Pick Qwen2.5-1M if you want the stronger benchmark profile. LFM2.5-350M only becomes the better choice if its workflow or ecosystem matters more than the raw scoreboard.
Qwen2.5-1M is clearly ahead on the aggregate, 62 to 39. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Qwen2.5-1M's sharpest advantage is in knowledge, where it averages 62.1 against 23.8. The single biggest benchmark swing on the page is MMLU-Pro, 20.0% to 74%.
Qwen2.5-1M gives you the larger context window at 1M, compared with 32K for LFM2.5-350M.
BenchLM keeps the benchmark table and the operator tradeoffs on the same page so a better score does not hide a materially slower, pricier, or smaller-context model.
Runtime metrics show N/A when BenchLM does not have a sourced snapshot for that exact model. The scoring rules and freshness policy are documented on the methodology page.
