Vast.ai is a GPU rental marketplace where independent hosts publish offers. The marketplace supports on-demand, interruptible, and reserved rental models; price, GPU, location, and host characteristics vary by live offer. Visitors should inspect the offer itself rather than treating Vast.ai as a fixed catalog of provider-owned machine sizes.
The marketplace lists GPU rentals from hosts, with offer-specific GPU model, machine configuration, location, reliability attributes, and rate. Rental choices include on-demand, interruptible offers that can be reclaimed, and reserved terms. Current offers are queried from the marketplace rather than represented as fixed provider SKUs.
Billing and pricing
The official pricing guide describes per-second compute charges while an instance is billable, continuous storage charges while the instance exists (including when stopped), and bandwidth billed per byte at host-set rates. Rates vary by GPU, location, supply, and host; review each offer's full cost before renting.
Regions and availability
The pricing page describes live offers across 40+ data centers. This is marketplace-wide coverage, not a promise that every GPU or offer is available in every data center or at any time.
Support
The provider publishes a rental FAQ and support information through its platform. Host hardware and service characteristics are offer-specific; support scope should be confirmed for the chosen marketplace offer.
Before you buy
Vast.ai does not set one fixed price for all GPU inventory. Marketplace rates, host reliability, regional supply, and network charges vary. Interruptible instances can be paused or stopped when outbid; storage charges can continue. No static plan or price is recorded from live marketplace offers. Host-specific prices are dynamic. Vast.ai’s terms restrict systematic retrieval of website data into another database without written permission, so HostCritiq links to current marketplace offers instead of copying live listings.
Counts describe the records published on HostCritiq, not every offer Vast.ai sells. Prices can differ by billing term, region, currency and tax. Open a plan for its full terms.
