# Playground (Chat)

> Try any model served on the Grid directly in your browser — confidential, pay-per-message.

The **Playground** is a browser chat for trying models served on SGL Grid. It's the fastest way to see the network work end to end — and it runs the same confidential path as the API.

## What you can do

* **Chat with any live model** — pick from the served models.
* **Pay your way** — use prepaid **credits** or pay **per message** with USDC (x402). Choose your chain for x402.
* **See the proof** — each reply shows a **TEE attestation badge** (e.g. "Verified TEE · Apple Secure Enclave") plus tokens, cost, and latency.
* **Conversation context** — the full thread is sent with each message, so the model follows the conversation.

## Privacy

Playground messages use the same **end-to-end encryption** as the API on the credits path: your prompt is sealed to the serving enclave in your browser, and the reply is sealed back to you. The network never sees plaintext, so **chat history is never stored server-side** — it lives only on your device.

## Playground vs API

The Playground is a convenience surface for humans. For apps and agents, use the [OpenAI-compatible API](/cloud/grid/api) — same models, same confidential path, programmatic.

<Note>Open the Playground from the dashboard under **Grid → Chat**. Connect a wallet to begin.</Note>
