Earlier quoted context omitted.
ASICs only work for very small and heavily quantized models. Moreover, they are fixed function hardware, so whenever you have a new model, you have to throw the current chips away and design and buy new ones. That's like buying a new CPU every time a new OS version comes out.
The latest strategies of etching weights into silicon seem like they can be generalized. We currently design gpu/tpu caching on the basis that the weights change frequently - if the weights do not change at all, or change very slowly - then there are other perhaps more efficient ways of laying out the memory on the chip which are somewhere between permanently etch a model onto silicon and use GPUs designed for graphi…
I'm assuming that they will do a silicon etching run once a year. Might be an interesting acquisition opportunity for Apple since that's the rhythm of their device release.
