What Is Vast.ai?
Vast.ai is a marketplace for renting GPU compute from independent hosts and data centres. The sources disagree widely on H100 prices, and most appear to be vendor or affiliate content, so check the live pricing before budgeting. Several 2026 sources put H100 listings around $0.90 to $2.27 an hour, with one saying unverified hosts list H100 from roughly $0.90 to $1.60 while datacentre-verified hosts run $1.50 to $2.27. On interruptible pricing, one source reports an H100 starting rate of $0.67 per GPU-hour against $1.73 for hourly listings, another lists H100 PCIe at about $1.20 interruptible against $1.85 on demand in April 2026, and a third says interruptible instances are generally 30% to 50% or more cheaper than on-demand from the same host.
There is a major outlier: Thunder Compute's October 2026 table lists Vast.ai H100 in current US listings at about $10.84 an hour on demand, far above every other source, which I could not verify. Hidden costs matter: GPUnex estimates that on unverified marketplace hosts, downtime and forced restarts raise effective costs by 20% to 40%, and interruptible jobs fit well only if they checkpoint regularly, since a higher bid or an on-demand renter can take the machine. Lambda and RunPod list H100s at roughly $2 to $4 an hour in these sources, which puts Vast.ai below them on sticker price, but you trade away consistency and host vetting.
Vast.ai suits cost-sensitive researchers and hobbyists running fault-tolerant jobs. Compare RunPod, Lambda and Paperspace. Browse the MLOps & Infrastructure tools directory for more.
