Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
Gemini 3 Flash is clearly ahead on the aggregate, 62 to 30. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Gemini 3 Flash's sharpest advantage is in multimodal & grounded, where it averages 79.6 against 32.4. The single biggest benchmark swing on the page is MMMU-Pro, 80 to 27.
Gemini 3 Flash is also the more expensive model on tokens at $0.50 input / $3.00 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. Gemini 3 Flash gives you the larger context window at 1M, compared with 32K for LFM2.5-1.2B-Instruct.
Pick Gemini 3 Flash if you want the stronger benchmark profile. LFM2.5-1.2B-Instruct only becomes the better choice if you want the cheaper token bill.
