Side-by-side benchmark comparison across knowledge, coding, math, and reasoning.
GPT-5.2 is clearly ahead on the aggregate, 91 to 43. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
GPT-5.2's sharpest advantage is in mathematics, where it averages 97.3 against 26.4. The single biggest benchmark swing on the page is AIME 2024, 99 to 26.4.
GPT-5.2 is the reasoning model in the pair, while GPT-4.1 is not. That usually helps on harder chain-of-thought-heavy tests, but it can also mean more latency and more token spend in real use. GPT-4.1 gives you the larger context window at 1M, compared with 400K for GPT-5.2.
Pick GPT-5.2 if you want the stronger benchmark profile. GPT-4.1 only becomes the better choice if you need the larger 1M context window or you would rather avoid the extra latency and token burn of a reasoning model.
