Imagen 4 image generator
By Yuvraj Singh·Founder, Leaxor·Reviewed
Imagen 4 Ultra is Google's photoreal image model, and Ultra is the highest-fidelity variant of the four rather than the fast one.
What it is known for is realism in the difficult places — skin, hair, fabric, natural light. Those are the details that give a generated image away, and it handles them better than most.
It costs three credits here, which puts it in the middle of the lineup: three times Flux 2 Pro, half of Nano Banana Pro.
No Google account, no ImageFX, no waitlist. It sits in the same prompt box as the other six.

How it works
- 1
Select Imagen 4 Ultra
One of seven models in the same prompt box, marked as Google's photoreal option. Nothing else about the workflow changes.
- 2
Write for a camera
Imagen responds to photographic specifics — time of day, light source, lens, distance. Vague quality adjectives do far less than one concrete detail about how the scene is lit.
- 3
Use it where realism is the point
People, skin, hair, fabric, food, natural light. On flat or graphic subjects the extra credits buy very little over the one-credit models.
- 4
Pick the ratio the image is for
16:9 for thumbnails, 9:16 for stories, 1:1 for social, 3:2 classic. Each is a real resolution rather than a crop.
- 5
Compare against Flux once
Run one prompt on both. Four credits settles whether your subject matter is one where Imagen's realism is worth the difference, and the answer tends to hold for everything you make.
What you can make with Imagen 4
Human subjects that must not look generated
Faces, hands and skin are where cheap models fail most visibly. This is the case where three credits is straightforwardly worth it rather than arguable.

Fabric, food, weather, water. Subjects whose realism depends on how light behaves rather than on drawing, which is exactly what Imagen was tuned for.
How to make your videos look recognisably yoursReference frames for an illustrated video
A realistic reference to anchor a scene before it is stylised. Generating the real version first often produces a better illustrated one.

Flux 2 Pro: 1 credit ($0.10) per image. Credits are $0.10 each, minimum purchase 50 ($5.00).
Flux 2 Pro is one credit against three and is the better default for most photoreal work — sharper, cheaper, and good enough that the difference is invisible on a lot of subjects. Imagen 4 Ultra pulls ahead specifically on people and natural materials, where the small failures of a cheaper model are the ones viewers notice. If your subject is a person, the extra two credits are usually the right spend.
Imagen 4 vs Adobe Firefly
Firefly is bundled into Creative Cloud and is trained on licensed material, which for some teams is the whole decision and a genuinely strong reason to pick it. It also sits inside Photoshop, which nothing here replaces. The difference is the purchase: three credits an image with no subscription, against a plan billed monthly. We have not benchmarked Firefly's output against Imagen 4 and will not claim to.
Adobe FireflyWhen this is the right page
The realism specialist. Imagen 4 Ultra earns its three credits on human subjects and natural materials, where the failure modes of cheaper models are most obvious. For graphic or illustrated work it is the wrong tool — Recraft is built for design and costs less — and for images whose point is rendered type, Ideogram is the specialist.

Questions
Which Imagen version does Leaxor run?
Imagen 4 Ultra — the highest-fidelity variant, not the fast one. It is selectable directly in the model picker.
What does an Imagen 4 image cost here?
Three credits, which is $0.30 per image. Credits are $0.10 each with a minimum purchase of 50 ($5.00), so that is the smallest real first spend. Credits never expire and there is no subscription. That places it mid-range: dearer than Flux 2 Pro at one credit, cheaper than Nano Banana Pro at six.
Do I need a Google account or ImageFX?
No. It runs here in the browser with no Google sign-in, no ImageFX and no waitlist — which is the usual reason people look for another way to reach it.
What is Imagen 4 Ultra actually better at?
Photorealism on difficult subjects: skin, hair, fabric, food and natural light. These are the details that expose a generated image, and it handles them more reliably than the cheaper models here.
Is Imagen the best model on Leaxor?
No single model is. It is the strongest for photoreal human subjects; Ideogram beats it on text, Recraft on vectors, and Flux 2 Pro matches it closely on many subjects for a third of the price. Picking per image is the entire point of having seven.
Can I use the images commercially?
Yes — including thumbnails, channel art and client work. Generated images are yours to publish and monetise, with no stock licence to resolve.
What resolution do I get?
Real dimensions per aspect ratio rather than an upscaled square: 1344×768 for 16:9 thumbnails, 768×1344 for 9:16, 1024×1024 for square and 1216×832 for 3:2.
How does Imagen 4 compare to Nano Banana Pro?
Both are Google models and Nano Banana Pro is the newer, stronger one — it reasons about a prompt before drawing, and it costs six credits against three. Imagen 4 Ultra is the better value when you want Google's photoreal look without paying for the reasoning step, which is most photography-style work with no text in it. The three-credit gap is the whole decision.
What is Imagen 4 Ultra actually best at?
Photorealism with natural light. Skin, fabric, foliage and reflections come out closer to a photograph than to a render, which is what you want for lifestyle imagery and product shots. It is weaker on stylised or illustrated work — Recraft and Ideogram were built for that and cost less, so sending design work here pays a premium for a strength you are not using.
