Llama 4 Maverick vs o3

Pick o3 if you want the stronger benchmark profile. Llama 4 Maverick only becomes the better choice if you want the cheaper token bill or you need the larger 1M context window.

o3 is clearly ahead on the provisional aggregate, 54 to 19. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

o3's sharpest advantage is in mathematics, where it averages 14.5 against 0.7. The single biggest benchmark swing on the page is FrontierMath v2 (Tiers 1-3), 0.690% to 18.685%.

o3 is also the more expensive model on tokens at $2.00 input / $8.00 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for Llama 4 Maverick. That is roughly Infinityx on output cost alone. o3 is the reasoning model in the pair, while Llama 4 Maverick 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. Llama 4 Maverick gives you the larger context window at 1M, compared with 200K for o3.
