PhotoMaker V2

PhotoMaker V2 Model Card

Introduction

Users can input one or a few face photos, along with a text prompt, to receive a customized photo or painting within seconds (no training required!). Additionally, this model can be adapted to any base model based on SDXL or used in conjunction with other LoRA modules.

Model Details

It mainly contains two parts corresponding to two keys in loaded state dict:

1. id_encoder includes finetuned OpenCLIP-ViT-H-14 and a few fuse layers.

2. lora_weights applies to all attention layers in the UNet, and the rank is set to 64.

Usage

You can directly download the model in this repository. You also can download the model in python script:

from huggingface_hub import hf_hub_download
photomaker_ckpt = hf_hub_download(repo_id="TencentARC/PhotoMaker-V2", filename="photomaker-v2.bin", repo_type="model")

Then, please follow the instructions in our GitHub repository.

Limitations

• The model's customization performance degrades on Asian male faces.
• The model still struggles with accurately rendering human hands.

Bias

While the capabilities of image generation models are impressive, they can also reinforce or exacerbate social biases.
