o1 vs Llama 4 Behemoth

Side-by-side benchmark comparison across knowledge, coding, math, and reasoning.

o1 is clearly ahead on the aggregate, 51 to 44. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

o1's sharpest advantage is in knowledge, where it averages 83.8 against 40. The single biggest benchmark swing on the page is MMLU, 91.8 to 48.

o1 is the reasoning model in the pair, while Llama 4 Behemoth 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. o1 gives you the larger context window at 200K, compared with 32K for Llama 4 Behemoth.

Quick Verdict

Pick o1 if you want the stronger benchmark profile. Llama 4 Behemoth only becomes the better choice if you would rather avoid the extra latency and token burn of a reasoning model.
