When to Use Pro

Choose Nano Banana Pro over standard Nano Banana when:

Creating marketing materials with typography
Complex multi-element scenes
Higher quality output is needed
You need better prompt understanding

For simple image generation without text, standard Nano Banana is faster and more cost-effective.
