## 🧠 FlashVSR (ComfyUI Integration Model)

This repository hosts the **FlashVSR model weights** used in the [ComfyUI-FlashVSR](https://github.com/1038lab/ComfyUI-FlashVSR) project.
It provides fast and efficient **video super-resolution** powered by **FlashAttention-based architectures**.

### 📦 Model Overview

**FlashVSR** (Flash Video Super-Resolution) is a high-performance video SR model that leverages efficient attention computation to upscale low-resolution videos while maintaining temporal consistency.

This version is provided for **ComfyUI integration**, optimized for direct use with the [ComfyUI-FlashVSR extension](https://github.com/1038lab/ComfyUI-FlashVSR).

### ⚙️ Usage (with ComfyUI)

1. **Install** [ComfyUI](https://github.com/comfyanonymous/ComfyUI)
2. **Clone** the FlashVSR node extension:

   ```bash
   git clone https://github.com/1038lab/ComfyUI-FlashVSR.git
   ```
3. **Download the model files** from this Hugging Face repo:

   * Place them inside:

     ```
     ComfyUI/models/FlashVSR/
     ```
4. **Launch ComfyUI** and load the FlashVSR workflow.
