# ViPer: Visual Personalization of Generative Models via Individual Preference Learning

*Tuning-free framework for personalized image generation*

[`Website`](https://viper.epfl.ch) | [`GitHub`](https://github.com/EPFL-VILAB/ViPer) | [`BibTeX`](#citation)  


We introduce **ViPer**, a method that personalizes the output of generative models to align with different users’ visual preferences for the same prompt. This is done via a one-time capture of the user’s general preferences and conditioning the generative model on them without the need for engineering detailed prompts.


## Installation
For install instructions, please see https://github.com/EPFL-VILAB/ViPer.


## Usage

This model can be loaded from Hugging Face Hub as follows:

```python
from transformers import AutoModelForVision2Seq
from peft import PeftModel

model = AutoModelForVision2Seq.from_pretrained("HuggingFaceM4/idefics2-8b")
model = PeftModel.from_pretrained(model, "EPFL-VILAB/VPE-ViPer")
```

Please see https://github.com/EPFL-VILAB/ViPer for more detailed instructions.

For more examples and interactive demos, please see our [`website`](https://viper.epfl.ch/) and [`Hugging Face Space`](https://huggingface.co/spaces/EPFL-VILAB/ViPer).
