Exploring Stability AI: A New Contender in Image Generation
Written on
Chapter 1: Introduction to AI in Image Generation
In recent years, Artificial Intelligence (AI) has gained significant attention, particularly for its capabilities in transforming text into images. While some view AI as a potential threat, many believe it has the power to enhance our daily lives. But what is AI, really?
AI is a branch of computer science dedicated to the creation of machines capable of performing tasks that typically require human intelligence, such as understanding speech, translating languages, processing images, and interpreting natural language. Its applications range from autonomous vehicles to advanced medical diagnostics, indicating a promising future. However, there are legitimate concerns regarding its societal implications, which we won’t delve into today.
A noteworthy advancement in AI technology is the emergence of Stability AI, a model that competes with the well-known Dall-E 2. This innovative tool excels in converting popular textual inputs into high-quality images. Stability AI boasts the ability to generate exceptional images without usage restrictions.
Section 1.1: What is Stability AI?
Stability AI is an advanced model that utilizes a vast database of images to convert text prompts into visual representations. This technology is rooted in latent diffusion models, similar to those employed by Dall-E and Google Imagen. The model was first introduced by Katherine Crowson from the CompVis team.
Stability AI operates on a dataset known as Aesthetics, a subset of the LAION 5B core dataset. This technology enhances image rendering by utilizing stable diffusion ratings integrated with the CLIP model, allowing it to produce 512x512 pixel images within seconds using standard consumer GPUs.

Subsection 1.1.1: How Does the Stability AI Generator Function?
The Stability AI generator allows users to create images from a pool of over 5 billion images, utilizing 800 million parameters. It operates effectively with 10 GB of VRAM, and users can experiment with it for free in a beta version on Discord. However, it is essential that each text prompt is unique, or else the same images will be produced.
To access Stability AI for free, users must join a 'Waitlist' via a designated link. Notifications are typically sent via email within 1–2 weeks for those approved to use the AI. After receiving the invitation to join Discord, users may need to wait several days before they can generate images. A verified Discord account is necessary to proceed.
Once on the server, users can execute commands in the '#dream' chat rooms. Each user can create one command every 60 seconds after the initial waiting period. The commands required for image generation are as follows:
!dream [-h] [--tokenize] [--height HEIGHT] [--width WIDTH]
[--cfg_scale CFG_SCALE] [--number NUMBER] [--separate-images]
[--grid] [--sampler SAMPLER] [--steps STEPS] [--seed SEED]
[--prior PRIOR] [--ascii] [--asciicols ASCIICOLS]
[prompt ...]
Positional Arguments:
- prompt
Optional Arguments:
- -h, --help
- --tokenize, -t (show CLIP tokenization output)
- --height HEIGHT, -H HEIGHT (default is 512; must be a multiple of 64)
- --width WIDTH, -W WIDTH (default is 512; must be a multiple of 64)
- --cfg_scale CFG_SCALE, -C CFG_SCALE (default is 7.0)
- --number NUMBER, -n NUMBER (default is 1)
- --separate-images, -i (return multiple images as separate files)
- --grid, -g (composite multiple images into a grid)
- --sampler SAMPLER, -A SAMPLER (available options include ddim, plms, k_euler, etc.)
- --steps STEPS, -s STEPS (default is 50)
- --seed SEED, -S SEED (random seed)
- --prior PRIOR, -p PRIOR (vector adjust prior)
- --ascii, -a (returns an ASCII representation)
- --asciicols ASCIICOLS, -ac ASCIICOLS (if ASCII, specify number of text columns)
Before diving into the images generated by Stability AI, consider that each image is created using the '!dream' command. Below are examples of images created with this command, alongside comparisons to Dall-E 2 outputs.
The first video compares various AI art generators, including Stability AI, Dall-E 2, and MidJourney, showcasing their unique features.
Here are the prompts used for creating some stunning images:
- Prompt: "the ufo, high saturation, high contrast, vibrant"
- Command: !dream "the ufo, high saturation, high contrast, vibrant" -H 640 -C 20.0 -n 4 -i -s 150 -S 788846748
- Prompt: "Anthropomorphic goose wearing steampunk leather goggles, leather facial mask, a long leather coat, dramatic lighting, full body shot"
- Image 1 (Dall-E 2) vs. Image 1 (Stability AI)
- Prompt: "Iron Man and Howard the Duck, various digital art"
- Image 2 (Dall-E 2) vs. Image 2 (Stability AI)
- Prompt: "35mm photo of Elizabeth from Bioshock Infinite, cosplay, digital art"
- Image 3 (Dall-E 2) vs. Image 3 (Stability AI)
- Prompt: "Elon Musk (1987), horror, game design fanart"
- Image 4 (Stability AI)
- Prompt: "film still of a Squirrel working in a research lab filling test tubes, 8 k"
- Image 5 (Stability AI)
Now, let’s take a look at another insightful video that discusses whether Stability AI truly outperforms Dall-E 2.
