FLUX 2 [max] - AI Model API and Pricing

Fourteen tools, one engine: where to start

For a new picture from a prompt, open AI Image Generator. Start from Product on marble, Food shot or Cinematic portrait. To change a photo you already have, AI Photo Editor covers Change sky, Brighten face and Make it night. AI Image Editor handles Product on white, Swap the object and Remove logo.

Expand Image adds room with More on the sides, More above and below or More all around. Image to Image restyles an upload with presets like Night version or Photoreal from art. Several specialist tools run on the same model. These include AI Pet Portrait, AI Haircut, AI House Exterior Design, AI Tattoo Generator and Line Art Generator.

Prompts that play to its realism

It responds well to camera and light language. For a product shot, try "ceramic coffee mug on a walnut desk. Morning window light from the left, shallow depth of field, 50mm photo." For a believable street portrait, try "woman in a gray wool coat on a rainy street at dusk. Neon reflections on wet pavement, candid."

Describe materials and the light source before style words. Realism comes from the surface details you name.

Framing: pick the ratio before you write

Four aspect ratios are offered: 1:1, 4:5, 16:9 and 9:16. Use 4:5 for an Instagram feed post and 9:16 for Stories and Reels covers. Pick 16:9 for a website hero or a YouTube thumbnail. Choosing the ratio first changes the composition the model builds, which beats cropping a square afterwards.

Text in the image is the weak point

Lettering is weaker than in GPT Image 2. Short words on a sign may come out fine. A menu, a price list or a poster headline often has mangled letters. Instead, leave space with the Add text space preset and set the type in your design tool. You can also send the layout to GPT Image 2 at 14 credits, which keeps small text readable.

If you only need a quick draft from a prompt, Nano Banana at 12 credits is cheaper. It does not take an upload on Ugesi. When a final image has to go to print, the AI Image Upscaler enlarges it 4x today. Topaz Image Upscale at 13 credits is listed but not open yet.

What it costs per image and per batch

Each image is 16 credits, about $0.17 on the best pack. A batch of ten separate runs is 160 credits, around $1.70. That puts it 36th from the cheapest of 41 image models. It pays to draft on something lighter and switch to this one once the prompt is settled.
