## FAQ

### Can I compare Hy-MT1.5-1.8B-1.25bit and Nemotron Diffusion 8B (pst2154, 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.
