gemini-3-pro-image is the premium Nano Banana option on YingTu. It is intended
for work where layout complexity, text rendering, professional mockups, or
high-resolution delivery matter more than minimizing request cost.
Google positions Nano Banana Pro as a reasoning-driven generator and editor for
professional design, high-fidelity product mockups, and factual visualizations.
That is upstream product positioning, not a guarantee that it wins every prompt.
See the official model page.

Do not pay the Pro premium based on the name alone. Run the same brief and
source images through Flash and Pro, then compare the outputs against your
acceptance criteria and retry budget.
