Nano Banana
Google's original Gemini-based image model. Cheapest tier in the family — flat $0.039 per image. Strong photorealism, fast turnaround.
Nano Banana guideVerified
Google's flagship image generation. Nano Banana Pro is the current best — strong scene composition, instruction-following, and complex multi-subject layouts.
Strengths
- Best instruction-following for image models — Nano Banana actually places objects where you say.
- Strong on complex scenes with multiple subjects, relationships, spatial layout.
- Edit variant (nano-banana-edit) supports up to 14 reference images.
- Reliable for product / commercial work.
Weaknesses
- Aesthetic less distinctive than Midjourney (defaults to a Google-style polish).
Best for
- Product photography with specific layouts ("bottle on left, ice cubes right")
- Multi-subject scenes ("man holding a child, dog at his feet, mountains behind")
- Commercial / e-commerce work
Prompting tips
- Be EXPLICIT about object placement and relationships.
- Numeric counts work ("three apples on the table") better than vague ("some apples").
