# Try models and routing in the Playground

> Use the Aria Compute Playground for AFM chat, ROUTER decision routing (three *-auto entrypoints), and AGENT sessions.

The **Playground** is a separate web app mounted on the Aria Compute site at `/playground`. It is not part of this Mintlify docs site; open it from the marketing site and keep your docs tab for reference.

| Site          | URL                                                                      |
| ------------- | ------------------------------------------------------------------------ |
| International | [https://ariacompute.com/playground](https://ariacompute.com/playground) |
| China         | [https://ariacompute.cn/playground](https://ariacompute.cn/playground)   |

Pass `?lang=` to match the UI language you selected on the site (for example `/playground?lang=zh`).

## What you can try

* **AFM Base Model** — chat against an OpenAI-compatible AFM endpoint.
* **ROUTER Decision Routing** — same chat UX through `aria-router`, with strategy choices for Semantic / Agent / Decision Model. Gold virtual models:
  * `ariacompute/semantic-auto`
  * `ariacompute/agent-auto`
  * `ariacompute/afm-d-auto`
* **AGENT** — sessions against the cloud agent runtime (`aria-agent-cloud`).

ROUTER and AGENT playgrounds use sandboxed backend pools so concurrent users do not share router or agent state.

## Account

Some Playground actions require a signed-in Aria Compute account on the same site (`.com` or `.cn`). Use [Authentication](/authentication) and your region’s wallet / API keys as needed. See [Sites & regions](/concepts/sites-regions) and [Serve (site)](/concepts/serve).
