        ```

     4. In **API protocol**, select `openai-completions`.

     5. In **API key**, paste your FriendliAI API key.

     6. Click **Fetch available models**. Then, click **Add selected**.

     7. Click **Create provider**.

  4. When you're ready to send a prompt, select a model. For example, select **zai-org/GLM-5.3**.
