Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
GPT-5 mini is clearly ahead on the aggregate, 69 to 38. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
GPT-5 mini's sharpest advantage is in multimodal & grounded, where it averages 83.8 against 41.7. The single biggest benchmark swing on the page is MMMU-Pro, 86 to 39.
GPT-5 mini is the reasoning model in the pair, while LFM2-24B-A2B 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. GPT-5 mini gives you the larger context window at 128K, compared with 32K for LFM2-24B-A2B.
Pick GPT-5 mini if you want the stronger benchmark profile. LFM2-24B-A2B only becomes the better choice if you would rather avoid the extra latency and token burn of a reasoning model.
