This is totally fascinating.

Frankly, it sounds to me like they're having severe yield+reliability problems with the TPUv4s that aren't getting caught by wafer-level testing, and have binned the flakiest ones for use by outsiders.

A lot of yield issues show up as spontaneous resets/crashes.

It's more likely Google preempting researcher who are on a preemptable research grant, and it is happening a lot more often because there are more paying customers.

"Preemptable money" sounds like the kind of bullshit I would use to cover up failed chips. And yes, I am a VLSI engineer.
