What is Spot instance?
On public clouds, a spot instance is spare capacity sold at a discount that the provider can reclaim with short notice. On EverXCloud, the spot exchange is a live market where GPU hours trade at the current best offer or at your bid.
Why it matters when renting a GPU
Interruptible capacity suits checkpointed training and batch jobs, not interactive services. Always checkpoint regularly on interruptible machines.
On an exchange, the price moves with supply and demand; a limit bid lets you wait for your price instead of paying the current offer.
Worked example
If a job checkpoints every 30 minutes and runs 6 hours, an interruption costs at most 30 minutes of recomputation, about 8.3% of the run (0.5 ÷ 6).
