Nano Banana Pro
Nano Banana Pro is the premium Gemini choice for images that need more realism, stronger face detail, and a more finished look. Its DayGen budget supports up to six object or general references, five Avatar/Character references, and three style-role references.
Best for
- quality
- consistency
- edits
- realism
Use when
- You are generating a hero image, profile image, campaign visual, or final concept.
- The subject has important facial features, skin texture, small details, or product markings.
- You want the Gemini family but need more quality than the fast model.
- You are editing or resizing an asset that already has a strong direction.
Avoid when
- You only need rough ideation; use Nano Banana 2 or Krea Turbo first.
- The work is typography-first; compare Ideogram 4.0 or Recraft.
