Recipes for Runway Gen-4 Image Turbo

Each request below is generated from what Runway Gen-4 Image Turbo serves on NinjaChat today — the same capabilities and parameters that GET /models reports — so it runs as written with your key.

Edit an image

This model works from an input image: pass the photo and describe the change.

# export NINJACHAT_API_KEY="nj_sk_..."   (Developers → Keys)
curl https://www.ninjachat.ai/api/v1/images/generations \
  -H "Authorization: Bearer $NINJACHAT_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "runway-gen4-image-turbo",
    "prompt": "same product, now on a marble counter with morning light",
    "image": "https://example.com/espresso.jpg",
    "size": "1920x1920"
  }'
  • image is required on this model — a request without it is rejected with a 400 before anything is billed.
  • Write the prompt as the change you want, not a full re-description of the photo; the reference already carries subject, framing, and palette.
  • storage is optional and defaults to "durable". Set it to "provider" only when lower response latency matters more than receiving a permanent NinjaChat URL.
