What is Nano Banana (Gemini 2.5 Flash Image)?
Nano Banana is the internal code name for Google’s Gemini 2.5 Flash Image, a multimodal AI image generation model launched on August 26, 2025. Combining advanced text understanding with powerful image generation, it significantly enhances creative efficiency. It excels in maintaining character consistency, multi-image synthesis, precise local editing, and logical reasoning, addressing common pain points in earlier AI image generation, such as inconsistent facial expressions, illogical scenes, or unrealistic details.
Before Nano Banana, AI-generated images often suffered from distorted faces, uncoordinated compositions, or violations of real-world logic (e.g., incorrect shadows or proportions). Gemini 2.5 Flash Image resolves these issues, making it ideal for tasks like background replacement, outfit changes, multi-turn dialogue-based editing, and creating DIY picture books or comics.

Key Features of Nano Banana
Natural Language Editing
No need for complex selections or professional tools. The model can understand and interpret prompts given in natural language. Nano Banana performs efficient real-time editing that can be seen almost instantly.
High Character Consistency
Maintains consistent facial features, hairstyles, expressions, and poses across multiple edits. For example, upload a selfie and request “change the background to a beach” or “swap the outfit for a blue dress,” and the output preserves the subject’s original appearance.
Image Blending
With Nano Banana, you can simply import multiple photos, type in the prompt to adjust light, shadows, or backgrounds, and let Gemini 2.5 Flash Image merge them into one image. It will ensure stylistic coherence and narrative alignment.
AI Figure Generation
This is one of Nano Banana's most popular features. It can transform real photos into chibi figurines, PVC models, or anime character styles, instantly making the photos more entertaining and valuable for collection.

Limitations of Nano Banana
- Consistency and Quality Degradation: The visual quality of the output can degrade quickly after a couple of editing turns in the same conversation.

- Limited Creativity: Compared to other models like Imagen 4 and GPT-1, its creative output can be limited.
- Repetitive Outputs: After a failed edit, it may continue to output the same image, requiring the user to start a new chat or change the prompt significantly to achieve the desired result.
- Watermarks: Images generated or edited within Gemini will have a visible watermark, as well as an invisible SynthID to indicate they are AI-generated.
- Language Support: While it works well with English and Chinese prompts, other languages may not have the same level of support.
