SD3 Controlnet Inpainting

Finetuned controlnet inpainting model based on sd3-medium, the inpainting model offers several advantages:

Leveraging the SD3 16-channel VAE and high-resolution generation capability at 1024, the model effectively preserves the integrity of non-inpainting regions, including text.
It is capable of generating text through inpainting.
It demonstrates superior aesthetic performance in portrait generation.

Training Detail

The model was trained on 12M laion2B and internal source images for 20k steps at resolution 1024x1024.

Mixed precision : FP16
Learning rate : 1e-4
Batch size : 192
Timestep sampling mode : 'logit_normal'
Loss : Flow Matching

Limitation

Due to the fact that only 1024*1024 pixel resolution was used during the training phase, the inference performs best at this size, with other sizes yielding suboptimal results. We will initiate multi-resolution training in the future, and at that time, we will open-source the new weights.
