Negative prompts for Stable Diffusion
Stable Diffusion's weighted syntax — (term:1.2) for emphasis, (term:0.8) to reduce — gives fine-grained control over generation. Our generator produces a positive prompt with quality tags and a separate negative prompt targeting artifacts likely to appear given your image's content and style.
Copy the positive prompt into your prompt field and the negative prompt into the negative prompt field in AUTOMATIC1111, ComfyUI, or InvokeAI.
FAQ
Why do Stable Diffusion prompts need a negative prompt?
Unlike Midjourney or DALL-E 3, Stable Diffusion relies on negative prompts to suppress common artifacts — bad anatomy, blurry output, watermarks, extra fingers, and low quality. A dedicated negative block dramatically improves results.
What syntax does the negative prompt use?
Weighted token syntax: (worst quality:1.4), (bad anatomy:1.3), blurry, watermark — plus content-specific negatives identified from your image. Compatible with SD 1.5, SDXL, and SD 3.5 in AUTOMATIC1111 and ComfyUI.
Is it free?
Yes. Guests get 3 free generations per day. The output includes both positive and negative prompt blocks, clearly separated for copy-paste.
