## Why Nano Banana 2

Nano Banana 2 is a selectable image workflow whose live form owns the current prompt, reference, resolution, ratio, and output-count controls. Review every returned image.

### Text-led and image-led modes

Text mode starts from a required prompt. Image mode requires reference media plus a prompt, so choose the mode from the inputs available for the task.

### Up to four reference images

Image mode accepts one to four files. References condition the run but do not lock identity, products, text, background, or composition.

### 1K, 2K, and 4K output

The resolution control offers all three settings. Higher resolution changes requested output size, not factual accuracy or identity preservation.

### Ten ratios plus Auto

Text mode offers ten aspect ratios from 21:9 through 9:16. Image mode adds Auto so framing can follow the supplied source.

### One to four outputs with access rules

One output is available by default; counts two through four require paid-model rights according to the form. Review the updated credit estimate before submission.

### Explicit file, prompt, credit, and time limits

References must be JPEG, PNG, or WebP up to 10 MB, prompts allow 3,000 characters, and metadata starts at 4 credits with an estimated 60 seconds.

## How to use the current image form

Choose the input mode first, then use only the reference, resolution, ratio, and output-count options that remain visible.

### Choose text or image input

Use text mode for a prompt-only result. Use image mode when one to four JPEG, PNG or WebP references up to 10 MB should condition the output.

### Set resolution, ratio, and count

Choose 1K, 2K, or 4K, then a supported ratio. Counts two through four require paid-model rights as shown by the form.

### Generate, compare, and refine

Review returned images beside the submitted prompt, references, and settings, then change one instruction or reference before the next run.

## Who uses Nano Banana 2's 1K–4K output, and for what?

Designers, marketers, ecommerce teams, illustrators, and creators can use these candidate workflows to test reference, resolution, ratio, and output-count behavior; every result still needs review.

### Marketing layout concepts

Test poster, ad, and social-layout ideas, then verify text, logos, product details, and disclosure requirements before publication.

### Product mockups

Use product references for studio or lifestyle concepts and reject results that alter packaging, labels, proportions, colors, or regulated claims.

### Concept art and illustration

Compare visual directions for characters, environments, and key art while checking composition and subject details against the prompt.

### Photo-change concepts

Use a clear source photo and one requested change, then compare the result for unintended changes to the subject, lighting, background, and crop.

### Recurring-character studies

Supply consistent references to test poses or outfits, but reject identity drift rather than claiming guaranteed subject consistency.

### Resolution and batch comparisons

Hold prompt and references constant while comparing output size or count, then record delivered dimensions, artifacts, and debit.
