What Is Nano Banana Pro?
Nano Banana Pro is the most expensive and most dependable tier, and the difference shows up in three places: images with a lot of text (posters, infographics), characters that must stay identical across several reference images, and products or spaces that need structurally correct geometry. If the text has to be right on the first try, Pro usually means fewer reruns than the standard tier.

Nano Banana Pro Settings Explained
Text Layout
Declaring text density up front makes the model reserve space, which cuts down on clipped or mushy lettering.
Reference Images
Up to 6 — enough to supply several angles of one character.

Nano Banana Pro Test Results
Testing in progress
Every model runs the same eight-category prompt set — portrait, product, poster text, anime character, interior, multi-reference, image editing and character consistency — recording generation time, success rate, text accuracy and identity retention. That run has not finished for Nano Banana Pro, so this page shows no scores. We do not publish numbers we have not measured.
Nano Banana Pro Limitations
- Highest cost per image — not for batch drafting
- Maximum of 2 images per run
- Slower than Lite and the standard tier

Frequently Asked Questions
When is Pro worth it over the standard tier?+
When the image contains text that has to be readable, when brand guidelines are involved, or when you have more than 4 reference images. For stylised illustration the standard tier is usually enough.
Is the text always correct?+
No. Long sentences and non-Latin scripts can still break. For critical copy, overlay the final text in a design tool.
