Side-by-side benchmark comparison across knowledge, coding, math, and reasoning.
o3-mini is clearly ahead on the aggregate, 56 to 51. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
o3-mini's sharpest advantage is in knowledge, where it averages 82.1 against 45.3. The single biggest benchmark swing on the page is MMLU, 86.9 to 53.
o3-mini is the reasoning model in the pair, while Moonshot v1 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. o3-mini gives you the larger context window at 200K, compared with 128K for Moonshot v1.
Pick o3-mini if you want the stronger benchmark profile. Moonshot v1 only becomes the better choice if you would rather avoid the extra latency and token burn of a reasoning model.
