Google coral USB and m.2 devices are TPUs.

TPU / neural compute accelerator / Math coprocessor;

From https://news.ycombinator.com/item?id=45848676 :

> How does Cerebras WSE-3 with 44GB of 'L2' on-chip SRAM compare to Google's TPUs, Tesla's TPUs, NorthPole, Groq LPU, Tenstorrent's, and AMD's NPU designs?

There are TPUs made out of silicon carbide with standard fab.

There is in-flight tensor processing with photons, but that's not quite a TPU.

Yes. Google is famously selling TPUs on prem to big customers (e.g., Anthropic) and Crux AI is now a venture to do just that.

Maybe just marketing, but they call the NPUs in their Pixel phones "TPUs"

I dont think big companies like Google react to news like that. Very likely this was meant to go out on Tuesday for weeks now. And it just happened to have coincided with another news.

They do different things and sit in different parts of the stack (training vs inference). TorchTPU seems more like a play to get more people familiar with Googles TPU chips as they want to sell them to people outside of google.

lol no this is a replacement for https://github.com/pytorch/xla

Yeah they read the news this morning and whipped up a quick Torch->XLA translation layer and coordinated with four different inference engines (who also all wrote their own blog posts) and shoved this out the door quick to stay on top of the news cycle

it doesn't seem like there's an abundance of shovels coming anytime soon

Products can also be a moat.
