Imagen 4 Ultra on Hermosso
Google's top photoreal tier: maximum detail for images that pass as photographs.
What Imagen 4 Ultra does best
Maximum photoreal detail
Imagen 4 Ultra is Google's top photoreal tier — and our most detailed photoreal engine. Fine mechanical texture, skin, depth of field: the details that separate a render from a photograph are where it spends its budget.
The top of a clean lineup
Google's Imagen 4 family is the studio's clean all-rounder line: Imagen 4 handles fast everyday generation at 50 credits, and Ultra is the tier you climb to when the image has to survive a close look.
Text-to-image, honestly
One caveat worth knowing: Imagen 4 Ultra is text-only — it doesn't accept reference images. If your job starts from an existing photo, pick a reference-capable model like Nano Banana 2 or Seedream 5 Pro instead.
