Nano Banana 2.1 Settings Explained
Resolution
Start at 1K for drafts. Choose 2K or 4K for a final image with more detail; higher resolutions cost more credits.
Reference images
Upload up to 14 images. Google describes high-fidelity support for up to 10 object references and 4 character references; 14 images does not mean 14 distinct characters.
Web and Image Search
Web Search helps with current information. Image Search adds visual context and also enables Web Search. Search results do not guarantee factual accuracy.

Nano Banana 2.1 Prompt Examples
Product campaign
Use the uploaded bottle as the exact product reference. Keep its shape, cap, colors and label. Place it on a pale stone plinth with soft morning light and a clean cream background. Leave the left third empty for advertising copy.
Typography poster
Design a portrait poster for a weekend plant market. Headline exactly: "GROW TOGETHER". Subtitle exactly: "Saturday · 10 AM–4 PM". Cream paper background, forest-green typography, botanical illustrations, clear hierarchy and generous margins. No additional words.
Consistent characters
Use the first two references for the two characters. Preserve their faces, hairstyles and clothing colors. Show them browsing a small bookshop together, warm window light, medium-wide composition. Do not add other people.
Wide website banner
An 8:1 panoramic illustration of a peaceful coastal town at sunrise, pastel buildings, calm sea, continuous natural perspective. Keep the center visually quiet for a website headline. No text, repeated buildings or tiled patterns.
Nano Banana 2.1 Test Results
Testing in progress
Every model runs the same eight-category prompt set — portrait, product, poster text, anime character, interior, multi-reference, image editing and character consistency — recording generation time, success rate, text accuracy and identity retention. That run has not finished for Nano Banana 2.1, so this page shows no scores. We do not publish numbers we have not measured.
Nano Banana 2.1 Limitations
- Small text, long passages and factual labels still need a human review.
- Reference consistency and local edits are not guaranteed; inspect areas you asked to preserve.
- The minimum output size is 1K; there is no 512px option.
- This generator does not offer a seed or adjustable Thinking level.
- Follow-up edits use uploaded references rather than a persistent conversation.
