CPU offloading refers to moving some model layers from VRAM to system memory, with the CPU handling the computation, thereby breaking through VRAM capacity limits.

UnverifiedThe CPU offloading strategy keeps the weights of inactive experts resident in system memory and only temporarily loads them into GPU VRAM when selected by the router, at the cost of introducing PCIe bus transfer latency.78% similarUnverifiedOn PC platforms, when VRAM is insufficient, part of the model can be offloaded to system memory, reducing speed but still allowing it to run; on Mac, when unified memory is insufficient, the model immediately reports an error and exits.75% similarUnverifiedCPU offloading (swapping VRAM to system RAM) is a core optimization strategy for running large AI models in low-VRAM environments; when GPU VRAM is insufficient, layers or tensors not currently involved in computation are temporarily offloaded to system memory.74% similarUnverifiedCompared with FP16, 4-bit quantisation can reduce model size and memory usage to about a quarter, which is the key prerequisite for ordinary CPU machines to run local large models.73% similar
