How to write AI image prompts for a job
Start with the job, then describe the picture. Google's prompting tips for Nano Banana Pro cover subject, composition, action, location, style, camera and lighting, plus any text that should appear. A job adds the frame and the empty space, so every prompt here follows one order:
- Job and frame: "a 4:5 social ad", "a 16:9 thumbnail".
- Subject: concrete nouns, such as "a sweating glass bottle", not "an amazing product".
- Layout: where the subject sits and which part of the frame stays empty.
- Light and palette: direction, softness and two or three colours.
- Words: the exact text in quotes, with a type style.
The quotes rule comes from Google's Nano Banana prompting guide, which also says to describe what you want rather than what you don't. Length is rarely the limit: Playcut's image tool accepts up to 8,000 characters, and no prompt here comes close.
Which model each prompt is tagged for
Each group carries a "Run on" chip, and a card that needs a different model has its own. Words in the picture go to Nano Banana Pro, drafts and text-free scenes to Nano Banana 2, odd frames to Grok Imagine Image.
| Model | Tagged for | Credits | Watch for |
|---|---|---|---|
| Nano Banana Pro | Anything with words: headlines, thumbnails, labels, diagrams | 67 at 1K or 2K, 84 at 4K | Slower; its thinking step is always on |
| Nano Banana 2 | Drafts and scenes without text | 20 at 512, 34 at 1K or 2K, 43 at 4K | No multi-region edit |
| Grok Imagine Image | Odd ratios and the auto frame | 10 from text, 20 with a reference | 2K at most, 2 references, studio only |
Grok Imagine Image is the cheapest text-to-image model we run and has the longest ratio list of the three, including 2:1, 20:9 and auto, but it is not the one for clean lettering.
Ad creative
Ads carry a headline and need room for a button, so most of these run on Nano Banana Pro, the model we run for lettering.
-
Static ad with a headline
4:5A 4:5 social ad for a yuzu soda: a sweating glass bottle on a sunlit concrete ledge, deep shadows, an orange and cream palette, the headline "Slow Mornings, Bright Starts" in bold condensed sans-serif at the top, and clear space at the bottom for a button. -
Before-and-after split
1:1A 1:1 ad split down the middle: on the left, tangled charging cables on a desk in cool, flat light; on the right, the same desk tidy with one white charging stand in warm light. "Before" and "After" in small white capitals above each half. -
Offer badge
4:5A 4:5 ad for a city bike-share: a teal bike leaning on a canal railing at sunrise, soft backlight, a round coral badge reading "FIRST RIDE HALF PRICE" in the top right corner, and open sky above for copy. -
Lifestyle ad, copy added later

Four matching carousel cards
Nano Banana 2 2x2 gridA 2x2 grid of four matching ad cards for a meal-kit brand, each showing one plated dish from above on the same sage green linen, with the same window light and framing, and space at the top of each card for copy.
Thumbnails and cover images
A thumbnail is judged at a fraction of its size, so these ask for one subject, hard contrast and no more than three words, each in quotes.
-
Reaction thumbnail
16:9A 16:9 video thumbnail: a person on the right third with a surprised face, looking at a huge glowing yellow "WAIT?" on the left, a dark blue background with a soft vignette, strong rim light, high contrast. -
Tutorial thumbnail
16:9A 16:9 thumbnail for a baking tutorial: a sourdough loaf being sliced on a wooden board, steam rising, warm side light, a hand-drawn white arrow pointing at the crumb, and "PERFECT CRUMB" in chunky white letters on the left. -
Podcast episode cover
1:1A 1:1 podcast cover: two vintage microphones facing each other on a mustard yellow background, flat graphic style with paper texture, "Side Quest" in large black rounded type and "Episode 42" smaller below. -
Travel vlog thumbnail
Nano Banana 2 No textA 16:9 travel thumbnail: a turquoise lagoon seen from a cliff edge, a small figure in a red jacket on the right for scale, saturated but natural colour, bright midday light, the left 40% kept simple for a title. -
Online course cover
16:9A 16:9 course cover in flat illustration style: a laptop, a notebook and a coffee cup on a desk seen from above, a navy, coral and off-white palette, and "Spreadsheets in 7 Days" in bold geometric sans-serif.
Social formats: stories, carousels and banners
Placement decides the frame, so each prompt states its ratio. The banner uses a ratio only Grok Imagine Image offers among our models.
Packaging and labels with real words
These are label concepts drawn from scratch, every word in quotes. Google warns that small text and spelling may not render perfectly, so proofread each letter before print.
-
Honey jar label
A squat glass jar of honey on a plain cream background, soft studio light, a hexagon-shaped paper label reading "Wildflower Honey" in warm brown serif with "Raw · 340 g" in small type beneath, crisp and legible. -

Carton and its flat layout
A folded cosmetics carton beside its unfolded flat layout on a pale grey desk, printed with "Calm Night Balm" in thin lowercase sans-serif, a lavender and grey palette, side panels showing neat blocks of small type.Treat those small blocks as layout, not final text; small body copy is the part most likely to come out garbled.
Infographics and diagrams
Diagrams live or die on their labels. Google says to always verify the factual accuracy of data-driven visuals, so check every number and label yourself.

From copied card to finished image in Playcut
Copy a card, open the image studio and paste it; nothing arrives pre-filled from this page. Then:
- Pick the model on the chip. The picker shows the credit cost, and switching to Grok Imagine Image moves a 4K setting down to 2K for you.
- Set the ratio the prompt names. Unsure what a placement needs? Find your aspect ratio first.
- Ask for a grid to see options. A 2, 2x2, 3x3 or 4x4 grid bills as one image.
- Add references when a logo or face must match: up to 14 on the Nano Banana models, read in upload order, and 2 on Grok Imagine Image.
Every plan includes a commercial licence, and both Nano Banana models render up to 4K. For scenes built from one uploaded photo, see the Playcut AI image generator.
