    {
      model: 'gpt-3.5-turbo',
      messages: [
        {
          role: 'user',
          content: prompt
        }
      ]
    },
    {
      headers: {
        Authorization: `Bearer ${process.env.OPENAI_API_KEY}`
      }
    }
  );
  return response?.data?.choices?.[0]?.message?.content;
};
