+title: Heabsy
+description: Configure Heabsy as a custom endpoint in LibreChat.
+---
+
+[Heabsy](https://heabsy.com/platform) serves open models through an OpenAI-compatible API. Models in its EEA tier run on dedicated GPUs inside the European Economic Area with zero data retention; the [model catalog](https://heabsy.com/models) marks which models run there.
+
+## Get an API key
+
+Get an API key in the [Heabsy console](https://platform.heabsy.com); accounts are opened on request at [heabsy.com/contacts](https://heabsy.com/contacts). Add the key to your `.env` file:
+
+```bash filename=".env"
+HEABSY_API_KEY=your-api-key
+```
+
+## Configuration
+
+Add the endpoint under `endpoints.custom` in your `librechat.yaml`:
+
+```yaml filename="librechat.yaml"
+    - name: "Heabsy"
+      apiKey: "${HEABSY_API_KEY}"
+      baseURL: "https://api.heabsy.com/v1"
+      models:
+        default: ["qwen38"]
+        fetch: true
+      titleConvo: true
+      titleModel: "current_model"
+      modelDisplayLabel: "Heabsy"
+```
