Buy one giant GPU cluster and keep feeding it forever? Cute. The smarter play is renting exactly what you need, per second, then ghosting.
Vast AI is agent-ready infrastructure for the new reality. Provision GPUs via API, let agents optimize in the background, and watch costs behave. Real-time pricing across 20,000+ GPUs and 40+ data centers means you pick speed, price, or both. No contracts. Start with 5 dollars, grab an API key, ship.
Three ways to run: GPU Cloud for full control, Serverless for zero-ops inference, and Clusters for multi-node training with InfiniBand. Every instance is deployed through code via CLI, SDK, or API. Your workflows stay programmatic. Your ops team stops firefighting.
The platform benchmarks across 68+ GPU types so your workloads land on the best fit. Serverless endpoints autoscale to zero and only bill for compute time. Clusters give you dedicated performance for big training runs without hardware drama.
Grab a ready-to-deploy model from the library or bring your own. Launch inference, fine-tune, batch jobs, or agentic pipelines in minutes. Real-time, queryable pricing keeps procurement honest while per-second billing slashes idle burn.
Result: faster experiments, cheaper throughput, and fewer surprises. You run the business. Let the GPUs run themselves.
Best features:
- Real-time GPU pricing via API cuts procurement guesswork and cost
- Per-second billing reduces idle spend on bursty workloads
- Serverless inference autoscale to zero for hands-off performance
- Dedicated GPU clusters with InfiniBand for large-scale training speed
- Agent-ready API so AI agents can procure and optimize compute
- Model library to deploy popular models in minutes, not weeks
Spin up the right GPU in seconds, pay by the second, and ship faster without babysitting infrastructure.
Use cases:
- Scale LLM inference for chat, agents, and support with autoscaling endpoints
- Train and fine-tune custom models without buying or managing hardware
- Spin up GPU capacity for marketing campaigns, then scale back to zero
- Run ecommerce search, recommendations, and personalization workloads
- Batch video, image, and speech processing with predictable throughput
- Build RAG and embedding pipelines with elastic, API-provisioned compute
Suited for:
SaaS, ecommerce, agencies, and AI-first startups that need elastic, API-driven GPU compute without contracts, guesswork pricing, or ops overhead.
Integrations:
- PyTorch, TensorFlow, JAX, Hugging Face, Docker, Kubernetes, Ray, MLflow, LangChain
