Questions people ask
Which is better, Gemma 4 26B A4B or GPT-5.2?
GPT-5.2 wins all eight areas we test: coding, agents, reasoning, facts, images and charts, math, long documents and following instructions. Gemma 4 26B A4B wins none, but costs 97% less.
Which is better for coding?
GPT-5.2. It wins 6 of the 6 coding tests both models report; Gemma 4 26B A4B wins none.
Which is cheaper?
Gemma 4 26B A4B costs $0.13 per million input tokens and $0.40 per million output tokens; GPT-5.2 costs $1.75 and $14.00. That makes Gemma 4 26B A4B about 97% cheaper for the same work.
How do you compare the two?
We use the 45 benchmark tests both models have published scores on. The verdict counts the 26 tests in the eight capability areas, and a gap under one point (ten on rating-style scales) counts as a tie. The other 19 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.
