)One Platform, Three Ways to Deploy
GPU Cloud for full control. Serverless for zero-ops inference. Clusters for large-scale training.
GPU Cloud
On-demand instances across 40+ data centers and 20,000+ GPUs. Deploy in seconds, scale without limits.
Serverless
Deploy models as endpoints. Autoscale to zero, pay only for compute time — no idle costs.
Clusters
Dedicated multi-node GPU clusters with InfiniBand networking for large-scale training.
Built for Every AI Workload
From training to inference, fine-tuning to rendering — run any GPU workload on Vast.
