Qwen image-edit nodes aim to preserve input resolution and cut VRAM use

Fine-Run992 · reddit · 2026-07-22

A Reddit thread digs into memory offloading and resolution handling in a Qwen image-edit pipeline on ComfyUI.

• The author compares a custom pipeline against the stock ComfyUI setup on limited VRAM hardware.
• They report that the stock QwenImageEditPlusPipeline appears to collapse outputs to about 1 MP, even when the input is much larger.
• The custom nodes claim to preserve input resolution up to a configurable cap, aligned to 32 px.
• The implementation also calls the FlowMatchEulerDiscreteScheduler pipeline directly so the sigma/timestep/conditioning behavior matches training more closely.
• The post argues this is a true CFG implementation with separate conditional and unconditional passes.
