Prompting Principles

Tell it what matters.

Good prompts separate the subject, layout and details that need to stay fixed. Start with these three habits.

For text01

Write the words, then design the poster.

Quote the exact headline. Specify placement, hierarchy and the copy to omit. Review every letter before publishing.

For information02

Supply the facts. Define the structure.

Give the model your verified data, labels and step count. Ask for one clear reading order rather than an open-ended diagram.

For people03

Name what stays the same.

Use clear reference images. Describe each person's appearance and position, and explicitly preserve faces, hairstyles and clothing.

FAQ

A few useful answers.

Models, references, credits and the current playground.

What is Nano Banana 2.1?

Nano Banana 2.1 is Google's image generation and editing model, announced on October 6, 2026. It improves text rendering, infographic layouts, prompt adherence and character consistency. Its Gemini API model ID is gemini-nano-banana-2.1.

Which model generates images on this page?

The live RenderPop playground currently runs Nano Banana 2 through Pollo. Nano Banana 2.1 is not connected here yet. The prompt collection is designed for the Nano Banana family, and every example on this page was generated with Nano Banana 2.

Is the online generator free?

Browsing and copying prompts is free. Generating an image requires a RenderPop account and 20 credits. This dedicated playground uses the paid image workflow; the free Fast generator is available separately on RenderPop.

Can I generate 4K images here?

Nano Banana 2.1 supports 1K, 2K and 4K in Google's API. This RenderPop playground currently generates at 1K only. A 4K option is not offered here yet.

How many reference images can I upload?

You can upload up to 14 JPG or PNG reference images, up to 20 MB each. For edits, describe what should change and what should remain the same. For group portraits, give each person a clear role and keep the reference order consistent.

How do I get accurate text on a poster?

Put the exact wording in quotation marks, distinguish the headline from supporting text, and specify placement. Short copy is easier to control. Check spelling, numbers and layout in the generated image before using it.

How does Nano Banana 2.1 compare with Nano Banana Pro?

Nano Banana 2.1 is the efficiency-focused option, with improved typography and multi-turn character consistency. Nano Banana Pro emphasizes complex visual tasks, localization and precise creative control. The comparison on this page describes Google's models; RenderPop's Pro credit workflow is a separate product concept.

What happens if a generation fails?

The playground uses RenderPop's existing credit reservation workflow. Credits reserved for a failed generation are released automatically. Successful images are saved in your RenderPop library.
