General information
Vast.ai is a GPU marketplace built for teams and systems that need fast, flexible access to compute without committing to rigid cloud contracts. It connects you to a large pool of GPUs across multiple data centers, offering everything from consumer-grade cards to high-end hardware used for large-scale AI training and inference.
The platform is designed around direct programmatic control. Through an API, CLI, or Python SDK, you can search available GPUs, compare live pricing, launch instances, and shut them down when no longer needed. This makes it especially useful for automated workflows and AI agents that can independently manage their own infrastructure decisions.
Pricing is driven by real-time supply and demand, which often results in lower costs compared to traditional hyperscalers. Billing is handled per second, so compute is only paid for while it is actively used, with no requirement for long-term reservations or minimum usage commitments.
Vast supports multiple deployment modes, including standard GPU instances for general workloads, serverless endpoints for scalable inference, and clustered setups for distributed training. A library of pre-configured machine learning environments also reduces setup time for common frameworks and models.
The platform is used for a wide range of workloads including model training, fine-tuning, inference, rendering, and data processing. Its flexibility makes it suitable for both experimental projects and production systems that require scalable compute.

Vast.ai features
AI-ready GPU marketplace for scalable, on-demand compute infrastructure
-
API-first infrastructure access
Vast.ai provides full programmatic control through API, CLI, and SDK access, allowing you or autonomous systems to search GPUs, deploy instances, manage workloads, and terminate resources without relying on manual dashboard interactions or administrative overhead.
-
Global GPU marketplace
The platform aggregates thousands of GPUs across distributed data centers worldwide, offering a wide range of hardware options from budget-friendly cards to high-performance GPUs suited for training large language learning models.
-
Per-second billing model
Compute usage is billed by the second, ensuring you only pay for active runtime. This eliminates wasted costs from idle provisioning and avoids the constraints of hourly or long-term reservation-based pricing models.
-
Real-time dynamic pricing
GPU prices adjust based on live supply and demand conditions, giving you visibility into current market rates and enabling cost-aware selection of compute resources depending on workload urgency and budget constraints.
-
Serverless model deployment
Serverless endpoints allow models to scale automatically based on demand, including scaling down to zero when idle. This makes it suitable for inference workloads with unpredictable or spiky traffic patterns.
-
Multi-node cluster support
The platform supports clustered GPU configurations connected with high-speed networking, enabling distributed training for large models that require synchronized computation across multiple machines.
-
Pre-configured ML environments
Ready-to-use templates for popular machine learning frameworks and models reduce setup time significantly, allowing you to deploy training or inference environments with minimal configuration effort.
-
Broad workload compatibility
Vast supports training, fine-tuning, inference, rendering, batch processing, and agent execution workflows, making it suitable for both research experimentation and production-grade AI systems.
