Nano Banana 2.1 Edit
Natural-language image editing with Google Nano Banana 2.1: edit, restyle or merge 1–14 images while keeping up to 4 characters and 10 objects consistent. To change one part, say what changes and what stays, or circle the region on the image. 1K, 2K and 4K output.
Parameter
| Parameter | Typ | Standard | Bereich oder Optionen |
|---|---|---|---|
aspect ratio aspect_ratioShape of the image. auto keeps the input image's shape when editing and makes a square otherwise. Ultra-wide and ultra-tall shapes (4:1, 1:4, 8:1, 1:8) are supported. | select | auto | auto, 1:1, 3:2, 2:3, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9, 21:9, 4:1, 1:4, 8:1, 1:8 |
resolution resolutionOutput size: 1k ≈ 1 MP, 2k ≈ 4 MP, 4k ≈ 16 MP. 2k costs 1.5× and 4k 2.8× the 1k price. | select | 1k | 1K · ~1 MP (1k), 2K · ~4 MP (2k), 4K · ~16 MP (4k) |
enable image search enable_image_searchUse images found through Google Image Search as visual context. Photos of real people from the search are not used. Adds a small fee per request. | select | false | true, false |
enable web search enable_web_searchGround the image in live Google Search results (current events, weather, charts). Adds a small fee per request. | select | false | true, false |
media resolution media_resolutionHow much detail the model reads from input images and video frames. low leaves room for long videos; high keeps fine detail. Does not change the price. | select | default | default, low, medium, high |
thinking level thinking_levelHow much the model reasons before drawing. high helps with infographics, dense text and multi-character scenes but takes longer; minimal is fastest; default means medium. Does not change the price. | select | default | default, minimal, medium, high |

Regeln der LUVI Prompt Engine für Nano Banana
TARGET MODEL: Nano Banana 2.1 (Google, gemini-nano-banana-2.1). It reads a brief the way a language model reads one: positively, in prose. There is no negative_prompt, no weighting and no style dial.
Regeln, die gelten müssen
- Narrative prose, not tag stacks. Describe a scene a person could photograph or design: register → subject and action → setting → light → camera → in-image text → finish.
- Exclusions become presences that do NOT name the excluded thing: "no people, no cars" → "a quiet, deserted street", never "no cars" and never "empty of people and cars". Naming the unwanted thing can summon it.
- Aspect ratio and resolution are parameters. Never write "16:9", "widescreen", "4K" or "8k" into the prose — on a conflict the parameter wins and the words are wasted.
- In-image text: put every visible string in double quotes, exactly as it must read, and describe the type (weight, style, colour) and its placement in plain words. Never write the words "in quotes" or "quoted" — the model draws the quotation marks. Every other visible surface (signs, apparel, packaging, screens) is either given quoted copy or described as plain/blank; unquoted incidental lettering comes back as gibberish.
- Keep quoted copy verbatim. If it contains an em dash, the model draws it as a separate rule that splits the line: add OUTSIDE the quotes that the text stays on a single line with a literal em dash between the phrases. Example: a sign reading "Taze simit — İçeride çay var" on a single line, with a literal em dash between the two phrases.
- Non-English copy (e.g. Turkish İ ı ğ ş ç) is kept character-exact and LARGE in the frame; small lettering drops diacritics at any resolution.
- People: keep every physical detail the user gave (age, build, hair, wardrobe, expression) — never flatten a described person to "a man"; vague unnamed people drift toward real public-figure lookalikes. Keep distinct on-screen identities few; give extras varied faces or defocus them.
- Never ask for a transparent background — the model has no alpha. Ask for a plain seamless white background instead.
Was am besten funktioniert
- Open with the operation and the deliverable: "Create an image: a photorealistic product photograph of …", "… an infographic poster …".
- State purpose and audience when known ("for an e-commerce product page", "suitable for a 4th grader").
- Many elements → order them in words: "First … Then … Finally …".
- When the user names light, lens or mood, phrase it concretely ("soft window light from the left" beats "cinematic lighting"). Do not add light directions, lenses, camera specs, scene elements (buildings, props, background figures) or wardrobe the user did not ask for — expand only what the user wrote.
- Prose over JSON: when the user supplies JSON, rewrite its content as prose — JSON loses counted details and soft details.
