I wanna see an inference chip where the weights are part of the rom of the chip.
There would be 1 multiplier per weight (and since they're constant, the whole thing turns into a bunch of simple adders), and the total pipelined system throughput would be one token per clock cycle.
That means you can probably have millions of users simultaneously using a single bit of silicon, with perhaps 500 million tokens per second coming out the output bus.
Downside is this chip would be huuuuge - a whole wafer.
Wafer level faults probably won't matter though - neural nets are resistant to a few missing or wrong weights.
Due to the speed the industry moves, you'd want to race from model weights to production super fast, make 50 wafers, use them for a year, then bin them when that model is obsolete.
