NVFP4 support on day 0?
plsss
They are BIG, I mean REALLY BIG (130GB+)
They are BIG, I mean REALLY BIG (130GB+)
That’s because most of the model is the BF16 lookup table, which some people have found can be run from your SSD without performance loss. But idk what inference providers even support that for NVFP4 as of now.

Some have claimed this is not possible with the unsloth quants.

I already did it with the Unsloth quant, if you set load mode to mmap it should just work. Might have to increase the memory page swap size as well in your OS if it errors for some reason
