const merlin = new Merlin({ merlinConfig: { apiKey } });

async function createCompletion() {
  try {
    const completion = await merlin.chat.completions.create({
      messages: [
        {
          role: "user",
          content: [
            {
              type: "text",
              text: "What’s in this image?",
            },
            {
              type: "image_url",
              image_url: {
                url: "https://upload.wikimedia.org/wikipedia/commons/thumb/d/dd/Gfp-wisconsin-madison-the-nature-boardwalk.jpg/2560px-Gfp-wisconsin-madison-the-nature-boardwalk.jpg",
              },
            },
          ],
        },
      ],
      model: "gpt-4-vision-preview", // Adjust model as needed
    });

    console.log(completion.choices[0].message.content);
  } catch (error) {
    console.error("Error creating completion:", error);
  }
}

createCompletion();
