Questions people ask
Which is better, Gemini 2.0 Flash (Non-Reasoning) or GPT-5?
GPT-5 wins all six areas where both have results: coding, agents, reasoning, facts, long documents and following instructions. Gemini 2.0 Flash (Non-Reasoning) wins none.
Which is better for coding?
GPT-5. It wins 2 of the 2 coding tests both models report; Gemini 2.0 Flash (Non-Reasoning) wins none.
How do you compare the two?
We use the 24 benchmark tests both models have published scores on. The verdict counts the 11 tests in the eight capability areas, and a gap under one point (ten on rating-style scales) counts as a tie. The other 13 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.
