Stable Diffusion Negative Prompt for Nsfw

Prompt /

Negative prompts are an important tool in Stable Diffusion to steer the image generation away from unwanted elements. They give the user more control over the output by specifying terms and concepts that should not appear in the generated image.

Using appropriate negative prompts is especially critical when generating potentially sensitive content, as we will explore here related to NSFW images.

Why Use Negative Prompts for NSFW Content

Stable Diffusion has the potential to generate sexualized or pornographic content, which may be undesired. Negative prompts allow the user to reduce the likelihood of NSFW output without limiting creative possibilities.

Some key reasons to use negative prompts for NSFW content:

  • Avoid legal or ethical issues – Generating and sharing pornographic content of real people could violate laws or ethical codes in some contexts. Negative prompts help avoid this.
  • Focus creativity – Even if NSFW output is acceptable, negative prompts let you steer away from it to focus creativity on other aspects.
  • Improve image quality – NSFW images risk having flaws like bad anatomy. Negative prompts help correct this.
  • Personal comfort – Users may simply feel uncomfortable with or uninterested in NSFW output. Negative prompts give control over this.

Effective Negative Prompts to Avoid NSFW Content

Here are some negative prompt terms and concepts that can help reduce NSFW content in Stable Diffusion:

  • pornographic
  • NSFW
  • lewd
  • underwear
  • bikini
  • swimsuit
  • lingerie
  • topless
  • breasts
  • genitals
  • sex

You can combine these with other prompts about improving image quality:

  • ugly
  • bad anatomy
  • disfigured

Other Tips for Negative Prompts

Here are some other tips when using negative prompts with Stable Diffusion:

  • List terms from most to least important based on prompt weightings
  • Avoid overusing negative prompts as too many can limit creativity or lead to dull images
  • Pair them with descriptive positive prompts to guide the image generation
  • Iteratively tweak and test to find the right balance for your needs

Be purposeful in composing negative prompt lists, evaluate the impact, and refine over time.

Example Prompt Formatting in Stable Diffusion

In addition to using good negative prompt terms, structuring them appropriately in your overall prompt is critical.

Here is an example prompt with proper formatting:

A beautiful fairy with long blonde hair, elegant wings, and a glowing magical wand, wearing an intricate green dress while casting a spell over a mystical forest landscape, digital art, trending on artstation HQ, highly detailed, sharp focus, illustration by Artgerm and Greg Rutkowski and Alphonse Mucha, ((negative prompt)): -1.5

Key elements:

  • Descriptive positive prompt establishing the desired image content and style
  • Specific artists to inform the aesthetic
  • Image quality details like “HQ” and “highly detailed”
  • Double parenthesis around the negative prompts
  • Prompt weight set to -1.5 for strongest exclusion

This structures prompts in a way that clearly directs Stable Diffusion while avoiding unwanted elements.

Experiment with prompt structure in addition to negative prompt terms for best results. Evaluate what formats work well to consistently get high quality, safe-for-work outputs tailored to your creative goals.
