Welcome

Parasail provides affordable, high-performance AI inference with shared Serverless, Elastic Endpoints, and Dedicated Instances.

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

Shared, on-demand, pay-per-token inference for popular open-source models. No setup required—just call the API.

Elastic Endpoints

Dedicated GPU performance with per-token billing and no GPU-hour commitment. Available for selected models; contact sales to set up your endpoint.

Dedicated Instances

Private GPU endpoints with full control over model, hardware, and scaling, billed per GPU-hour.

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
Want dedicated GPU performance with per-token billing for an eligible model	Elastic Endpoints	Private, autoscaling capacity with no idle-GPU bill; contact sales to set up your endpoint
Need a specific or private model, predictable latency, or production SLAs	Dedicated Instances	Private GPU endpoint with full control over model, hardware, and scaling

Elastic Endpoints have one starting pricing tier at 25% above the corresponding Parasail Serverless input and output token rates. Availability is limited to selected models and expands model by model. Contact sales to confirm model eligibility and set up your endpoint. After setup, use your endpoint's status page for capacity and rate limits. See Elastic Endpoints for details.

API reference

Parasail's API is fully OpenAI-compatible. Point your existing OpenAI SDK at our base URL and start making requests.

• Base URL: https://api.parasail.io/v1

• Auth: Authorization: Bearer <PARASAIL_API_KEY>

• Get an API key: https://www.saas.parasail.io/keys

See the API Reference for full details on authentication, endpoints, and parameters.

For AI coding agents

Building on Parasail on behalf of a user? Read llms.txt for a flat index of every page, then see For AI Coding Agents for per-product setup notes. In short: use the OpenAI SDK against https://api.parasail.io/v1 with the PARASAIL_API_KEY environment variable—every endpoint is OpenAI-compatible.
