How Does Stable Diffusion Work?

Stable diffusion is a technique that is used to generate AI images. It is a relatively new innovation that is used to create images that look realistic. It is a popular method that has made it possible for AI images to reach new heights.

So, if you want to learn more about how stable diffusion works and what AI tools you can use to learn more about this type of art, this is the perfect article for you. Here, we will discuss everything that there is to know about stable diffusion and AI.

What Is Stable Diffusion?

So, what exactly is stable diffusion? This is a new technology that was developed in 2022. It is known as a generative artificial intelligence (generative AI) model, and it converts the texts into photorealistic images. It creates not only pictures but also videos and animations.

Stable diffusion produces highly detailed images from just a text prompt; even simple requests like asking for a picture of a sunflower can result in a very vibrant and unique image. It can create images of various sizes from 64×64 to 1024×1024 pixels, but optimal results are achieved with its default size of 512×512.

The type of image depends on the prompt that you enter, and the prompt can get more and more unique depending on how many details you add. You can ask the AI tool to create various things, such as paintings, images, cards, videos, and animations. And these can be used for entertainment, advertising, marketing, and much more.

How Does It Work?

Now, the way that the diffusion model works is a little complicated but very fun as well. This is a new model, so of course, it can be perfected more and will be perfected with time.

The model works with diffusion technology and uses latent space. The type of diffusion model it uses is called the latent diffusion model and was made by researchers and engineers from CompVis, LMU, and RunwayML. Stable diffusion can understand pre-trained language models like CLIP. You can train your own model to use the diffusion model, but it obviously requires more effort.

In short, diffusion models can create realistic images of varying resolutions. A diffusion model does that in two steps: the first step is to add noise to a dataset progressively, and then the next step is to learn how to reverse this process. These generate new data based on the data that they are fed. So, the diffusion model creates new images from the ones that already exist. Thus, the result is a highly unique image that is found nowhere else.

How to Build Amazing Images With Stable Diffusion

Now, you know what a stable diffusion model is and how it works as well. The next step is to learn how to use it and how to generate the best-quality images with it. It is super easy to use when you find the right AI tool. Of course, now, many different AI tools use stable diffusion, and some are better than others. Therefore, it is important to find the AI tool that provides you with the best images.

How to Use Stable Diffusion

If you want to use stable diffusion to get amazing images, you need to know how to properly use it. So here are the steps that you should be following in order to get your desired result or even better! This process requires two simple steps.

Step 1

Go to the AI tool and type your prompt; the more detailed it is, the better the result will be. You can write with a lot of words, but there is a word limit. Press enter.

Step 2

Now, you just look at the result generated by the AI. Usually, you will get four images, and you get to click on each to look at it properly. Right-click on the image to save it. If you do not like the image, you can simply click on “generate image” again, and you will get four new images.

Sometimes, there are some AI tools that allow you to add a negative prompt, which shows the things you do not want in the final image. Regardless, the main thing is to add a proper prompt and change it until you get the picture that you are happy with.

How to Generate Amazing Images Using Stable Diffusion

Now, you know the basic steps required to use stable diffusion, but how do you make the prompt better so that you get exactly what you want? This is something that requires a bit more practice and tactics, and with time, you will get better at it.

How to Find the Proper Prompt

If you want to find the proper prompt or want to look at how people get the perfect prompt, there is a website that can help you with it.

Lexica is the AI tool. Basically, you go to the website and select the image you like. After that, you click on it, and you can find the prompt used to generate this image on stable diffusion. You can copy the prompt and paste it into the AI image generator. It is important to note that since the seed of the image will not be the same, the image that will be generated will not be exactly like the one you see on Lexica but rather very similar to it.

Speaking of seeds, what is a seed? Seed is the most important part of stable diffusion, and each image generated by stable diffusion has a different seed. If you want to improve the image that you have already generated, it is important to copy the seed number, save it, and then change the prompt. Now, in some AI tools, you do not need to do this, but in most cases, it is important to remember the seed of the image.

Regardless, if you are a beginner and do not know how to word a prompt, Lexica can help with that. You can also look at different prompts until you understand how to word the prompt properly. However, we will help you with that section as well.

How to Word a Prompt

When you write a prompt, some parts of it are more important than others, but how do you explain that to the AI? You do that by wording the prompt properly, and we will teach you exactly how you can do that.

First of all, it is very important that you start writing the prompt with the most important part of the prompt. For example, if you want a picture of the moon, the first word should be a moon in your prompt. Similarly, the next word should also be important until the last word, which is the least important.

The AI will focus on the word that comes first, and slowly, the words get less and less important. This is why the wording is important.

Not only that, there is another way to make the AI understand the importance of some words, and that is by using parenthesis around the words with importance. You can use two to three parentheses (((moon))), so these words will have more importance in the AI. Both of these methods are important to make the AI see what should come first.

Moreover, for the aesthetic of the picture, such as wanting a dark image, you should use words like “dark,” “gloomy,” “moody,” and “darkness” to describe the image. You can use these words at the end of the prompt or at the beginning. However, another thing to note is that you can use as many of these words as possible. In fact, the more synonyms you use, the better the result will be. The AI will remember to focus on that part of the aesthetic more.

By using these techniques to write a prompt, we are sure you can get outstanding results. Even if you do not get it right the first time, you will eventually understand how it works. However, it is important to note that different AI have different sensitivity to prompt ideas. It depends on the CFG scale of the AI tool. The lower the CFG of the AI, the less likely it is to listen to your prompt, and vice versa. So, choosing a good AI with a high CFG scale is essential to generating images that resemble your vision the most.
