MAI-Code-1-Flash is the stronger all-rounder.GPT-5 is better at reasoning.
Scores updated · 9 tests both models report · How we compare
Where each one wins
Tests won in each of the three 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.
Following instructions 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.
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 or MAI-Code-1-Flash?
MAI-Code-1-Flash wins two of the three areas where both have results: coding and following instructions. GPT-5 wins reasoning.
Which is better for coding?
MAI-Code-1-Flash. It wins 2 of the 3 coding tests both models report; GPT-5 wins 1.
How do you compare the two?
We use the 9 benchmark tests both models have published scores on. The verdict counts the 6 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.
