NVFP4, DFlash working on vLLM!

#30

Hey everyone. I tried this 'PR of a PR' of vLLM from xianbaoqian on GitHub on an RTX Pro 6000, and it was able to run the new Glimmer model with DFlash enabled and also supported various quants of the base model such as FP8 and NVFP4. I was able to achieve 140 tps decode with NVFP4 and DFlash enabled compared to the 120 ish I was seeing with UD Q4 K XL and DFlash on llama.cpp.

When trying FP8 I quantized on the fly. The NVFP4 quant I tried was the one I produced at https://huggingface.co/cloudnathan5/Muse-Glimmer-30B-NVFP4. That HF Repo also has commands you can reference to run it yourself.

Hope this helps anyone trying to run the model on vLLM or who is looking for an NVFP4 quantization.

Thank you Meta and all open-source contributors who made this possible!
