GPT-5.2 is the stronger all-rounder.
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.
Coding and reasoning rest on a single test each.
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.
The biggest differences
The tests each model wins by the widest margin, up to three each. Scores are out of 100.

Where GPT-5.1 Instant pulls ahead
No clear win on a test scored out of 100.
Every test, side by side
All 5 tests both models report. The winning score is in its model's colour; marks a score checked independently.
Other results3 tests, not counted
Tests outside the eight areas. They are not counted above: several are summary scores built from other tests, or the same test under another name.

Questions people ask
Which is better, GPT-5.1 Instant or GPT-5.2?
GPT-5.2 wins all two areas where both have results: coding and reasoning. GPT-5.1 Instant wins none.
Which is better for coding?
GPT-5.2. It wins the one coding test both models report.
How do you compare the two?
We use the 5 benchmark tests both models have published scores on. The verdict counts the 2 tests in the eight capability areas, and a gap under one point (ten on rating-style scales) counts as a tie. The other 3 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.
