Pick LFM2.5-8B-A1B if you want the stronger benchmark profile. DeepSeek V3 only becomes the better choice if instruction following is the priority or you would rather avoid the extra latency and token burn of a reasoning model.
LFM2.5-8B-A1B is clearly ahead on the provisional aggregate, 50 to 35. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
DeepSeek V3 is also the more expensive model on tokens at $0.27 input / $1.10 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for LFM2.5-8B-A1B. That is roughly Infinityx on output cost alone. LFM2.5-8B-A1B is the reasoning model in the pair, while DeepSeek V3 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.
LFM2.5-8B-A1B is ahead on BenchLM's provisional leaderboard, 50 to 35. The biggest single separator in this matchup is IFEval, where the scores are 86.1% and 91.8%.
DeepSeek V3 has the edge for instruction following in this comparison, averaging 86.1 versus 79.5. Inside this category, IFEval is the benchmark that creates the most daylight between them.
