Say No to Glitchy Art! The Ultimate Nano Banana 2 Prompt Guide You'll Ever Need

We've recently received numerous messages from fans saying that despite the hype around ​Nano Banana 2​, their generated images often look like an "abstract nightmare," plagued by various "broken" details. To help you overcome these hurdles, our editor has compiled this "foolproof" guide based on official Google documentation and expert community cases.

Before we delve into the "magic," let's review the most common mistakes users make when trying to go ​from AI art beginner to master​:

1. Anatomical Errors (The Uncanny Valley): The person looks beautiful, but on closer inspection, they have six fingers or their limbs are awkwardly twisted.
2. Text-to-Image Mismatch: You request a "cyberpunk night view" but get a "bright, cheerful cartoon."
3. Missing Details: You explicitly asked for a "cat wearing sunglasses," but the cat is there, and the sunglasses are missing.
4. Text Generation Gibberish: You want to generate an accurate Slogan within the image, but the result is a stream of unreadable alien symbols.

If you've experienced any of the above, rest assured: it's not the model, it's the lack of specific visual direction in your ​Prompt​. The following sections will teach you the 5 Golden Rules to get Nano Banana 2 to obey your commands and thoroughly ​eliminate "broken" art​.

What is Nano Banana 2?

Before diving into the ​5 Golden Rules​, let's clarify the role of this "protagonist." Nano Banana 2 is Google's latest ​AI Image Generation and Editing Model​.

Compared to Midjourney or other competitors, Nano​​ Banana 2 possesses three core advantages, which are the foundation for generating cinematic quality results:

1. Precise Semantic Understanding (Prompt Adherence): It adheres to details in the prompt with high fidelity, even in complex scenario descriptions.
2. Native Text Rendering: It solves a major problem in the AI art community—it can generate clear, correctly spelled text within the image (e.g., poster titles, logos).
3. Conversational Editing: After generating an image, you can directly instruct it, "change the background to blue" or "add a hat," without needing to regenerate the entire picture.
