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.

The model is based on SD3 finetuning; therefore, the license follows the original SD3 license.
