Nano Banana vs Z-Image: technical and visual comparison

This compares two models that are available in the current Mixer AI catalog. The table below is built from current product controls, while the visual section shows what to inspect with the same inputs and prompt instead of inventing one universal winner.

Key differences

Nano Banana: Change a photo's background, clothing or setting without describing the whole scene from scratch.

Z-Image: A new image from a short description, for concepts, illustrations and first visual experiments.

Start with the specification table: it reflects current modes, input media, duration, resolution, aspect ratios and a normalized price where a fair comparison is possible.

Specifications

Spec	Nano Banana	Z-Image
Generation modes	from text / photo editing	from text
Input photos	up to 10	No
Resolutions	~1K	No separate selector
Aspect ratios	9:16 / 16:9 / 1:1 / auto / 2:3 / 3:2 / 3:4 / 4:3 / 5:4 / 4:5 / 21:9	9:16 / 16:9 / 1:1 / 4:3 / 3:4
Prompt limit	5,000 characters	1,000 characters
Price per image (different settings)	5 coins · Auto	1 coins · Auto

There is no shared resolution for a direct price comparison, so each price includes its setting and is not highlighted as cheaper.

What to compare visually

For a fair A/B test, use the same prompt, aspect ratio and references. Inspect more than overall style: object preservation, geometry, faces and hands, fine detail, text in the frame and unintended changes during editing.

What to inspect with Nano Banana

Change a photo's background, clothing or setting without describing the whole scene from scratch.

Text or photos, with up to 10 input images.
11 aspect-ratio options including Auto; roughly 1K output without a separate 2K or 4K setting. Request 1, 2 or 4 results.
Even a short instruction cannot guarantee preservation of a face or fine detail.
This version does not offer a separate 4K output setting.

What to inspect with Z-Image

A new image from a short description, for concepts, illustrations and first visual experiments.

New image generation from text only.
Five aspect ratios and prompts up to 1000 characters.
This model page does not edit uploaded photos.
Text alone may not reproduce a particular face, package or brand mark accurately.

How to run a fair comparison

Lock one prompt, aspect ratio and a duration or resolution that both models actually support.
If input modes differ, compare the shared workflow first and test each model's extra controls separately.
Run more than one attempt: a single output reflects one seed, not the model's overall consistency.
Score prompt adherence, visual artifacts, reference preservation and the cost of the setting you would really use separately.

FAQ

How should I compare Nano Banana and Z-Image fairly?

Use a workflow both models share, keep inputs and prompt identical, then run several generations. Compare prompt adherence, visual consistency and the price of the setting you need as separate dimensions.

Are both models available in Mixer AI?

Yes. This page is generated only for models in the current public Mixer AI catalog; if a model leaves the catalog, the automated comparison must stop passing validation.

Which model is better?

There is no universal answer. First eliminate a model that cannot accept the input, duration, resolution or format you need, then compare outputs on your own scene. The table highlights only measurable advantages in individual specifications.
