BRIA 2.3 ControlNet GenFill Model Card

Trained exclusively on the largest multi-source commercial-grade licensed dataset, BRIA 2.3 ControlNet GenFill guarantees best quality while safe for commercial use. The model provides full legal liability coverage for copyright and privacy infringement and harmful content mitigation, as our dataset does not represent copyrighted materials, such as fictional characters, logos or trademarks, public figures, harmful content or privacy infringing content.

BRIA 2.3 ControlNet GenFill is a model designed to fill masked regions in images based on user-provided textual prompts, specialised in the tasks object replacement, addition, and modification within an image.

What's New

BRIA 2.3 ControlNet GenFill should be applied on top of BRIA 2.3 Text-to-Image and therefore enable to use Fast-LORA . This results in an extremely fast inpainting model, requires only 6.3s using A10 GPU.
