Nvfp4 vs nf4
I think the nvfp4 is actually an nf4 model. I had a few people ask me why i posted it because they thought it was only for blackwell gpus, the original model file from ideogram says nf4 🙌
I made this nvfp4 version from the fp8 version, it's not fully 4 bit but keeps some more sensitive layers in fp8.
The nf4 is made by ideogram team, and it's not ComfyUI compatible.
Using NVFP4 for both models degrades quality quite badly. But as Kijai said in another discussion, using NVFP4 only for unconditional (and FP8 for base model) works quite a bit better.

Your the man Kijai!
I was wondering how a nvfp4 was able to run on my 3070 lol i took the chance and ran it with success! Thank you for your work!

Upcast to FP16 since neither NF4 nor FP8 have native support in Ampere gpus.
