What is Imagen 4 Fast?

Imagen 4 Fast is Google's quick text-to-image model, built for everyday work where speed and price matter. Our samples show it handling a lettered poster, an isometric scene, product shots and a landing page mockup.

Can Imagen 4 Fast edit my photos or use reference images?

No. Imagen 4 Fast makes images from a text prompt only. If you need to edit a photo or keep a product consistent, pick a model that takes references, such as GPT Image, Nano Banana or Seedream. Since credits are shared, you can switch with one field.

How much does Imagen 4 Fast cost?

3 credits per image. Plans start at $9/month for 1,000 credits, enough for about 333 images a month.

Can I use Imagen 4 Fast in Claude, ChatGPT or Cursor?

Yes. Connect AiWings once as a connector in Claude, a plugin in ChatGPT, or an MCP server in Cursor, then ask for an image and name the model, for example “use Imagen 4 Fast”. The image shows up right in the chat.

What resolutions and aspect ratios does it support?

1K (about 1,024 px), in 1:1, 9:16, 16:9, 3:4 and 4:3. If you ask for a ratio it doesn't list, AiWings uses the closest one.

What's the difference between Imagen 4 Fast, Imagen 4 and Imagen 4 Ultra?

All three are Google image models on AiWings. Imagen 4 Fast (3 credits) is the quickest and most affordable, Imagen 4 (5 credits) is the balanced choice with 2K output, and Imagen 4 Ultra (8 credits) is the top-fidelity one. Credits are shared, so you can try all three on the same prompt.
