LFM2-24B-A2B vs LFM2.5-1.2B-Instruct

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

LFM2-24B-A2B 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.

LFM2-24B-A2B's sharpest advantage is in reasoning, where it averages 46.6 against 32.1. The single biggest benchmark swing on the page is HumanEval, 42 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.

LFM2-24B-A2B is also the more expensive model on tokens at $0.03 input / $0.12 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for LFM2.5-1.2B-Instruct. That is roughly Infinityx on output cost alone.

Quick Verdict

Pick LFM2-24B-A2B if you want the stronger benchmark profile. LFM2.5-1.2B-Instruct only becomes the better choice if instruction following is the priority or you want the cheaper token bill.
