# GPT Image 2 vs Nano Banana 2

Both models can generate and edit images in Mixer AI. This comparison also has unusually clean evidence: A direct test ran GPT Image 2 and Nano Banana 2 through the same architecture tasks and showed how the outcome changed when the prompt became more explicit.

## Key differences

Both support text and image workflows up to 4K in Mixer AI; GPT Image 2 accepts up to 16 input photos and Nano Banana 2 up to 14.

In one side-by-side test, Nano Banana 2 did better on the simple exterior and floor-plan task, while GPT Image 2 was preferred in separate people and interior-mood checks.

The test also showed prompt sensitivity: Nano Banana 2 needed an explicit instruction not to alter the camera angle in one exterior run.

## What the direct test actually showed

These are observations from one architecture test, not a universal model ranking.

- With the same simple exterior prompt, the reviewer saw more varied vegetation and clearer roof shingles from Nano Banana 2; GPT Image 2 showed repeated-looking textures.

- With a more detailed prompt, Nano Banana 2 produced a strong image but changed the viewpoint. A retry with an explicit instruction not to alter the camera angle fixed it.

- In the people test, the reviewer gave the round to GPT Image 2 because the Nano Banana 2 scene felt emptier and the mood was weaker.

- For a floor plan generated from a viewport, Nano Banana 2 preserved the object count more accurately and won that round in the review.

## Where the result changes

The same video does not reduce the comparison to one winner. Some interior tasks were close, while other rounds split between the two models.

- A simple prompt and a detailed prompt changed the relative result on the same exterior.

- Geometry and viewpoint preservation need to be checked separately from materials, lighting and overall realism.

- The reviewer's own closing point was task-dependent: one tool did better in one case, the other in another.

## Limits of this comparison

The test used a third-party interface. The specification table above reflects the current Mixer AI product instead; external controls shown in the video are not assumed to exist here. For a real project, run the same input and prompt through both models rather than treating one round as a general verdict.

## FAQ

Which model won the full architecture test?

There was no single overall winner. Nano Banana 2 took several exterior and floor-plan checks; GPT Image 2 was preferred for separate people and interior-mood tasks, while some interiors were close.

Can both models edit uploaded images in Mixer AI?

Yes. The current Mixer AI interface supports generation and editing for both.
