放大与修复
Upscale & Restore · 各家还叫它:放大 / 超分 / 高清修复 / Upscaling / Super-resolution
谁能做
还没有模型有明确的官方依据
拿什么跑官方工作流优先;社区仓库标星标,星标是它有没有人真在用的唯一硬指标
- 官方ComfyUI · 放大教程 →Unlike traditional interpolation methods, AI upscaling models (like ESRGAN) can intelligently reconstruct details while maintaining image quality
- 社区ComfyUI Ultimate SD Upscale →ssitu/ComfyUI_UltimateSDUpscale:ComfyUI nodes for the Ultimate Stable Diffusion Upscale script(★1,535,GPL-3.0)
自己部署权重公开的,拿去自己 GPU 上跑

已知限制
· 放大是猜出来的细节,不是把原来看不见的东西找回来 —— 用作证据材料不合适· 人脸要单独走人脸修复模型,通用放大器会把脸放大成蜡像· CodeFormer 是非商用许可,接单前要换成 GFPGAN 或 Real-ESRGAN典型用例
