It achieves high-quality few-step generation while providing stable improvements as more sampling steps are added. - 🔀 **Multiple Architectures**: **AnyFlow** supports any-step distillation for both **causal** and **bidirectional** video diffusion models. - 🎬 **Multiple Tasks**: **AnyFlow** supports Text-to-Video, Image-to-Video, and Video-to-Video generation within one causal video diffusion model. - 📈 **Scalable Performance**: **AnyFlow** is validated from **1.3B** up to **14B** parameters. This directory contains **AnyFlow-Wan2.1-T2V-1.3B-Diffusers** (a 1.3B bidirectional video diffusion model) in Hugging Face Diffusers format, derived from the [**Wan2.1-T2V-1.3B-Diffusers**](https://huggingface.co/Wan-AI/Wan2.1-T2V-1.3B-Diffusers) text-to-video backbone. ## Video Demos <div align="center"> <video width="80%" autoplay loop muted playsinline controls> <source src="https://nvlabs.github.io/AnyFlow/assets/videos/demo_video.mp4" type="video/mp4"> Your browser does not support the video tag. </video> </div> ## 🔥 Latest News!! * May 4, 2026: 👋 We've released the codebase and weights of AnyFlow. ## Quickstart ### Setup Environment **1️⃣ Create Conda Environment** ```bash conda create -n far python=3.10 conda activate far ``` **2️⃣ Install PyTorch and Dependencies** ```bash pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu128 pip install -r requirements.txt --no-build-isolation ``` ### Model Downl...
