There is no liquid 'GPU spot market': cloud preemptible pricing differs wildly across AWS, GCP, Azure, Nebius

Björn (Stability AI co-founder) pushes back on the term 'GPU spot market': there's no liquid marketplace. AWS slowly reprices spot with demand, GCP uses monthly prices, Azure offers a fixed discount, neoclouds like Nebius run auctions, and some vendors (e.g. SpaceX) sell short-term non-preemptible capacity at premium prices. Preemptibility confusion abounds.
