## Introduction

<!-- Provide a quick summary of what the model is/does. -->
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:

```python
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](https://github.com/TencentARC/PhotoMaker/README_pmv2.md). 


## Limitations

<!-- This section is meant to convey both technical and sociotechnical 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.

## Citation

<!-- If there is a paper or blog post introducing the model, the APA and Bibtex information for that should go in this section. -->
