## Run the Example

<Steps>
  <Snippet file="create-venv-step.mdx" />

  <Step title="Install dependencies">
    ```bash theme={null}
    uv pip install -U agno aiohttp azure-ai-inference openai
    ```
  </Step>

  <Step title="Export environment variables">
    <CodeGroup>
      ```bash Mac/Linux theme={null}
      export AZURE_API_KEY="your_azure_api_key_here"
      export AZURE_ENDPOINT="your_azure_endpoint_here"
      export OPENAI_API_KEY="your_openai_api_key_here"
      ```

      ```bash Windows theme={null}
      $Env:AZURE_API_KEY="your_azure_api_key_here"
      $Env:AZURE_ENDPOINT="your_azure_endpoint_here"
      $Env:OPENAI_API_KEY="your_openai_api_key_here"
      ```
    </CodeGroup>
  </Step>

  <Step title="Run the example">
    Save the code above as `reasoning_model_stream_deepseek.py`, then run:

    ```bash theme={null}
    python reasoning_model_stream_deepseek.py
    ```
  </Step>
