Does ternary weight quantization simplify deployment of mixture of experts?

This explores whether ternary weight quantization simplifies deploying Mixture-of-Experts (MoE) models — and here the collection comes up short on the literal question. None of the retrieved material addresses ternary or low-bit quantization, the technique of crushing weights down to three values to shrink memory and speed up inference. So if quantization is what you're after, this corner of the library can't yet answer you directly. What it *can* do is reframe the question: the collection treats MoE efficiency less as a compression problem and more as a routing-and-allocation problem.

The most relevant thread argues that the way to make MoE cheaper isn't necessarily smaller weights — it's a smarter division of labor. One line of work pairs MoE routing with an O(1) N-gram lookup memory and finds a U-shaped scaling law: balancing parameters between cheap memory lookup and expensive expert computation beats spending everything on experts alone, at equal parameters and FLOPs Can lookup memory and computation work together better than either alone?. That's a deployment story too — offloading what a lookup table can handle frees the experts for what actually needs computation, which is conceptually adjacent to what quantization tries to buy you.

The corpus is also rich on *where experts come from*, which shapes how you deploy them. One approach discovers new experts by moving swarms of model 'particles' through weight space with no gradient training and only 200 validation examples Can language models discover new expertise through collaborative weight search?. Another composes task-specific experts at inference time by tuning only the singular values of weight matrices — producing lightweight, composable expert vectors that mix on the fly without interference and beat LoRA with fewer parameters Can models dynamically activate expert skills at inference time?. Both sidestep the heavy machinery of training and storing many full expert copies, which is the real deployment burden quantization also targets — just from the parameter-efficiency angle rather than the bit-width angle.

There's even a routing-layer story for multi-expert systems at scale: capability discovery via versioned semantic vectors that scales sub-linearly as the pool of specialists grows Can semantic capability vectors replace manual agent routing?. That's MoE-flavored thinking lifted to the level of whole agents — a reminder that 'simplifying deployment' can mean fixing how you *select* experts, not just how you *store* them.

So the thing worth knowing you didn't know to ask: the literature in this collection treats expert models as something you make deployable by being smarter about allocation, composition, and routing — not by shrinking the bits. If you specifically need ternary quantization, that's a gap to fill; if you need MoE that's actually cheaper to run, the answers here live in singular-value tuning and hybrid memory rather than low-bit weights.
