BRIA 2.3 ControlNet Inpainting Fast

Trained exclusively on the largest multi-source commercial-grade licensed dataset, BRIA 2.3 inpainting guarantees best quality while safe for commercial use. The model provides full legal liability coverage for copyright and privacy infrigement 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 is an inpainting model designed to fill masked regions in images based on user-provided textual prompts. The model can be applied in different scenarios, including object removal, replacement, addition, and modification within an image, while also possessing the capability to expand the image.

What's New

BRIA 2.3 ControlNet Inpainting can be applied on top of BRIA 2.3 Text-to-Image and therefore enable to use Fast-LORA . This results in extremely fast inpainting model, requires only 1.6s using A10 GPU.
