Be a bit careful playing with this one. I tried this:

  curl -s -X POST \
    "https://generativelanguage.googleapis.com/v1beta/models/gemini-2.0-flash-preview-image-generation:generateContent?key=$GEMINI_API_KEY" \
    -H "Content-Type: application/json" \
    -d '{
      "contents": [{
        "parts": [
          {"text": "Provide a vegetarian recipe for butter chicken but with chickpeas not chicken and include many inline illustrations along the way"}
        ]
      }],
      "generationConfig":{"responseModalities":["TEXT","IMAGE"]}
    }' > /tmp/out.json

And got back 41MB of JSON with 28 base64 images in it: https://gist.github.com/simonw/55894032b2c60b35f320b6a166ded...

At 4c per image that's more than a dollar on that single prompt.

I built this quick tool https://tools.simonwillison.net/gemini-image-json for pasting that JSON into to see it rendered.
