Seems like what Apple's going for with afm3. Their latest model that will be embedded in macOS 27 is a quantized dense 20B that only select between 1 to 4B at inference, based on the prompt, not token by token. If only they could make a 100B or 400B dense that selects ~5 to 15B...
Nothing to understand. Straight up hallucination. I could have sworn I read that they used a novel architecture where the model is dense but you could select specific layers or something at inference. reread the announcement: just said MoE. Corrected my brain's weights so thanks.
I would wager not a lot. There are some real hard constraints in space, from power consumption, to weight to thermal output (lack of convection is a real PITA for thermal shedding), and the list goes on.
