It makes the image for a post or an ad from a description. In Batch Banana you say where it will run, and Agent sets the frame: 4:5 for a feed, 9:16 for stories and Reels, 16:9 for a YouTube thumbnail. One image on Nano Banana 2.1 costs 10 credits.
Edits
Each after is an edit made on Nano Banana 2 with the image beside it attached. The candle was made in Batch Banana to stand in for your product. Nano Banana 2.1 has since replaced Nano Banana 2. Drag the divider to compare.
The jar, the label and the flame stay. The kitchen becomes a windowsill in morning light.
Only the line changed. The type, its place, the jar and the light stayed.
What you get
Each one made in its own frame. The dashed lines on the story mark what Meta asks you to keep clear.
One short line in the image
The line changed, the rest kept
The candle images were made for this page; the rest are real runs from the Batch Banana model guides. Every word meant for the image is in quotes, and Image 1 means a reference was attached.
Image 1 is the product: keep the jar, the amber glass, the kraft label and the lit wick exactly. Place it on a folded oatmeal linen throw on a wooden windowsill, soft morning light from the left, a sprig of dried eucalyptus beside it. The upper third is plain cream wall. No text.
Add "Burns for 60 hours." in a small dark serif, centered in the clear wall at the top. Keep everything else in Image 1 unchanged.
Change the line to "Two for $40 this week." Keep the type, its place, the jar and the light of Image 1 unchanged.
Add "New: Cedar and Smoke" in a small dark serif on the plain wall just above the jar, inside the middle band, not on the label. Keep the label blank, the top and bottom of Image 1 plain and everything else unchanged.
Keep the jar, the linen and the light from Image 1. Recompose as a tall frame: the jar in the middle band, the top 14% plain cream wall, the bottom 35% plain linen, nothing near the sides. No text.
Keep the jar, the linen and the light from Image 1. Recompose as a wide frame: the jar in the right third, open cream wall across the left two thirds. No text.
Image 1 is the product: keep the jar exactly. Four of them in a row on a bathroom shelf, steam on the mirror behind, soft daylight, room above for a caption. No text.
A Halvard chocolate bar lying flat along the bottom edge of the frame on deep blue velvet, its cobalt wrapper printed with fine white contour lines and "HALVARD" in a tall cream serif, a square of chocolate showing. Hard light from the left. The rest of the frame is empty blue velvet, room for a headline.
A poster for a club night called "HEAVY". The word is so heavy it has sagged and pooled at the bottom of the sheet like melted glossy black wax, the top of the letters still crisp. Hot pink background. Small text at the top: "Saturdays at Armazém 4".
Change the word to "DENSE". Keep the melted black letters, the pink background, the small text and the layout of image 1 unchanged.
A labelled exploded diagram titled "Inside a Halvard bar": a chocolate bar pulled apart into its layers, with five labels on thin lines: "Paper wrapper", "Copper foil", "Dark chocolate", "Sea salt", "Rye crumb". Flat editorial style on cream.
Only Flux 3 Image blurred the passers-by, as the prompt asked. Max and Pro softened the street behind her instead, and Klein drew the crowd sharp.
Same prompt, every model

Made in Batch Banana for the model guides on October 2, 2026. Nothing is retouched.
How it works
Feed, story, Reel, Short, thumbnail or ad. The placement sets the aspect ratio as a setting, so the prompt spends its words on the picture.
One short line in the image, on a model that sets type well, such as Ideogram 4.5. Longer copy goes in the caption or the ad's text fields.
If you set the headline yourself, describe what fills that empty part of the frame so the model leaves it plain.
Agent loads it before a social post, a story, a thumbnail or an ad.
Agent skill
Sizes posts, stories, thumbnails, and ads for each app. On a 9:16 story it keeps words and logos out of the top 14% and bottom 35%, as Meta asks.
Feed posts · Stories · Thumbnails · Ads
See all skillsInstagram and Facebook feed posts take 4:5 or 1:1. Stories, Reels and Shorts take 9:16. A YouTube thumbnail takes 16:9. Agent sets the ratio for you, so you only say where the image will run.
On 9:16, Meta asks that the top 14%, the bottom 35% and 6% of each side stay free of text and logos. Agent puts the subject and any words in the band between and keeps the top and bottom plain.
Yes, one short line works best, on a model that sets type well such as Ideogram 4.5. Put longer copy in the caption or the ad's text fields, where it stays editable.
Yes. Attach the finished ad and say what changes and what stays. The candle variant above is an edit of the first ad: only the line changed, and the type, the jar and the light stayed.
Yes. Attach the photo, describe the new scene and say what stays: the product, its label, its color. The candle above started as a phone photo on a kitchen counter. Check each result against the real product.
It depends on the model: 10 credits per image on Nano Banana 2.1, 14 on Ideogram 4.5 and 6 on Flux 3 Image. You can start for free.
