Nano Banana 2 vs Grok Imagine: 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 2: Combine references into a scene and adapt it from a square post to a wide banner.

Grok Imagine: Create images from a description and choose the version around whether you need to edit an uploaded photo.

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

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 2

Combine references into a scene and adapt it from a square post to a wide banner.

Create from text or edit from images; request 1, 2 or 4 results.
1K, 2K or 4K; 15 aspect-ratio options including Auto and very wide or tall formats.
Fourteen references is a ceiling, not a recommendation for every task.
More pixels do not fix mixed-up characters or incorrect product geometry.

What to inspect with Grok Imagine

Create images from a description and choose the version around whether you need to edit an uploaded photo.

1.0: text with Speed or Pro priority, or editing one photo.
2.0: new images from text; Segment Edit starts from an eligible generated result. Five aspect ratios are available for generation.
Segment Edit is not ordinary uploading of an arbitrary photograph into version 2.0.
Inspect lettering, logos and small objects separately.

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 2 and Grok Imagine 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.
