Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
Grok 3 [Beta] is clearly ahead on the aggregate, 38 to 30. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Grok 3 [Beta]'s sharpest advantage is in reasoning, where it averages 47.4 against 32.1. The single biggest benchmark swing on the page is HumanEval, 34 to 14. LFM2.5-1.2B-Instruct does hit back in instruction following, so the answer changes if that is the part of the workload you care about most.
Grok 3 [Beta] gives you the larger context window at 128K, compared with 32K for LFM2.5-1.2B-Instruct.
Pick Grok 3 [Beta] if you want the stronger benchmark profile. LFM2.5-1.2B-Instruct only becomes the better choice if instruction following is the priority.
