Fast image generation
A low-cost route for multilingual commercial visuals and rapid iteration.
Generate polished photography, architecture, food, nature, and commercial visuals with custom sizing and prompt upsampling controls.
The Playground and API use the same model ID: flux-1.1-pro. This endpoint accepts text prompts only; reference-image editing uses the separate Image-to-Image route.
Explore reference limits, sizes, formats and quality settings for FLUX 1.1 Pro.
Final cost depends on the output tier and input add-ons. Check the live page price and task record for the final charge.
Choose the destination and aspect ratio before composing subject, scene, material, light, and text.

No. This route is text-to-image only.
The page exposes Custom width / height and Custom, 1:1, 16:9, 9:16; use the Playground contract for the final available set.
Billing is per successful generated image. Resolution or quality differences, when present, are reflected by the live page price.
POST an asynchronous task to /v1/tasks with model set to flux-1.1-pro and put generation fields inside input.
Start with the subject, environment, and visual goal, then add material, light, camera, and exact text.

Generate in Custom width / height across 4 supported aspect ratios.
Confirm the result in Playground, then reuse the same prompt and model ID in an asynchronous task.
