Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
GPT-5.2 Instant is clearly ahead on the aggregate, 85 to 32. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
GPT-5.2 Instant's sharpest advantage is in coding, where it averages 75.5 against 13.2. The single biggest benchmark swing on the page is AIME 2023, 99 to 30.
GPT-5.2 Instant is the reasoning model in the pair, while Mistral 7B v0.3 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-5.2 Instant gives you the larger context window at 128K, compared with 32K for Mistral 7B v0.3.
Pick GPT-5.2 Instant if you want the stronger benchmark profile. Mistral 7B v0.3 only becomes the better choice if you would rather avoid the extra latency and token burn of a reasoning model.
