+## Using Custom OpenAI Endpoints
+
+Goose supports using custom OpenAI-compatible endpoints, which is particularly useful for:
+- Self-hosted LLMs (e.g., LLaMA, Mistral) using vLLM or KServe
+- Private OpenAI-compatible API servers
+- Enterprise deployments requiring data governance and security compliance
+- OpenAI API proxies or gateways
+
+### Configuration Parameters
+
+| Parameter | Required | Description |
+|-----------|----------|-------------|
+| `OPENAI_API_KEY` | Yes | Authentication key for the API |
+| `OPENAI_HOST` | No | Custom endpoint URL (defaults to api.openai.com) |
+| `OPENAI_ORGANIZATION` | No | Organization ID for usage tracking and governance |
+| `OPENAI_PROJECT` | No | Project identifier for resource management |
+
+### Example Configurations
+
+<Tabs groupId="deployment">
+  <TabItem value="vllm" label="vLLM Self-Hosted" default>

+    ```sh
+    OPENAI_HOST=https://your-vllm-endpoint.internal
+    OPENAI_API_KEY=your-internal-api-key
+    ```
+  </TabItem>
+  <TabItem value="kserve" label="KServe Deployment">
