## FAQ

### Can I compare Nemotron 3.5 Lightning 30B A3B NVFP4 and Nemotron Diffusion 8B (optimized vLLM) on BenchLM yet?

Not fully yet. BenchLM is tracking both models, but sourced benchmark coverage is still incomplete for a fair score-level comparison.

### Why does this page show "coming soon" values?

BenchLM only calls winners when public benchmark coverage is available on both sides of the comparison.
