Stable Diffusion is a flexible deep learning, text-to-image model developed by Stability AI. It is based on diffusion technology (released in 2022) that can transform textual descriptions into visual representations. The model utilizes a CLIP ViT-L/14 text encoder to generate high-quality images in response to prompts.
Compared to earlier diffusion models, the latest Stable Diffusion 3.5 significantly reduces memory requirements. It is designed with a great architectural innovation by implementing the diffusion process in a latent space. Earlier models operate directly in image space.
Thanks to the technical breakthrough and its open-source nature, Stable Diffusion has soon attracted a much broader user base, including developers, researchers, individual creators, and enterprise users.
• Constantly Improving with the Version Updates. Since its initial release, this text-to-image generation model has undergone significant evolution. Main versions include Stable Diffusion 1.5, 2.0, 2.1, 3.0, and the latest 3.5 series. They have made substantial improvements in various aspects, including output quality, prompt understanding, and generation capabilities, among others.
• Multiple Model Versions. Several specialized models are designed to address different user needs. The latest base model is Stable Diffusion 3.5. It offers significant improvements over previous versions. There are currently four main versions in the Stable Diffusion family: Stable Diffusion 3.5 Large, Large Turbo, Medium, and Flash.
• Advanced Prompt Understanding. The current Stable Diffusion 3.5 features a sophisticated multi-text encoder architecture that enables it to process more complex and detailed prompts more effectively. It can process test descriptions up to 10,000 characters long. This enables users to provide more detailed descriptions. Meanwhile, Stable Diffusion can produce higher-quality, more accurate results.
• Commercial and Creative Flexibility. Stable Diffusion 3.5 models are released under the Stability AI Community License and Enterprise License. That permits both commercial and non-commercial use. For most casual users, such as researchers, developers, and small businesses with annual revenues of less than $1M, they can use Stable Diffusion freely without restrictions. Users can freely adapt the AI to their specific needs and artistic styles.
As mentioned above, Stable Diffusion’s versatility makes it suitable for almost all users. Both developers, researchers, designers, digital artists, AI hobbyists, and even students can get significant benefits from its capabilities.
The latest Stable Diffusion 3.5 model has advanced capabilities to generate finer image details. Generated photos often have accurate lighting and subjects. Moreover, it can better fit the specific art style based on your prompts.
For most image generation models, areas like human hands and facial features can be particularly challenging. With the adoption of a 16-channel VAE, these common artifacts and imperfections can be effectively addressed. Stable Diffusion is good at rendering accurate lighting effects.
Despite these improvements, Stable Diffusion still has its weaknesses. The model continues to face certain challenges, particularly in full-body renders. Like other AI image generation models, Stable Diffusion often produces unexpected results, particularly when generating complete human figures. The current Stable Diffusion 3.5 performs well with close-up shots, portraits, and various non-human subjects.
The efficiency of Stable Diffusion varies depending on the specific model version used, hardware, output settings, and prompts. Generally, with a powerful NVIDIA GPU, you can easily generate a standard 1024x1024 image in 5-15 seconds. Better than many alternatives, Stable Diffusion allows users to train and fine-tune models on their own datasets. This is particularly valuable for professional users.
Compared to the previous models, the current Stable Diffusion 3.5 is much easier to use. However, the “easy” is highly relative to your technical skills, experience level, and chosen interface.
Multiple approaches are available for different technical comfort levels. Navigate to the official Stability AI website, get a license, and then submit a POST request as required.
Relatively speaking, thanks to various integrated solutions, the setup process of Stable Diffusion has been dramatically simplified. Moreover, Stable Diffusion has a WebUI that carries a comprehensive dashboard for better controlling the generation process. For an effective local deployment, it is also recommended to verify the suggested hardware requirements. For beginners, we recommend using Stable Diffusion on Windows 10 or 11.
Most active communities and platforms, such as Reddit, Discord, and forums, collect related techniques, creations, and problem-solving solutions about Stable Diffusion.
