Anyone tried this:

b12x is an SM120/SM121 CuTe DSL kernel library for (primarily) NVFP4 LLM inference.”

It didn’t work for me using mods/exp-b12x from the @eugr repo, that’s why I ended up using a Cutlass. qwen397b did work for me with mods/exp-b12x.

could you please share your launch code, thanks!

can you tell me what speed do you get for token generation, please?

b12x doesn’t support all models :(

Using FlashInter I get a lower score on the NVFP4 model

I’m sharing my experience of using Minimax 2.7 weights and comparing the two formats, AWQ and NVFP4.
Recently, I launched nvidia/MiniMax-M2.7-NVFP4 · Hugging Face, and previously, I used the weights of the cyankiwi/MiniMax-M2.7-AWQ-4bit · Hugging Face model.
My observations are as follows:

  1. The AWQ model worked quite quickly, as in the tests mentioned above by other users, but the results were very unstable. I periodically conducted tests on the same task, and what annoyed me was the lack of stability in the quality of the responses. The responses were of average quality (subjectively), but about 30% of the responses had critical errors. For this reason, I was suspicious of the MiniMax 2.7 model… and I didn’t understand why so many people praised it so much…
  2. Now about using the NVFP4 format - with many repeated tests (this is a task from my field of work, code + finance), the results became stable and the difference in the answers was not significant! This is very important to me!!! It’s better to have a slightly above-average result and almost no drops in quality - at least you can be sure that there will be no failures in practical use!

The only downside I can see is the speed of 26-28 t/s, but for me, this is the second most important thing - the main thing is stable quality!

There is an excellent thread discussing output quality and the importance of KV cache quantization and computation modes:

One thing that stands out in your config is --dtype auto. It’s possible that the actual data type differs between nvfp4 and AWQ, which could explain the discrepancy in performance.

Ideally, both models should be tested under the exact same conditions as suggested in the thread mentioned above (–dtype bfloat16 --kv-cache-dtype fp8_e4m3). It would be interesting to see if the difference persists—though, of course, it’s entirely possible.

I am not certain which higher precision data types work best with NVFP4 - would be worth testing to be certain. bfloat16 works well with INT4 AutoRound.
