Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
Llama 4 Behemoth is clearly ahead on the aggregate, 40 to 33. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Llama 4 Behemoth's sharpest advantage is in multimodal & grounded, where it averages 55.1 against 32.4. The single biggest benchmark swing on the page is MMMU-Pro, 60 to 27. LFM2.5-1.2B-Thinking does hit back in instruction following, so the answer changes if that is the part of the workload you care about most.
LFM2.5-1.2B-Thinking 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.
Pick Llama 4 Behemoth if you want the stronger benchmark profile. LFM2.5-1.2B-Thinking only becomes the better choice if instruction following is the priority or you want the stronger reasoning-first profile.
