# Aria Compute ROUTER: OpenAI-compatible inference gateway

> Aria Compute ROUTER is a self-hosted inference gateway with two routing modes: semantic (YAML v0.3 recipe) and agent (builtin tool-loop). Explore data-plane and management-plane endpoints.

Aria Compute ROUTER is a self-hosted OpenAI-compatible inference gateway. It provides two parallel routing engines: a **semantic router** that matches requests against a YAML v0.3 recipe using routing signals, and an **agent router** that runs an in-process builtin tool loop. The router exposes a data plane for inference clients and a management plane for operators.

The data plane implements the standard OpenAI `/v1/models` and `/v1/chat/completions` endpoints, so existing SDKs work without changes. The management plane covers authentication, routing configuration, cost tracking, and key management under `/v1/router/*`.

Shared provider models and hard constraints (cost, latency, capability) are evaluated at request time. You configure entrypoints, providers, and routing rules in a YAML v0.3 config file that the router reloads dynamically.

```text theme={null}
http://<router-host>:8080
```

The router is self-hosted. Replace `<router-host>` with the host where your router instance is running.
