# BRIA-4B-Adapt ControlNet Union Model Card

BRIA-4B-Adapt ControlNet-Union, trained on the foundation of [BRIA-4B-Adapt Text-to-Image](https://huggingface.co/briaai/BRIA-4B-Adapt), supports 6 control modes, including depth (0), canny (1), colorgrid (2), recolor (3), tile (4), pose (5). This model can be jointly used with other ControlNets.

This model combines technological innovation with ethical responsibility and legal security, setting a new standard in the AI industry. Bria AI licenses the foundation model with full legal liability coverage.
