UnverifiedCFG guidance strength typically seeks the best balance between 5 and 12; too low deviates from the prompt, while too high produces oversaturation or artifacts.72% similarUnverified负向提示词在Stable Diffusion等开源模型中通过Classifier-Free Guidance（CFG）机制实现，CFG Scale通常设置在7-12之间72% similarUnverifiedClassifier-free guidance (CFG) runs both a conditional branch and an unconditional branch simultaneously, amplifying the conditional signal by subtracting the unconditional direction from the conditional direction, trading a doubling of inference cost for quality improvement.68% similarUnverifiedUsing excessively high CFG values during low-step inference amplifies the correction magnitude at each step, leading to oversaturated colors, distorted contrast, and even artifacts; when using an accelerated LoRA, the CFG value often needs to be reduced from 7.5 to 2–4.66% similar
