Welcome
Parasail is a cloud GPU platform for AI inference. We aggregate top AI hardware providers to give you scalable, on-demand access to powerful computing resources—without costly hardware investments or lengthy contracts.
We offer three ways to run inference, each designed for a different workload pattern:
| Type | Description | Link |
|---|---|---|
| Serverless | On-demand, pay-per-token inference for popular open-source models. No setup required—just call the API. | Link |
| Dedicated Instances | Private GPU endpoints with full control over model, hardware, and scaling. Ideal for production workloads. | Link |
| Batch Processing | Process millions of inferences at 50% off serverless pricing. OpenAI-compatible batch API. | Link |
Not sure where to start?
Pick a product based on your workload:
| If you... | Use | Why |
|---|---|---|
| Want to call a popular open-source model with no setup | Serverless | Pay-per-token, instant, OpenAI-compatible |
| Need a specific or private model, predictable latency, or production SLAs | Dedicated Instances | Private GPU endpoint with full control over model, hardware, and scaling |
| Process large volumes offline where real-time isn't required | Batch | 50% off serverless pricing, up to millions of requests |
Find your path
Choose the option that best matches what you're trying to do:
