Learn what a negative prompt is in Stable Diffusion and how to use it to generate high-quality images!

Stable Diffusion is a deep learning, text-to-image model released in 2022.

It is primarily used to generate detailed images conditioned on text descriptions, though it can also be applied to other tasks such as inpainting, outpainting, and generating image-to-image translations guided by a text prompt.

To use Stable Diffusion and generate art or images as per your desire, you must know some parameters, one of which is a Negative Prompt.

In this guide, you will learn what a negative prompt is in Stable Diffusion and how to use it to generate high-quality images per your defined prompt parameters.

Also, do not forget to check our post on the best stable diffusion anime prompts and try some artwork with it.

Let’s get started!

What is a Negative Prompt In Stable Diffusion

A negative prompt is a way to use Stable Diffusion in a way that allows the user to specify what he doesn’t want to see, without any extra input. It is a parameter that tells the Stable Diffusion model what not to include in the generated image.

Negative prompting influences the generation process by acting as a high-dimension anchor, which the process strays away from. It can also improve the image output by specifying abstract concepts such as “blurry” and “pixelated”.

Negative prompting affects the generation process by acting as a high-dimensional anchor from which the process moves away. This lets the output image be more precisely controlled. Users can use negative prompts to make unique images with more detail and accuracy.

For example, you might have generated a portrait, but sometimes Stable Diffusion provides duplicates, even though you offer it with parameters like ‘Don’t add duplicates’. That’s because it understands negative prompts better than human language.

In that case, what you can do instead of regenerating the same prompt is provide a negative prompt like ‘duplicate’ or ‘poorly Rendered face.’

Here’s what you will get without a negative prompt:

Here’s what you will get by adding a negative prompt such as “Duplicate”:

How to Use Negative Prompts In Stable Diffusion or Dream Studio

Though you might have an idea about using negative prompts in Stable Diffusion, let’s understand this with more examples, and by the end, you will be provided an entire list of negative prompts for stable diffusion that you can use to remove particular objects or enhance your images.

As per the documentation of stability.ai, trying out negative prompts is as simple as putting “| negative prompt>: -1.0” to the prompt in DreamStudio or Stable Diffusion.

An example would be to add “| deformed, ugly: The error “-1.0, too many fingers:-1.0” is sometimes a workaround for the problem of producing an excessive number of fingers.

Now, let’s understand Negative Prompts with another example.

Example #1: Let’s say we generate a hybrid between a German Shephard and a Tiger with this given prompt – a hybrid between a German Shephard:0.7 and a tiger, photography, award-winning, documentary, wildlife, 8k

Prompt: “a hybrid between a German Shephard:0.7 and a tiger, photography, award winning, documentary, wildlife, 8k”

We provided stable diffusion as a negative prompt.

In response to the following prompt, Stable Diffusion prioritizes German Shephard. You should thus anticipate a visual that demonstrates the priority of a German Shepherd over a Tiger.

In this scenario, Stable Diffusion prioritizes the German Shepherd and then applies the difference (0.3) to the Tiger without user input.

Example #2: Here’s another example, which you can see below.

The first image has bushes and trees surrounding the german architecture generated through a basic prompt.

But the other image shows what will be generated if you add a negative prompt to lower the dominance of Trees near the area.

Note

The negative prompts seed and CFG scale are not available as separate options in Dream Studio. In contrast, the negative prompt syntax described above can be used in Dream Studio.

However, Stability Diffusion’s specific negative prompt panel can use the following parameters. By the way, using negative prompts in Stable Diffusion v2.0 is highly recommended.

    • blurry
    • cloned face
    • cropped
    • deformed
    • dehydrated
    • disfigured
    • duplicate

    Also: Your current list contains two ‘out of frame’ prompts (which would have been caught with an alphabetic ordering)

    Request: Provide a list of negative prompts for use with appropriate image genres, such as human (faces, bodies); scenery; imaginative; etc.

    Nice work, guys!

  • ugg no example of protocol around multiple neg propts do I place comma just a space or what between multiple of neg prompts

    • So sorry for that, will edit it. For your information, use comma between multiple negative prompts.

  • Hello, quick question. Is there a way to add a default negative prompt so I don’t have to type it in when starting stable diffusion? and thank you for the article it is very informative.

    • Haven’t found anything like default negative prompt, however try to copy this and paste it in your negative prompt section. This will work and save it for future use too: out of frame, lowres, text, error, cropped, worst quality, low quality, jpeg artifacts, ugly, duplicate, morbid, mutilated, out of frame, extra fingers, mutated hands, poorly drawn hands, poorly drawn face, mutation, deformed, blurry, dehydrated, bad anatomy, bad proportions, extra limbs, cloned face, disfigured, gross proportions, malformed limbs, missing arms, missing legs, extra arms, extra legs, fused fingers, too many fingers, long neck, username, watermark, signature,
