Have you ever wondered how artificial intelligence can create realistic and original images from text descriptions? If so, you might be interested in the new image generation model by Stability AI, a leading research lab that focuses on generative AI and human infrastructure.
This model offers several advantages over previous models, such as higher quality, faster speed, lower cost, and easier customization. We will explain how Stable Cascade works, what it can do, and how you can try it out for yourself. You can learn more about it from this article.
What is Stable Cascade?
Stable Cascade is a new feature in Stability AI, a research lab that focuses on generative AI and human infrastructure. It is a text-to-image model that can generate realistic and original images from text descriptions. It compresses images in three steps to a tiny space, making it better and more adaptable.
It’s achieving remarkable outputs while utilizing a highly compressed latent space. Stable Cascade is available on GitHub for researchers but not commercial use. It is being released under a non-commercial license that permits non-commercial use only.
Features of Stable Cascade
- Text-to-image: Create images from text descriptions, such as “a dragon”.
- Image-to-image: Transform images from one style or domain to another, such as sketch to photo.
- Inpainting: Inpainting can be used for creative purposes, such as generating new designs, or for practical purposes, such as restoring damaged photos.
- Outpainting: Fill in or extend parts of an image, such as a hole or a background.
- Canny Edge: Generate images from edge maps, such as a car from its outline.
- 2x Super Resolution: Enhance the quality of low-resolution images, such as a bird or a document.
Models of Stable Cascade
To use Stable Cascade, you need to have the following components:
- Stage A: A pretrained diffusion model that can generate 1024×1024 images from 24×24 latents.
- Stage B: A pretrained model that can encode 1024×1024 images to 24×24 latents and decode them back to images.
- Stage C: A text-to-latent model that can generate 24×24 latents from text prompts.
You can download the pretrained models for Stage A and B from the Stability GitHub page. For Stage C, you can either use the provided 1B or 3.6B parameter models or train your own model using the scripts and configs in the same repository.
Comparison
- Stable Cascade is based on the Würstchen architecture, which combines competitive performance with unprecedented cost-effectiveness for large-scale text-to-image diffusion models,
- It can generate images with 16x less cost than a similar-sized Stable Diffusion model, thanks to its modular design that decouples the text-conditional generation from the decoding to the high-resolution pixel space.
- Stable Cascade can also generate images two times faster than the standard basic Stable Diffusion XL model. It doesn’t compare to the speed of SDXL Turbo, though.
- It can produce image variations by extracting embeddings and adding noise to existing images, as well as fine-tune the model with ControlNet and LoRA techniques.
- Stable Cascade is released under a non-commercial license that permits non-commercial use only, while Stable Diffusion is open-source and can be used for any purpose.
- It is currently in research preview and not yet available for public use, while Stable Diffusion can be downloaded and run offline on consumer hardware.
Frequently Asked Questions
How Does Stable Cascade Work?
Stable Cascade uses a three-stage approach to generate images. First, it converts the text input into a small 24×24 image. Then, it enlarges the image to a higher resolution. Finally, it adds details and colors to the image.
How Can I Use Stable Cascade?
It is currently in research preview and not yet available for public use. However, you can download and run Stable Diffusion, which is open-source and can be used for any purpose.
Who Developed Stable Cascade?
Stable Cascade was developed by Stability AI, a company that also created Stable Diffusion, another AI image generator model.
Conclusion
Stable Cascade is a breakthrough in AI image generation, as it introduces a new three-stage architecture that can produce realistic and diverse images from text prompts. It also offers major advantages in terms of efficiency, flexibility, and customization, as it can be trained and fine-tuned on consumer hardware with minimal cost and time.
Stable Cascade sets a new standard for text-to-image diffusion models and opens up new possibilities for creative and practical applications. Stability AI invites users to experiment with it and share their feedback and suggestions. They also plan to release more updates and extensions for the model in the future.
