277 "# GAN Upscaler Workflow\n\nA fast approach for upscaling videos using GAN models. It can't create new detail like diffusion can, but it's much faster.\n\n- **Model determines output size** — 2x models upscale 2x, 4x models upscale 4x\n- **Tip:** Upscale 4x first, then use a resize node to bring it down to your target resolution\n\n## Model Links\n\n- [Hugging Face:Comfy-Org/Real-ESRGAN_repackaged](https://huggingface.co/Comfy-Org/Real-ESRGAN_repackaged)\n\n**ModelScope mirrors** (alternative repo location)\n\n- [ModelScope:Comfy-Org/Real-ESRGAN_repackaged](https://modelscope.cn/models/Comfy-Org/Real-ESRGAN_repackaged)\n\n**upscale_models**\n\n- [RealESRGAN_x4plus.safetensors](https://huggingface.co/Comfy-Org/Real-ESRGAN_repackaged/resolve/main/RealESRGAN_x4plus.safetensors) (63.8 MB)\n\n## Model Storage Location\n\n```\n📂 ComfyUI/\n├── 📂 models/\n│ ├── 📂 upscale_models/\n│ │ ├── RealESRGAN_x4plus.safetensors\n```\n\n## Report Issue\n\nNote: Please update ComfyUI first ([guide](https://docs.comfy.org/installation/update_comfyui)) and prepare required models.
