That probably includes the 51b ngrams too. It's possible that those could be streamed from NVMe on-demand. The Engram paper that developed this technique streamed from RAM to VRAM at only ~1% performance degradation, but these strix halo boxes and the spark have much slower memory, so it's possible moving down another rung on the memory hierarchy wouldn't affect their performance too much.

This will almost certainly require changes to llama.cpp or vllm to do it right.
