Questions people ask
Which is better, Gemini 3.1 Pro or GPT-6.1 Sol?
GPT-6.1 Sol wins six of the eight areas we test: coding, agents, reasoning, images and charts, math and long documents. Gemini 3.1 Pro wins none. They are level on facts and following instructions.
Which is better for coding?
GPT-6.1 Sol. It wins 3 of the 4 coding tests both models report; Gemini 3.1 Pro wins 1.
Which is cheaper?
Gemini 3.1 Pro costs $2.00 per million input tokens and $12.00 per million output tokens; GPT-6.1 Sol costs $2.00 and $2.50. That makes GPT-6.1 Sol about 68% cheaper for the same work.
How do you compare the two?
We use the 32 benchmark tests both models have published scores on. The verdict counts the 24 tests in the eight capability areas, and a gap under one point (ten on rating-style scales) counts as a tie. The other 8 are listed but not counted, because several are summary scores or repeat a test. Each score is the one shown on the model's own page.
