Questions people ask
Which is better, Gemini 2.5 Pro or GPT-5.4?
GPT-5.4 wins seven of the eight areas we test: coding, agents, reasoning, images and charts, math, long documents and following instructions. Gemini 2.5 Pro wins none, but costs 36% less. They are level on facts.
Which is better for coding?
GPT-5.4. It wins 4 of the 4 coding tests both models report; Gemini 2.5 Pro wins none.
Which is cheaper?
Gemini 2.5 Pro costs $1.25 per million input tokens and $10.00 per million output tokens; GPT-5.4 costs $2.50 and $15.00. That makes Gemini 2.5 Pro about 36% cheaper for the same work.
How do you compare the two?
We use the 36 benchmark tests both models have published scores on. The verdict counts the 21 tests in the eight capability areas, and a gap under one point (ten on rating-style scales) counts as a tie. The other 15 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.
