+[Auxen](https://auxen.ai) hosts per-customer **dedicated** LLM endpoints (Llama 3.1/3.2, Qwen 2.5, Mistral, Gemma 2, Mixtral, Phi-3, Command R) on stable HTTPS URLs with an OpenAI-compatible `/v1/chat/completions` API. Each Auxen instance is a dedicated GPU billed per-minute of runtime, not per token.
+
+<Info>
+  Provision an instance from the [Auxen dashboard](https://auxen.ai). You will be issued two values:
+
+  - A per-instance **base URL** of the form `https://api.auxen.ai/v1/inst_xxx/v1`
+  - A per-instance **API key** prefixed `auxk_`
+</Info>
+
+## Configuration

+<Tabs>
+   <Tab title="YAML">
+   ```yaml title="config.yaml"
+   name: My Auxen Config
+   version: 0.0.1
+   schema: v1

+       model: llama-3.1-8b
+       apiBase: https://api.auxen.ai/v1/inst_xxx/v1

+       }
+     ]
+   }
+   ```
+   </Tab>
+</Tabs>
+
+The `model` field should match the model your Auxen instance is serving. Each Auxen instance is provisioned with one model at creation time.
