Which is better for coding?
Qwen3 1.7B. It wins 1 of the 2 coding tests both models report; LFM2-1.2B wins none, and 1 is a tie.
How do you compare the two?
We use the 19 benchmark tests both models have published scores on. The verdict counts the 10 tests in the eight capability areas, and a gap under one point (ten on rating-style scales) counts as a tie. The other 9 are listed but not counted, because several are summary scores or repeat a test. Each score is the one shown on the model's own page.
