At a glance

Vast.ai is a peer-to-peer GPU marketplace connecting GPU owners and compute users. Used by ML engineers, researchers, and startups training models or running inference cheaply by renting spare GPU capacity. Salary: $120–170k (ML/data roles). Learn in 4–6 weeks. Sits alongside AWS EC2, Paperspace, and Lambda Labs (but more cost-effective).

What is Vast.ai GPU Marketplace

Vast.ai is a peer-to-peer GPU marketplace where GPU owners lease spare capacity to compute users. Instead of renting from hyperscalers (AWS, GCP, Azure) at premium prices, you rent directly from providers (miners, researchers, companies with extra GPUs) at lower rates. Cost savings are significant: 50–90% cheaper than cloud providers. You browse available GPUs, place a bid or accept fixed pricing, SSH into the instance, and run your code. Vast provides templates, Docker support, and billing. Trade-off: less support, variable availability, no guaranteed SLA.

❓ FAQ

How much cheaper is Vast.ai than AWS/GCP?

2–10x cheaper depending on GPU type. A40 GPU might be $0.30/hr on Vast vs. $0.88/hr on AWS. Trade-off: less support, instance availability varies, no SLA.

Can I be sure my instance won't disappear?

No guaranteed availability. Providers can reclaim GPUs. Some offer 'secure' pricing for guaranteed availability (slightly higher). Design for interruptions: save checkpoints, use preemptible billing.

How do I set up and run code on Vast.ai?

SSH into instance, clone repo, install dependencies, run training script. Or use Docker to deploy containers (cleaner, reproducible). Both work.

What GPU types are available?

Wide variety: RTX 3090, A40, A100, H100, V100, etc. Search by specs (memory, bandwidth, price). Popular: RTX 3090 (affordable), A100 (expensive, powerful).

Do I need to bid on instances?

Not always. Fixed-price instances are available. You can also place bids on spot instances. Bidding helps you snag cheaper capacity; fixed-price is simpler.
