# SGL Grid — Overview

> Decentralized, confidential AI inference. OpenAI-compatible, pay-per-call, end-to-end encrypted.

**SGL Grid** is decentralized, confidential AI inference — think "OpenRouter, but decentralized and private." Models are served by independent, hardware-attested TEE nodes; you call them through an **OpenAI-compatible API** and pay per request.

## Why the Grid

* **OpenAI-compatible** — `/v1/chat/completions`; existing SDKs work by changing the base URL.
* **Confidential** — prompts are end-to-end encrypted and run inside a TEE; responses carry an attestation. See [Confidential inference](/cloud/grid/confidential-inference).
* **Pay-per-call** — credits or x402 USDC, no subscription. See [Pricing](/cloud/grid/pricing).
* **Decentralized** — served by staked operators, not one provider.

## How a request flows

<Steps>
  <Step title="Pick a model">Browse [models](/cloud/grid/models) served on the network.</Step>
  <Step title="Authenticate">API key, session, or per-request signature — see [Wallet & auth](/cloud/concepts/wallet-auth).</Step>
  <Step title="Send">Call the OpenAI-compatible endpoint (or use the [playground](/cloud/grid/playground)).</Step>
  <Step title="Get a verifiable, private reply">The job runs in a TEE; the response is sealed to you and tagged with the node's attestation.</Step>
</Steps>
