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"

Google coral USB and m.2 devices are TPUs.

> 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.
