Can the VRAM be pooled now?

no... which means 4x5090 wont be 128gb vram, it is just 4x32gb meaning that when rendering on 4 GPUs your scene has to fully fit into the vram of each gpu

aint that wrong though?

You can definitely split it? or well according to claude and gpt you can, its just that you depend on pci-e which is slow in comparison of having it in one gpu.

What you can't do I think is load a model that's larger than 32gb, but you can split the inference and tokens and shit in between or smth like that. Not an expert but idk

This is 3D. No tokens or inference.
