What is Imagen 3?

Imagen 3 is Google's dedicated photorealistic image model. While Gemini models are versatile across styles, Imagen 3 focuses on one thing: making images that look genuinely photographed.

When to Use Imagen 3

Product photography

E-commerce shots, product mockups, packaging visualisation. Imagen 3 handles materials, reflections, and lighting like a real camera would.

Lifestyle and editorial

Images that look like they came from a photoshoot. People in environments, action shots, candid moments.

Real-world scenes

Architecture, interiors, landscapes, food photography — anything that needs to look genuinely captured.

Inpainting tasks

Imagen 3's inpainting support means you can modify specific areas of an image while keeping the rest intact. Useful for:

  • Removing unwanted objects
  • Changing specific elements
  • Extending image boundaries

When NOT to Use It

  • Illustrations or stylised graphics — Use DALL-E 3 or Gemini
  • Text-heavy images — Use a Gemini Pro Image tier
  • Quick iteration — Use Gemini 2.5 Flash
  • Abstract or artistic work — Use DALL-E 3

Inpainting: Edit Specific Areas

Imagen 3's inpainting feature lets you modify parts of an image:

How it works

  1. Upload your image
  2. Describe what you want to change and where
  3. The model edits only that area, keeping the rest intact

Example prompts:

  • "Remove the person in the background on the right side"
  • "Replace the sky with a dramatic sunset"
  • "Change the wall colour to sage green"
  • "Add a plant in the empty corner"
