Generative AI has taken a massive leap during the last couple of years, paving the way for new possibilities. And Stable Diffusion is a one-of-a-kind generative AI that was launched in 2022 and can produce photorealistic images, videos and 3D design animation from text and image prompts. With continuous evolutions, it can create highly precise and beautiful results that can match human creativity. Join ChicMic Studios and let’s understand what Stable Diffusion is, how it works and its underpinning.
Stable Diffusion: The Basics
As mentioned in the introduction, Stable Diffusion is a generative AI model designed to accept text or image prompts and produce photorealistic AI images, videos and 3D design animations. Within the last three years, the model has undergone considerable development to create highly precise images/videos to be used in mainstream projects. The model is the brainchild of researchers and engineers from LMU, RunwayMI, and CompVis who based it on the Latent Diffusion model. It was originally trained on 512×512 images through a subset of the LAION-5B database. Unlike earlier models such as GANs (Generative Adversarial Networks), Stable Diffusion is designed to be both computationally efficient and versatile, making it suitable for various applications.
How does it work?
The brains behind the model used a different approach from other image generation models. The diffusion models use Gaussian noise to encode images and then use a noise predictor along with a reverse diffusion process to redevelop the image.
Stable Diffusion varies from general models as it does not use the pixel space of the image, instead using a reduced-definition latent space. It does so because a color image of 512×512 resolution has 786,432 viable values. On the other hand, Stable Diffusion relies on compressed images that are 48 times smaller at 16,384 values and reduced processing needs. The advantage transfers to the end users who can run it on systems with a GPU and 8GB VRAM.
Diving deeper to understand Diffusion
Diffusion models are generative models that generate new data as close to the data received in training. The concept takes inspiration from the physical process of diffusion, where particles spread out over time. In AI, the model is trained to reverse this process: it starts with random noise and iteratively refined it to reconstruct an image. Stable Diffusions produces images as the data and it works in two main phases.
- Forward Diffusion:
- A perfect image is gradually disfigured by adding noise in continuous steps.
- It helps create a training dataset where the model learns how images degrade or disfigure progressively.
- Reverse Diffusion
- The model is trained to reverse the noise addition process.
- The model takes the noisy image and progressively predicts and removes noise to generate a clear, high-quality image.
Large Datasets for Training
The researchers fed stable diffusion vast datasets that contained millions of images and their corresponding descriptions. It underwent extensive training that enabled the model to understand complex relationships between text and visuals. Thus, it allowed Stable DIffusion to create highly detailed and contextually accurate images.
Why Stable Diffusion stands out?
Stable Diffusion has managed to create waves worldwide through its accuracy, accessibility and ease of use. Anyone can download it from the internet and run on consumer-grade graphics cards. They can effectively input prompts and create highly photorealistic AI images. Let’s understand the reasons in details:
Text-to-Image Synthesis
It is clear so far that Stable Diffusion can generate images from textual prompts. Users can input a description, and the model produces a visual representation that aligns closely with the given text.
