Google’s Nano Banana (officially Gemini 2.5 Flash Image) is transforming AI image editing. Its advanced capabilities allow users to achieve consistent, high-quality results, but many are unsure which prompts work best. Based on official sources and community reports, Nano Banana’s main strengths include multi-round refinement, subject consistency, flexible scene placement, and realistic composites, though some basic editing functions like precise cropping remain limited.
Below is a comprehensive collection of prompts, organized into 11 practical categories. Primarily in English; translation tools can convert them to Chinese if needed.
- Storyboard & Character Consistency Ideal for sequential frames featuring the same character in various environments.
