Description
I train a qwen image lora, however, sometimes when the CFG is set to 4, it tends to produce results of relatively low quality. Reducing the CFG value can improve image quality, but the adherence to the instructions will decrease.

Research direction
No files, entry points, or tests are identified in the report. First reproduce Qwen image LoRA generation at CFG 4 and at lower CFG values, then trace the relevant training and inference paths; done means identifying the cause of the quality regression and validating a fix against both image quality and instruction adherence.
