The family's daily default

Most marketing, product, and content workflows start here. Step up to Ultra when alignment must be tighter; drop to Fast for high-volume drafts.

In-image text you can actually read

Google's June and August 2025 announcements both lead with "major text rendering gains vs Imagen 3" — which is why official demos are console-warning comics and metal-headline posters.

Up to 2K, GA-ready

Same up-to-2K support as Ultra — enough for marketing assets and zooming into complex compositions.

Three tiers, one decision

Fast for volume, standard Imagen 4 as daily workhorse, Ultra when alignment and detail decide delivery.

What the model actually delivers

Multi-panel comics with readable console text, vintage postcards, summit photography, alien landscape fashion — all from Google's Imagen 4 launch and GA announcements.

Where Imagen 4 shines

Balanced instruction following, in-image text, up-to-2K photoreal detail, cross-style coverage, and SynthID by default.

Instruction following under multiple constraints

Three panels, four verbatim in-image text blocks, specified wardrobe, specified light direction — Ultra is the tier built to satisfy all of them in one render.

In-image text

Console warnings, postcard headlines, comic sound effects, metallic poster type. Official demos lean on text because it's the biggest gain vs Imagen 3.

Photoreal and editorial detail

Summit sunrise and fashion stills need natural light, real skin, fabric volume, and cinematic color — without quietly dropping half your prompt.

Up to 2K output

Enough for marketing assets and complex compositions — confirmed for both Ultra and standard in Google's August 2025 GA announcement.

Range without switching models

Vintage comics, old travel graphics, lifestyle photography, surreal concept fashion — illustration and photography on one interface.

SynthID by default

Every Imagen 4 family image carries Google's invisible SynthID watermark — provenance travels with the file without affecting visible design.

One model, eight production workflows

The jobs Google chose to demo, plus everyday scenes where strict prompt following quietly saves three rerolls.

Multi-panel narrative comics
