Parasail: Cloud GPU Platform for AI Inference
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:
Serverless
On-demand, pay-per-token inference for popular open-source models. No setup required—just call the API.
Dedicated Instances
Private GPU endpoints with full control over model, hardware, and scaling. Ideal for production workloads.
Batch Processing
Process millions of inferences at 50% off serverless pricing. OpenAI-compatible batch API.
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:
- Chat and text generation: Build chatbots, assistants, and text generation pipelines
- RAG and embeddings: Build retrieval-augmented generation and vector search systems
- Batch at scale: Process large volumes of prompts, images, or text offline
- Agents and tool calling: Build agentic workflows with function calling and multi-step reasoning
Quickstart
Make your first API call in under two minutes:
- Serverless quickstart: Call a serverless model with the OpenAI SDK
- Dedicated quickstart: Deploy your own model on a dedicated GPU
- Batch quickstart: Submit a batch job in five lines of Python
