Image generation
Text-to-image, image-to-image and inpainting.
Style locking, subject consistency, upscaling and compliance checks run on one path, so the images that come out are ready for your asset library.
Reproducible image generation at batch scale
Anchor a character or product once and later compositions keep it consistent. A tuned parameter set can be saved as a named style for the whole team. Every generation passes a quality and compliance check, and anything that fails is re-run without using quota.
Built for production
Subject consistency
Anchor a character or product once and keep the same face and packaging across later compositions.
Reproducible styles
Use the built-in presets, or save your own tuned parameter set as a named style.
High-resolution output
Built-in upscaling and detail repainting keep edges clean and text intact.
Automatic checks
Quality, copyright risk and content compliance are checked automatically, and failures are re-run without being billed.
API capabilities
Text-to-image, image-to-image, inpainting
Three modes on one endpoint, with masks specified at pixel or semantic level.
Size and composition control
Any aspect ratio, with pose, line-art and depth-map structural constraints.
Batch jobs
Submit several prompts at once, scheduled concurrently and returned by asynchronous callback.
Negative prompts and fixed seeds
The same seed reproduces an earlier result exactly, which helps A/B tests and debugging.
Clear commercial rights
The commercial scope of each result comes back with the response, with no legal grey area.
Straight to object storage
Results can be written to your bucket and CDN without a round trip.
Product and packaging assets
Shoot a product once and derive the full set of scene shots, colour variants and store-listing sizes.
In-app scene illustrations
Illustrations for rooms, scenes and device cards produced as a set in one style.
Manuals and installation diagrams
Installation steps, button legends and pairing guides drawn to one visual standard.
Localised market assets
Swap setting and people per region for the same selling point while the product itself stays identical.

Register a product or character as an anchor ID and point every later generation at it — series consistency comes for free.
