FLUX.1 [dev] is a general-purpose text-to-image model from Black Forest Labs, balancing image quality against speed and cost. Give it a text prompt and it produces detailed images, with optional controls for the number of outputs, aspect ratio, guidance strength and inference steps.

It is served through Hormouz behind an asynchronous predictions API. You submit a prediction, then poll until the image is ready.

Generation is billed at a flat $0.025 per image. Hormouz provides stable access to FLUX.1 [dev] from inside Iran, with no foreign credit card or circumvention tooling required.
