    Don’t iGPUs use the RAM as VRAM directly? You’d only need to configure how much in the BIOS (eg. by default it uses 1.5GB of 8GB or smth and you can set it to 6/8GB)

      Yes for gaming, but for LLMs I’ve heard that the bandwidth limitations of using system RAM as vram hurts performance worse than running on the CPU using system memory directly, since smaller models are more memory bandwidth limited.

      I’ve never tried to run AI on an igpu with system memory though so you could try it, assuming it will let you allocate like 32GB or more like 64GB. I think you’ll also need a special runner that supports igpus.
