    <Steps>
      <Step title="Install the package">
        Install the OpenAI Python library using pip:

        ```bash theme={null}
        pip install openai
        ```
      </Step>

      <Step title="Set your API key">
        Export your OpenAI API key as an environment variable:

        ```bash theme={null}
        export OPENAI_API_KEY='your-api-key-here'
        ```

        <Info>Get your API key from the [OpenAI Platform](https://platform.openai.com/settings/organization/api-keys)</Info>
      </Step>

      <Step title="Make your first API call">
        Create a simple script to generate text using the Responses API:

        ```python theme={null}
        from openai import OpenAI

        client = OpenAI()

        response = client.responses.create(
            model="gpt-5.2",
            instructions="You are a helpful assistant.",
            input="Explain the theory of relativity in simple terms."
        )

        print(response.output_text)
        ```
