A list of negative prompts for anime images in Stable Diffusion

Anime images generated by AI have become increasingly popular, thanks to new deep learning models like Stable Diffusion. These models can create stunning anime art from text prompts provided by the user.

However, getting high-quality anime images requires carefully crafting your prompts and steering the AI away from generating unwanted content. Negative prompts are essential for this.

In this article, I share prompt engineering tips and plenty of negative prompt examples you can use to create better anime images with Stable Diffusion.

What Are Negative Prompts

Negative prompts are a way to tell the AI model what you don’t want to see in the generated image. They work just like regular prompts, except instead of describing what you want the AI to create, negative prompts describe what kinds of things should be avoided.

For example, adding “low resolution, jpeg artifacts, watermark” as a negative prompt tells Stable Diffusion not to create low-quality or watermarked images.

Why Negative Prompts Are Important

  • Steer the AI away from biased training data
  • Prevent distorted faces, limbs, or other anatomical mistakes
  • Stop the AI from mixing anime with realism or 3D renders
  • Avoid unwanted abstract patterns or shapes
  • Ensure high image quality without artifacts

Useful Negative Prompts For Anime

Here are some commonly used negative prompts that help Stable Diffusion generate better anime images:

Basic Image Quality

low quality, normal quality, jpeg artifacts, JPEG artefacts, low resolution, lowres, bad anatomy, bad proportions, missing limbs, distorted limbs, extra limbs, fused limbs, mutation, deformed, worst quality, disfigured, mangled face, corrupted, glitchy, extra fingers, missing fingers, fewer digits, cropped, worst face

Prevent Abstract Patterns or Shapes

abstract, geometrical background, psychedelic background, kaleidoscope, fractal, intricate pattern

Avoid Unwanted Styles

3D, CGI, clay, cartoon, pixar, sculpture, toy, rendered, hyperrealistic, photorealistic, still life, real life, movie, film

Stop Sexualization

nude, porn, hentai, ecchi, lewd, underwear, bikini, lingerie, sexy, fetish

Example Prompts

Here are some full prompts using negative prompts to create anime art with Stable Diffusion:

Anime Girl Portrait

A beautiful anime girl with long pink hair, purple eyes, wearing a black dress with white lace and ribbons. Soft lighting, delicate features, gentle smile, highly detailed, digital painting.

Negative prompt: low quality, normal quality, jpeg artifacts, JPEG artefacts, low resolution, lowres, bad anatomy, bad proportions, missing limbs, distorted limbs, extra limbs, fused limbs, mutation, deformed, worst quality, disfigured, mangled face, corrupted, glitchy, extra fingers, missing fingers, fewer digits, cropped, worst face, 3D, CGI, clay, cartoon, pixar, sculpture, toy, rendered, hyperrealistic, photorealistic, still life, real life, movie, film, nude, porn, hentai, ecchi, lewd, underwear, bikini, lingerie, sexy, fetish

Anime Character Full Body

A tall, strong anime man with dark skin, white hair, and red eyes, wearing futuristic silver armor with glowing blue trim and an energy sword. Dramatic dynamic pose, extremely detailed intricate armor, cinematic lighting, digital painting by Artgerm and Rossdraws.

Negative prompt: low quality, normal quality, jpeg artifacts, JPEG artefacts, low resolution, lowres, bad anatomy, bad proportions, missing limbs, distorted limbs, extra limbs, fused limbs, mutation, deformed, worst quality, disfigured, mangled face, corrupted, glitchy, extra fingers, missing fingers, fewer digits, cropped, worst face, abstract, geometrical background, psychedelic background, kaleidoscope, fractal, intricate pattern, 3D, CGI, clay, cartoon, pixar, sculpture, toy, rendered, hyperrealistic, photorealistic, still life, real life, movie, film, nude, porn, hentai, ecchi, lewd, underwear, bikini, lingerie, sexy, fetish

Anime Landscape

A lush green forest with a shimmering lake, pink cherry blossom trees, and a small shrine, misty mountains in the distance, vibrant sunset colors fill the sky, highly detailed dramatic lighting, fantasy landscape, trending on artstation HQ.

Negative prompt: low quality, normal quality, jpeg artifacts, JPEG artefacts, low resolution, lowres, bad anatomy, bad proportions, missing limbs, distorted limbs, extra limbs, fused limbs, mutation, deformed, worst quality, disfigured, mangled face, corrupted, glitchy, extra fingers, missing fingers, fewer digits, cropped, worst face, 3D, CGI, clay, cartoon, pixar, sculpture, toy, rendered, hyperrealistic, photorealistic, still life, real life, movie, film, nude, porn, hentai, ecchi, lewd, underwear, bikini, lingerie, sexy, fetish

Advanced Negative Prompt Techniques

In addition to adding negative prompt text, there are some other advanced techniques you can use to further improve anime images generated by Stable Diffusion:

Textual Inversion

This involves training an AI model to recognize unwanted images, then using that model to generate negative prompts tailored to your needs.

Classifier Guidance

You can use a classifier to guide the AI to generate more anime-like images. Classifiers identify how “anime” an image looks, allowing the AI to optimize images to match the anime style better.

Checkpoint Modifications

Editing the actual weights and architecture of Stable Diffusion checkpoints to specialize them for anime generation. This technique requires expert knowledge.

Conclusion

Crafting the perfect prompts is key to getting Stable Diffusion to generate stunning anime art. Make sure to use negative prompts to steer the AI away from unwanted content and styles.

As you can see from the examples above, negative prompts help prevent distorted faces, abstract patterns, 3D rendering, and more.

Keep experimenting with prompts and negative prompts to find the right balance for your needs. Over time, you will be able to create amazing AI-generated anime images consistently.
