As someone who just fired off both paperspace boxes and coreweave to play around with stable diffusion, Paperspace limited me to some old janky hardware and never replied to my request to "unlock" the more modern cards.

Coreweave let me get a modern card box first go round. I'd go with coreweave if you are a weekend hacker who just wants access to a lil bit of beefy GPU.

YMMV.
