GLM-4.7-Flash vs LFM2.5-1.2B-Instruct

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

GLM-4.7-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.

GLM-4.7-Flash's sharpest advantage is in coding, where it averages 45.9 against 7.2. The single biggest benchmark swing on the page is HumanEval, 58 to 14.

GLM-4.7-Flash is the reasoning model in the pair, while LFM2.5-1.2B-Instruct 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. GLM-4.7-Flash gives you the larger context window at 200K, compared with 32K for LFM2.5-1.2B-Instruct.

Quick Verdict

Pick GLM-4.7-Flash if you want the stronger benchmark profile. LFM2.5-1.2B-Instruct only becomes the better choice if you would rather avoid the extra latency and token burn of a reasoning model.
