GPT-5 Pro is the stronger all-rounder.o4-mini is cheaper.
Scores updated · 5 tests both models report · How we compare
Where each one wins
Tests won in each of the two areas where both have results. Each piece is one test, so a longer bar means more evidence; grey means the two scored within a point of each other.
Reasoning rests on a single test.
What it costs
Prices per million tokens, roughly 750,000 words. The bars show the cost of a million tokens read plus a million written.
o4-mini costs 96% less for the same work.
The biggest differences
The tests each model wins by the widest margin, up to three each. Scores are out of 100.

Questions people ask
Which is better, GPT-5 Pro or o4-mini?
GPT-5 Pro wins all two areas where both have results: reasoning and math. o4-mini wins none, but costs 96% less.
Which is cheaper?
GPT-5 Pro costs $15.00 per million input tokens and $120.00 per million output tokens; o4-mini costs $1.10 and $4.40. That makes o4-mini about 96% cheaper for the same work.
How do you compare the two?
We use the 5 benchmark tests both models have published scores on. The verdict counts the 3 tests in the eight capability areas, and a gap under one point (ten on rating-style scales) counts as a tie. The other 2 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.
