Image generation

Real-ESRGAN is a widely used image super-resolution model. It enlarges an image while restoring detail and reducing artefacts, turning small or soft pictures into sharper, higher-resolution ones.

It is served through Hormouz behind an asynchronous predictions API. Submit a prediction with your image, then poll until the upscaled result is ready. The required input is image; optional controls include scale, the upscale factor (default 4), and face_enhance, which cleans up faces (default off).

Pricing is a flat $0.005 per run, making it a very cheap way to upscale at scale. Hormouz provides stable access to Real-ESRGAN from inside Iran, with no foreign credit card or circumvention tooling required.
