# Serve: the Aria Compute public site

> What the Serve-powered marketing and account site provides: products, downloads, docs, playground, and region-specific accounts.

**Serve** is the public Aria Compute website and account plane (the `serve` product). It powers `ariacompute.com` and `ariacompute.cn` — marketing pages, downloads, documentation links, and signed-in account features. It is **not** the PIN post-training API process or the ROUTER/AGENT runtimes themselves.

## Two sites

|                           | International          | China                 |
| ------------------------- | ---------------------- | --------------------- |
| Site                      | `ariacompute.com`      | `ariacompute.cn`      |
| Docs                      | `docs.ariacompute.com` | `docs.ariacompute.cn` |
| Accounts / wallets / keys | Separate               | Separate              |

Details: [Sites & regions](/concepts/sites-regions).

## What you find on the site

* **Products** — Models, Engine, Router, Agent (and related CTAs).
* **Models catalog** — including decision models (AFM-D Encoder / Decoder). See [Models](/concepts/models) and [AFM-D](/concepts/afm-d).
* **Download** — Engine, Router, and other release assets (GitHub on `.com`, Gitee mirror on `.cn`). See [Downloads](/resources/downloads).
* **Docs** — this documentation set.
* **Playground** — interactive AFM / ROUTER / AGENT trials at `/playground`. See [Playground](/guides/playground).
* **Account** — registration, API keys, wallet, invoices (region-specific).

## How Serve relates to APIs

| Surface                                          | Role                                                |

| [PIN API](/api-reference/pin/introduction)       | Post-training / jobs / GPU nodes                    |
| [ROUTER API](/api-reference/router/introduction) | Self-hosted inference gateway                       |
| [AGENT API](/api-reference/agent/introduction)   | Cloud agent runtime                                 |
