What is Stable Diffusion?

Stable Diffusion is a deep learning model that utilizes a technique called diffusion processes to generate images from textual descriptions. To put it simply, when you give Stable Diffusion a prompt (such as "a beautiful sunset") the model is trained to generate a realistic image of something that matches your description.

The diffusion process involves adding noise to the input image and then gradually reducing the noise over time to produce a final image. This process results in images that are more detailed and realistic than traditional deep-learning models.

Stable Diffusion is a significant improvement over previous text-to-image models because it can handle complex and abstract textual descriptions. It does this by utilizing a new approach called stable training, which enables the model to generate high-quality images that are consistent with the textual input.

How is Stable Diffusion Used?

Stable Diffusion has a wide range of applications, including e-commerce, advertising, and video games. For example, e-commerce websites can use Stable Diffusion to generate images of products based on textual descriptions, enabling them to showcase products that may not have real-life photos available.

Ad agencies can use Stable Diffusion to create unique and eye-catching visuals for their campaigns. Similarly, game developers can use the model to generate game assets like characters and environments from textual descriptions.

Stability AI, the revolutionary company behind Stable Diffusion, has released this model under a permissive license. Users have access to generate images for any purpose – commercial or non-commercial – thanks to Stability AI's policy on commercial use. You can use Stable Diffusion with confidence and create stunning visuals whenever you need them!

Getting Started with Stable Diffusion

Stable Diffusion can be run in different ways, depending on your needs and resources. The two most common ways to run Stable Diffusion are through cloud-based services or locally on your machine.

Using Stable Diffusion Locally

Running Stable Diffusion locally requires installing and configuring the necessary libraries and dependencies. When used locally, beginners can greatly benefit from installing a GUI (Graphing User Interface) that simplifies the configuration process and makes it easier to manage and run experiments.

The minimum recommended VRAM (Video Random Access Memory) for running the model locally is 4GB, which may be too slow for some users. If you do have access to a machine with over 4GB of VRAM, then it is likely a better option to run Stable Diffusion locally. This way, you will save on costs and have more control over your image generations.

When you run Stable Diffusion on your local computer, installing new models, extensions, hypernetworks and training your own models becomes a breeze.

One disadvantage you'll run into with a minimum setup is speed. While a device with 4GB or less VRAM can run Stable Diffusion, even small generations can take up to several minutes. If you're in a hurry for your results and don't have the hardware to spare, then cloud services are likely your best bet.

Using Stable Diffusion in the Cloud

Cloud-based services offer a convenient way to run Stable Diffusion without requiring any significant hardware investment. Similar to running the model locally, you have many options to choose from when going the cloud route. Services like Google Colab, Runpod, and RunDiffusion provide users with an interactive environment for running experiments and generating images.

Cloud services allow you to take advantage of powerful hardware, such as the latest NVIDIA Tesla GPUs, NVIDIA 3090s, and AMD Ryzen Threadripper. With this type of hardware, you can expect to generate images with Stable Diffusion at much faster speeds than running it locally.

However, cloud services come with their own set of costs and limitations. For example, most cloud providers don't have a way to upload your custom Stable Diffusion models and other advanced models such as custom LoRa and VAE. If your generations heavily rely on your fine-tuned models, some cloud providers may not have the support you need.

Using Stable Diffusion Online

Websites like Clipdrop, HappyAccidents, and Leonardo.ai provide users with an easy-to-use platform for generating images based on text input. To make image generation accessible to everyone, some online services offer "Run Now" functions for a variety of models.

These platforms can be useful for those who don't have the time or resources necessary to learn and configure Stable Diffusion by themselves. However, the results of these online services won't be as good as running them locally or in the cloud. Online services often use obsolescent models and provide limited options for customization, if any.

Most online services offer free credits, or a limited amount of free generations before requiring a subscription or credit purchase. This makes it easy to hop in and generate AI images without having to spend any money upfront.

Local, Online, or Cloud? How to Decide

Whichever option you choose, it is important to remember that the better your hardware, the faster the model will run and the more detailed your results will be. You should also consider the limitations and terms of cloud providers, as they can vary greatly.

The easiest way to decide whether you should run Stable Diffusion locally or in the cloud is simply by looking at your hardware. The minimum recommended VRAM (Video Random Access Memory) for running the model locally is 4GB, which may be too slow for some users.

In conclusion, if you're looking for a quick and easy way to start using Stable Diffusion, cloud services may be the right choice for you. But if you're willing to invest in hardware, running Stable Diffusion locally is always an option that offers more power and control over your image generations.
