What the AI image generator does
The AI image generator is a tool inside Keter Labs, an AI creative studio. You pick a model, write a prompt and get one to four images in the shape you need. This AI image creator charges 2 credits per image, 8 for a default run of four.
Pick a model
Switch to Nano Banana Pro to use it as a Nano Banana Pro AI image generator, or pick FLUX for a seed.
| Model | Reference images | Seed |
|---|---|---|
| GPT Image 2 | Yes | No |
| Nano Banana Pro | Yes | No |
| Nano Banana 2 | Yes | No |
| FLUX.1 [dev] | No uploads, saved styles as text | Yes |
| FLUX.1 [schnell] | No uploads, saved styles as text | Yes |
| Auto | Chooses for you | Varies |
Pick the aspect ratio for where the image goes
The shape decides where the subject sits. 1:1 is the default.
| Ratio | Fits | Framing tip |
|---|---|---|
| 1:1 | Feed post, profile picture, product tile | Subject in the centre |
| 4:3 | Blog image, slide | Some room at the edges |
| 16:9 | YouTube thumbnail, web banner | Subject on one side, space for a title |
| 9:16 | Story, Reel, phone wallpaper | Top and bottom kept clear |
Prompt examples by use
Good AI image prompts name the subject, setting, style and light. Ask for no text and add the words later in Designer.
| Use | Example prompt | Ratio |
|---|---|---|
| Realistic product photo | Matte black water bottle on a light oak table, soft window light | 1:1 |
| Poster | Retro travel poster of a coastal town at sunset, empty sky at the top, no text | 9:16 |
| YouTube thumbnail or banner | Surprised person holding a cracked phone, rim light, plain blue right half, no text | 16:9 |
| Instagram post | Overhead latte and croissant on a marble counter, warm natural light | 1:1 |
| Phone wallpaper | Misty pine forest at dawn, muted greens, tall trees filling the frame | 9:16 |
| Pixel-art scene | Pixel-art fishing village at night, glowing windows, 16-bit game style | 4:3 |
Use a reference image
GPT Image 2 and both Nano Banana models take PNG, JPEG or WebP references up to 8 MB. Upload it as a Style to match a look, or as a Character to keep a person or mascot. Saved styles from your library work too.
| To change an existing photo itself, use Reimagine. |
