通用基础负面提示词能拦截80%常见图像崩坏，含lowres、blurry、bad anatomy等67项，直接填入Negative Prompt框即可；人物类需叠加专用模板，风格化图像须匹配排除项，嵌入式文件如badhandv4可强化手部纠错。
通用基础负面提示词模板

生成任何图像前，先塞进这组保底词，能拦住80%的常见崩坏——低分辨率、模糊、畸形手、多余手指、文字水印全被压住。复制粘贴这串：lowres, blurry, worst quality, low quality, normal quality, jpeg artifacts, signature, watermark, username, artist name, text, error, cropped, out of frame, extra digit, fewer digits, bad anatomy, bad hands, missing fingers, extra fingers, deformed hands, mutated hands, poorly drawn hands, fused fingers, too many fingers, long neck, malformed limbs, extra limbs, missing arms, extra arms, bad legs, extra legs, bad feet, extra feets
这串词没有权重标记，直接填进Negative Prompt框即可生效。它不挑模型版本，SD v1.5、SDXL 1.0甚至部分Flux微调模型都认得。但【不要在SDXL模型上硬套v1.5专用词如bad anatomy】，否则可能反向激发解剖错误。
人物类图像专用负面模板
画人像、全身角色图时，光靠通用词不够——AI对人脸、手指、躯干比例的“自由发挥”特别顽固，必须加针对性压制。
方法一：精简高效版（适合快速出图）
nsfw, paintings, cartoon, anime, sketches, ugly, deformed face, disfigured, bad eyes, cross-eyed, poorly drawn face, extra head, fused body, missing body, bad proportions, twins, amputation, bad tongue, strange fingers, missing hands, extra hands, connected hand, bad hands, wrong fingers, 4 fingers, 3 fingers, deformed hands, extra legs, bad legs, many legs, more than two legs, bad feet, wrong feet, extra feets
方法二：高精度强化版（适合商业级人像/角色设计）
(worst quality:2), (low quality:2), (normal quality:2), monochrome, grayscale, skin spots, skin blemishes, age spot, glans, disabled, distorted, bad anatomy, morbid, malformation, amputation, bad proportions, twins, missing body, fused body, extra head, poorly drawn face, bad eyes, deformed eye, unclear eyes, cross-eyed, long neck, malformed limbs, extra limbs, extra arms, missing arms, bad tongue, strange fingers, mutated hands, missing hands, poorly drawn hands, extra hands, fused hands, connected hand, bad hands, wrong fingers, missing fingers, extra fingers, 4 fingers, 3 fingers, deformed hands, extra legs, bad legs, many legs, more than two legs, bad feet, wrong feet, extra feets
注意：高精度版里所有带括号+冒号的项（如(worst quality:2)）都带权重，数值越大压制越强。但【权重总和不宜超过10】，否则会过度抑制导致画面僵硬、失去细节层次。
风格化图像避坑负面词
当你明确要某种风格——比如赛博朋克、水墨风、胶片感——负面词就得配合切换，否则AI会偷偷混入违和元素。
第一步：识别你正向提示词里的风格关键词
例如你写了“cyberpunk city, neon lights, rain-soaked street”，那就要防AI塞进写实摄影感或水彩笔触。
第二步：匹配对应风格的排除项
→ 写实/摄影风：加上paintings, cartoon, anime, sketches, illustration, drawing, comic, manga, 3d render
→ 动漫/二次元风：加上photorealistic, realistic, photograph, DSLR, ultra-detailed, film grain
→ 水墨/国风：加上oil painting, acrylic, digital art, vector, 3d model, photorealistic, sharp focus
→ 赛博/科幻风：加上pastel colors, soft lighting, watercolor, vintage photo, old film
第三步：保留质量底线词
不管什么风格，lowres, blurry, jpeg artifacts, text, watermark 这五项必须保留，它们是跨风格通用的质量锚点。
这一步做完，风格就稳了。不用反复试错，AI不会在霓虹高楼里突然画出毛笔飞白。
嵌入式负面词（Embedding）加载法
有些问题单靠文本词压不住，比如手部结构错误——这时要用训练好的embedding文件，相当于给AI装一个“手部纠错插件”。
方法一：下载并放置文件
去Civitai搜关键词“badhandv4”或“negative_hand-neg”，下载.safetensors格式文件 → 放进WebUI根目录下的embeddings文件夹。
方法二：在Negative Prompt中调用
直接输入：badhandv4 或 negative_hand-neg（不带扩展名，大小写敏感）
方法三：组合使用效果更稳
badhandv4, (deformed hands:1.3), (extra fingers:1.2), (missing fingers:1.1)
注意：embedding不是万能的。如果用了badhandv4后人物手掌变透明或消失，说明该embedding与当前模型不兼容，立刻删掉它，退回纯文本方案。
按错误类型反查负面词
图已经崩了？别重跑，先看哪出问题，再精准补刀。
手指异常 → 补：extra fingers, missing fingers, 4 fingers, 3 fingers, fused fingers, too many fingers, deformed hands, poorly drawn hands
脸部扭曲 → 补：poorly drawn face, disfigured, bad eyes, cross-eyed, deformed eye, unclear eyes, extra head, long neck
背景杂乱 → 补：out of frame, cropped, duplicate, text, signature, watermark, jpeg artifacts, blurry background
画面模糊 → 补：blurry, lowres, worst quality, low quality, normal quality, jpeg artifacts, soft focus
出现文字 → 补：text, error, username, artist name, signature, watermark, logo
这组词是“问题-对策”映射表，看到什么错就加什么，不用全塞。加多了反而让AI困惑，生成速度变慢，细节丢失。
