This is the version we'll be testing on our rtx 6000 today! Thank you

Why not just run FP8 on vLLM with that much vRAM? It's plenty fast.

  • For high concurrency, using the blackwell's native native W4A4 MLP compute path, nvfp4 is something like a 1.2-1.5x performance increase over FP8. We're doing data enrichment (so, tasks completed successfully + tokens/second) so the performance bump shows up in the tasks/month number.

    I am just now getting the benchmarks running against 3.8 27b but I expect similar results from benching 3.6 27b at the same quant.

    • I see. Did you see any intelligence degradation between FP8 and NVFP4 for 3.6 27B? You're using vLLM, right?
