I think there are drastic differences between computer vision models and LLMs that you’re not considering. LLMs are huge relative to vision models, and require gobs of fast memory. For this reason a little USB dongle isn’t going to cut it.

Put another way, there already exist add-in boards like this, and they’re called GPUs.

GPUs are still software programmable.

An "LLM chip" does not need that and so can be much more efficient.

Sure, but that’s somewhat orthogonal to the point I was making, which is that LLMs are huge in size. Even in the case of a custom “LLM chip,” you’ll need huge amounts of very fast storage of some sort (likely DRAM), which places constraints on the size, power consumption, and cost of such a device. This device, if it existed, would not in any way resemble the Coral TPU product that the GP was referencing; I think in fact it would be closer in size, price, and form factor to a GPU.
