What Is Imagen 4?

Imagen 4 was the workhorse of Google's previous image API, which closed on 17 August 2026. This page stays online so that people still searching the name get an accurate account of where things stand and a migration route, instead of a 404. Its functional successor is the Nano Banana 2 family.

What Is Imagen 4 Best For?

  • Understanding what the model did
  • Mapping an Imagen integration onto Nano Banana

How to Use Imagen 4

  1. Point calls at Nano Banana 2 (gemini-3.1-flash-image).
  2. Imagen's aspect ratio parameter remains compatible on Nano Banana 2.
  3. Where you previously added a separate upscaling step, switch straight to the 4K tier.

Imagen 4 Test Results

Testing in progress

Every model runs the same eight-category prompt set — portrait, product, poster text, anime character, interior, multi-reference, image editing and character consistency — recording generation time, success rate, text accuracy and identity retention. That run has not finished for Imagen 4, so this page shows no scores. We do not publish numbers we have not measured.
