I'm having the same issue exactly that @Object documented here, back in May 2025: https://discord.com/channels/595317990191398933/1105477009964027914/1375585311647862784 Any ideas from the CF team?

Hey @robinsloan , I think the schema incorrectly shows a single object being valid for the content. The content field can either be a plain string or an array of content. You'll want the latter for images, e.g.

{
  "messages": [
    {
      "role": "user",
      "content": [
          {
            "type": "text",
            "text": "What is in this image?"
          },
          {
            "type": "image_url",
            "image_url": {
          "url": "data:image/png;base64,<base64-encoded image>"
            }
          }
        ]
    }
  ]
}

{
  "messages": [
    {
      "role": "user",
      "content": [
          {
            "type": "text",
            "text": "What is in this image?"
          },
          {
            "type": "image_url",
            "image_url": {
          "url": "data:image/png;base64,<base64-encoded image>"
            }
          }
        ]
    }
  ]
}
