Imagen 4 or FLUX: which to choose for an image from a description?

Both brands have several options for generating from text and almost identical aspect ratios. The deciding difference is outside this table: Imagen 4 has no mode for editing an existing image, and FLUX does. If you may ever need to rework an image you've already made, FLUX stays in the game, Imagen 4 doesn't.

What is Imagen better at?

Imagen 4 offers three tiers — fast, standard and highest. The same prompt goes through all three and the difference is visible without switching brands.

Imagen 4 states a prompt limit. You know how far the model reads — more useful than a field with no stated limit, where you don't know where your writing starts to be wasted.

The set of aspect ratios covers ad and social formats.

What is FLUX better at?

FLUX has a mode for editing an existing photo, and with the most input images among several of the image brands here. That is one whole mode more than Imagen 4.

The fast FLUX variant is one of the cheapest ways to test an idea. When you're searching for a composition, that's the number that matters.

FLUX also has several variants when generating, meaning price tiers exist here too.

Where does each of the two fall short — Imagen and FLUX?

Where Imagen 4 loses. It has no image-to-image mode at all. That's not a setting that's missing — an entire workflow doesn't exist. As soon as you want to rework a frame, you'll switch brands and, with them, the character of the image.

Where FLUX loses. It doesn't state a prompt limit for generation, so there's no way to know how far the model reads. And for editing it has only one variant — there's no cheap tier for test runs, and with editing it's exactly the test runs that are expensive.

How to choose between Imagen and FLUX?

If the work ends with generating — Imagen 4 is a solid choice. If you'll be reworking the image after generating — FLUX, so you don't switch brands in the middle of a project.

Questions and answers

No. On the platform, Imagen 4 only has text-to-image mode. To edit an existing photo, see FLUX, Nano Banana, Seedream, GPT Image or Qwen Image.

Which of the two is better for realistic people?

Both make convincing people from a simple description. A complex scene with several people stays hard for both — in that case you work in steps.

Do the three steps of Imagen 4 matter?

Yes, for the final shot. When looking for a composition, the fastest option is enough and saves credits.
