Introduction

Prompt-Free Diffusion is a diffusion model that relys on only visual inputs to generate new images, handled by Semantic Context Encoder (SeeCoder) by substituting the commonly used CLIP-based text encoder. SeeCoder is reusable to most public T2I models as well as adaptive layers like ControlNet, LoRA, T2I-Adapter, etc. Just drop in and play!

Setup

conda create -n prompt-free-diffusion python=3.10
conda activate prompt-free-diffusion
pip install torch==2.0.0+cu117 torchvision==0.15.1 --extra-index-url https://download.pytorch.org/whl/cu117
pip install -r requirements.txt

Demo

We provide a WebUI empowered by Gradio. Start the WebUI with the following command:

python app.py

All models can be downloaded at HuggingFace link.

Tools

We also provide tools to convert pretrained models from sdwebui and diffuser library to this codebase, please modify the following files:

└── tools
    ├── get_controlnet.py
    └── model_conversion.pth

You are expected to do some customized coding to make it work (i.e. changing hardcoded input output file paths)
