+description: Configure Phase Router as a custom endpoint in LibreChat.
+---
+
+[Phase Router](https://router.phase.xyz) is an OpenAI-compatible model router: about 400 models (open models such as DeepSeek, Qwen, Llama, gpt-oss, Kimi and GLM, plus Claude models) behind one base URL and one API key. Each response reports the model that ran and its price in `usage.cost`.
+
+## Get an API key
+
+Create an API key (`phk_...`) in the [Phase Router dashboard](https://router.phase.xyz/dashboard). Add it to your `.env` file:
+
+```bash filename=".env"
+PHASE_API_KEY=your-api-key
+```
+
+## Configuration
+
+Add the endpoint to the `custom` list under `endpoints` in your `librechat.yaml`. If your file already has an `endpoints.custom` list, paste only the `- name:` entry into it, keeping the same indentation:
+
+```yaml filename="librechat.yaml"
+endpoints:
+  custom:
+    - name: "Phase Router"
+      apiKey: "${PHASE_API_KEY}"
+      baseURL: "https://router.phase.xyz/v1"
+      models:
+        default:
+          - "auto"
+          - "gpt-oss-120b"
+          - "deepseek-v3.2"
+        fetch: true
+      titleConvo: true
+      titleModel: "gpt-oss-120b"
+      modelDisplayLabel: "Phase Router"
+```
+
+To let each user supply their own key through the LibreChat UI instead of reading one from `.env`, set `apiKey: "user_provided"`.
+
+## Notes
+
+- With `fetch: true`, LibreChat loads the model list from Phase Router's OpenAI-compatible `/v1/models` endpoint. The `default` array is only the initial selection.
+- The model `auto` lets the router pick a model for each request; any model can also be called by its id from the [model catalog](https://router.phase.xyz/models).
+- See the [Phase Router docs](https://router.phase.xyz/docs) for prices, limits and the full API reference.
