> 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.

It's feasible to put the expert routing logic in a previous layer. People have done it: https://arxiv.org/abs/2507.20984

Manually no. It would have to be learned, and making the expert selection predictable would need to be a training metric to minimize.

Making the expert selection more predictable also means making it less effective. There's no real free lunch.
