Stable Diffusion - Prompts 提示词工程框架_vr

当前 stable diffusion 模型使用基础的 stable-diffusion-v1-5，即 v1-5-pruned-emaonly.safetensors。

stable diffusion 的正向提示词是一种用来描述想要生成的图像的语言，可以通过不同的词语、符号、权重和相关性来控制生成图像的内容、风格和质量。正向提示词可以根据不同的场景和需求进行灵活的选择和组合，以达到理想的效果。

正向提示词结合反向提示词，输出的效果较好。反向提示词，如下：

nsfw,(worst quality:2),(low quality:2),(normal quality:2),lowres,normal quality,((monochrome)),((grayscale)),skin spots,acnes,skin blemishes,age spot,(ugly:1.331),(duplicate:1.331),(morbid:1.21),(mutilated:1.21),(tranny:1.331),mutated hands,(poorly drawn hands:1.5),blurry,(bad anatomy:1.21),(bad proportions:1.331),extra limbs,(disfigured:1.331),(missing arms:1.331),(extra legs:1.331),(fused fingers:1.61051),(too many dingers:1.61051),(unclear eyes:1.331),lowers,bad hands,missing fingers,extra digit,bad hands,missing fingers,(((extra arms and legs)))
