Comparing Nano Banana Pro, Nano Banana, Flux Kontext, ChatGPT

November 25, 2025

Nano Banana Pro is finally out, and is getting great reviews from the community! We decided to test it against popular game art use cases to see how it does in comparison with Nano Banana, GPT and Flux Kontext. While Nano Banana Pro does certain things really really well, it still struggles with certain long-standing AI image edit problems, such as maintaining a consistent style, transferring a reference pose to an image, understanding left vs right etc. Read through to see our results.

(Hint: You can also run these tests yourself by going to the renderwolf app and using our image editing workflows! )

Pose Transfer

Winner: Nano Banana Pro (but only sometimes!) 

Maintaining a consistent art style through the editing process is critial for game art AI workflows. While Nano Banana Pro seems to nail the pose better than all the other editing models, it does lose art style consistency, surprisingly more often than its older version Nano Banana!

Left vs Right

Winner: None

Want to reliably ask AI to add an icecream cone to a character's right hand? You'll need to wait a bit longer, because Nano Banana Pro doesn't seem to have solved this problem that have plagued the older models either.

Style Transfer

And now for the big one. One-shot style transfer - i.e being able to generate an image in the art style of a reference image, without the complexity of fine-tuning your own models.

Winner: None (although ChatGPT is still  ahead of the rest)

Generating images in your own custom art style continues to require a fine-tuned model. Yes, it would be nice to provide a style reference image and have AI generate a new image in that exact style. But, we often hear from artists that the ability to fine-tune a model using their own art, with all the nuances that go into that art style is worth the effort. So maybe it isn't a big deal that this problem continues to elude the big models?

We are going to keep updating this page with more tests. Meanwhile, head over to the renderwolf app and run your own, because we have every one of these models under one roof, and even help you manage your game art in one place, fine-tune your own art style and much more!
