The real improvement will be when the software engineers get into the training loop. Then we can have MoE that use cache-friendly expert utilisation and maybe even learned prefetching for what the next experts will be.
- zozbot234 7mo ago> maybe even learned prefetching for what the next experts will be Experts are predicted by layer and the individual layer reads are quite small, so this is not really feasible. There's just not enough information to guide a prefetch.
- snovv_crash 7mo agoManually no. It would have to be learned, and making the expert selection predictable would need to be a training metric to minimize.
- zozbot234 7mo agoMaking the expert selection more predictable also means making it less effective. There's no real free lunch.
- yorwba 7mo agoIt's feasible to put the expert routing logic in a previous layer. People have done it: https://arxiv.org/abs/2507.20984 https://arxiv.org/abs/2507.20984
