# Nano Banana 2 vs Seedream 5.0 Pro: model comparison

Both models are currently available in Mixer AI and both support generation plus editing. Nano Banana 2 accepts up to 14 images and exposes 1K/2K/4K; Seedream 5.0 Pro accepts up to 10 images and exposes 1K/2K. The evidence comes from separate reviews, so the page does not pretend these observations form a controlled head-to-head.

## Key differences

Nano Banana 2: up to 14 input images, 15 aspect options and 1K/2K/4K.

Seedream 5.0 Pro: up to 10 input images, eight aspect ratios including 21:9, and both 1K/2K for every ratio.

The tests show Nano Banana 2 preserving structure well in a floor-plan task, while Seedream Pro showed strong lighting logic and material-aware text rendering, with concrete errors on both sides.

## Nano Banana 2: geometry and people

- On a detailed architecture prompt, Nano Banana 2 initially changed the viewpoint; an explicit instruction not to alter the camera angle was needed on the retry.

- In the people test, the reviewer found the Nano Banana 2 scene emptier and weaker in mood than the alternative result.

- In the floor-plan task, Nano Banana 2 preserved object counts more accurately and won that round for structural precision.

## Seedream 5.0 Pro: lighting and product text

- In a welding scene, the reviewer found the single-source lighting logic convincing while still pointing out an inaccurate shadow.

- Text on a bottle looked clean at normal viewing size but became visibly rougher under close inspection.

- In a packaging task, the text looked cleaner but the model did not follow the entire compound prompt and omitted requested graphic marks.

## What can actually be compared

These reviews do not support an overall winner because the tasks and interfaces differ. They do show why both models need separate checks for geometry preservation, lighting logic, small text and full multi-part prompt adherence.

- Nano Banana 2 exposes more input images and 4K in Mixer AI.

- Seedream 5.0 Pro performed strongly in several lighting checks but still produced specific errors.

- Neither source supports a universal advantage across all image tasks.
