the verdict as directional until coverage is more balanced.
Why this result
BenchLM has partial data for these models, but not enough overlapping benchmark coverage to produce a fair score-level comparison yet.
GPT-4 Turbo is priced at $10.00 input / $30.00 output per 1M tokens, versus $2.00 input / $12.00 output per 1M tokens for Gemini 3 Pro. Gemini 3 Pro has the larger context window at 2M, compared with 128K for GPT-4 Turbo.
