Vast.ai reviews & product details
Visit websiteVast.ai is a peer-to-peer GPU marketplace that connects GPU owners and data centers with developers, ML engineers, researchers, and AI startups seeking low-cost GPU compute infrastructure. Often described as "Airbnb for GPUs," the platform allows providers to list available hardware while renters launch Docker-based workloads on marketplace hosts using Vast.ai's orchestration layer.
Vast.ai's core differentiator is price - the platform frequently offers the cheapest RTX 4090 and H100 pricing available publicly, often significantly below hyperscalers and managed GPU providers. Users can filter listings by GPU type, VRAM, CPU, RAM, bandwidth, storage, region, and host reliability.
