图生图高清放大

图生图高清放大：基于 SD 1.5 搭建的高清放大方案，节点规模 12 个、连线 13 条。工作流主路径为 CLIPTextEncode ×2、UpscaleModelLoader ×1、UltimateSDUpscale ×1，配合 输出图像；节点已按执行顺序排布，便于二次修改。主模型 4x-UltraSharp.pth、SD1.5vaeFtMse840000Ema_v10.safetensors、SD1.5majicmixRealistic_v7.safetensors。下载后直接导入即可使用，建议显存 4GB 起。

• 主模型：4x-UltraSharp.pth、SD1.5vaeFtMse840000Ema_v10.safetensors、SD1.5majicmixRealistic_v7.safetensors
• 核心节点：CLIPTextEncode ×2、UpscaleModelLoader ×1、UltimateSDUpscale ×1
• 输出形式：输出图像
• 规模：12 节点 / 13 连线
• 建议显存：4GB 起
• 适用场景：2K/4K/8K 无损放大、细节重绘与纹理修复，救回模糊与 AI 感素材。
