FAQ about Vast.ai

QWhat is Vast.ai?

Vast.ai is an open marketplace where anyone can rent GPUs from independent hosts around the world. You get instant access to high-performance GPUs for AI, ML, rendering, and scientific computing—no contracts required.

QHow do I rent a GPU on Vast.ai?

Sign up, add credit, then search the live inventory. Pick your GPU, set the max price, and deploy a Docker container in one click—or automate it with the CLI/API.

QWhat pricing options are available?

On-demand (guaranteed uptime), interruptible spot (lowest cost), and reserved long-term instances. All billing is per-second, so you pay only while the instance is running.

QWhich GPU models can I use?

From consumer RTX 3060/4090 to data-center H100, A100, B200, and MI300. Availability changes in real time; use the filters to find the exact card you need.

QDo I have to sign a long-term contract?

No. There are no minimum spend or duration requirements—start and stop instances whenever you want.

QIs Vast.ai safe for sensitive data?

Hosts are rated for security and compliance, but you retain full responsibility for encryption and data handling. Choose verified Tier-3/4 datacenter hosts for extra assurance.

QWhat developer tools are provided?

Full-featured CLI, Python SDK, and REST API for searching, launching, monitoring, and terminating instances programmatically.

QHow reliable are the instances?

Reliability depends on the host. For mission-critical jobs select on-demand instances with high uptime scores and set up snapshots for quick recovery if an interruptible instance is reclaimed.
