180+ Best Stable Diffusion Negative Prompts with Examples
Updated on
Stable Diffusion is an AI model that has been making waves in the AI-generated art industry. Negative prompt is one of the methods to improve the quality of these generated images. Using negative prompts can be useful when you want to filter out unwanted content from the generated images.
This article presents more than 180 best Stable Diffusion negative prompts along with examples. If you are an artist, a developer, or just interested in how AI art works, this guide will be helpful for you.
What Is a Negative Prompt Stable Diffusion
Stable Diffusion is a process where AI models generate images based on textual descriptions. A Stable Diffusion prompt is a textual input to guide an AI model in generating specific images. Negative prompts are used to direct the AI on what should not be present in the generated content. In other words, a negative prompt can be used to filter out undesirable content produced by the AI system, such as images with specific objects or patterns.
For instance, if you are generating an image of a serene landscape but want to exclude any buildings, you would use a negative prompt such as "no buildings." This directs the AI to focus on natural elements like trees, mountains, and rivers, thereby enhancing the overall quality and relevance of the image.
Universal Negative Prompt Stable Diffusion
When working with Stable Diffusion, it's beneficial to have a set of universal negative prompts that can be applied across various projects to maintain image quality and relevance. These universal prompts help eliminate common unwanted elements, ensuring that the generated images meet the desired standards consistently. Here are some genetic instructions you can write in your negative prompts when using Stable Diffusion.

Stable Diffusion Negative Prompt NSFW
When using AI to generate images, especially in professional or public settings, it's crucial to ensure that the content is appropriate and safe for all audiences. This is where NSFW (Not Safe For Work) negative prompts come into play. These prompts help filter out inappropriate or explicit content, ensuring that the generated images adhere to acceptable standards. So, the following are some Stable Diffusion NSFW negative prompts.
nsfw, nude, nudity, uncensored, explicit content, cleavage, nipples
Stable Diffusion Negative Prompt Weight
Stable Diffusion allows users to adjust the model's attention or the importance of each prompt. Prompt weight plays a crucial role in controlling the influence of specific instructions on the final image. You can use parentheses () to increase the model's attention to enclosed words, and square brackets [] decrease it. Here's a demonstration of how it can continuously adjust the overall weight of the negative prompt.
Cheat sheet:
- a (word) - Increase attention to "word" by a factor of 1.1.
- a ((word)) - Increase attention to "word" by a factor of 1.21 (= 1.1 * 1.1).
- a (word:1.5) - Increase attention to "word" by a factor of 1.5.
- a (word:0.25) - Decrease attention to "word" by a factor of 4 (= 1 / 0.25).
- a [word] - Decrease attention to "word" by a factor of 1.1.
- [word | word] - Blend multiple prompts; add: number to decrease weight.
- (word | word) - Blend multiple prompts; add: number to increase weight.
- word AND word - Blend multiple prompts using AND; weights can be used.
- [word:to:word] - Blend "word" and "word" equally.
- [word:word:step] - Switch to the second part of the prompt ("word") after a specified number of steps (e.g., dog:mecha:20 means after 20 steps stop drawing dog and start drawing "mecha").
- [word:word:percentage] - Switch to the second part of the prompt after a specified percentage of steps (e.g., dog:mecha:0.2 means switch to "mecha" after 20% of steps).
If you want to use any of the literal ()[] characters in the prompt, use the backslash to escape them: anime_\(character\).
