Quick How to! Use Stable Diffusion 3 in 3 minutes | Tutorial | ComfyUI | Colab | Stability AI API
TLDRThis tutorial demonstrates how to utilize Stable Diffusion 3 in just 3 minutes with ComfyUI and Colab, leveraging the Stability AI API. Start by obtaining an API key from the Stability AI website, then use a Google Colab notebook to set up and run the necessary steps. The guide also covers manual installation via terminal for ComfyUI, including configuring the API key and generating images with various settings. The video emphasizes the need for experimentation and credits to achieve desired results.
Takeaways
- 🔑 Start by obtaining an API key from the Stability AI website if you don't already have one.
- 📚 Use a free Google Colab notebook to work with Stable Diffusion 3, as linked in the description.
- 🔍 In the Colab notebook, add a new secret named 'SD3_API' and paste your API key to allow access.
- 🛠 Install all dependencies by running the first step in the notebook.
- 🖼️ Access your Stable Diffusion 3 generator by running step 2 and clicking the provided link.
- 🎨 Update your prompts, select aspect ratio, seed, model style, and hit submit to generate images using the Stability API.
- 💰 You start with 25 credits, which can generate three to six images depending on the model used.
- 🚀 The Turbo model is cheaper, but the full model performs better with text descriptions.
- 🛠️ For Comfy UI, install custom nodes or clone the GitHub repository manually if it's not available in the manager.
- 🔄 Restart Comfy UI and refresh the browser to access the Stable Diffusion 3 node.
- 🌐 Input your prompts, adjust settings like aspect ratio, model, seed, and denoise strength for image generation.
- 📝 Note that while the full model offers better results, it may require several tweaks and credits to achieve the desired image.
Q & A
What is the first step to use Stable Diffusion 3 as described in the tutorial?
-The first step is to obtain an API key from the Stability AI website by logging in or creating an account if you don't already have one.
How do you use a Google Colab notebook for Stable Diffusion 3?
-You open the provided Colab notebook link in the description, make a copy of it, and open the secrets tab to add a new secret named 'SD3_API' where you paste your API key and allow notebook access.
What does running step 1 in the Colab notebook do?
-Running step 1 installs all the necessary dependencies for the Stable Diffusion 3 generator in the notebook.
How do you access your Stable Diffusion 3 generator after running step 2 in the Colab notebook?
-After running step 2, you scroll to the bottom and click on the provided link, which takes you to your Stable Diffusion 3 generator.
What can you do with the Stable Diffusion 3 generator interface?
-You can update your prompts, select aspect ratio, seed, model style, and submit to generate images using the Stability API.
How many credits do you start with when using the Stability API for image generation?
-You start with 25 credits, which allows you to generate three to six images depending on the model used.
What is the difference between the Turbo and the full model in terms of cost and text handling?
-The Turbo model is cheaper, but the full model handles text better and produces better results with text prompts.
How can you install Stable Diffusion 3 in Comfy UI if it's not available in the manager?
-You manually install it by opening the terminal, changing the directory to your custom nodes folder, cloning the GitHub repository, and pasting your Stability AI API key in the configuration file.
What happens after you install Stable Diffusion 3 manually in Comfy UI?
-You need to restart Comfy UI and refresh your browser to see the Stable Diffusion 3 node, where you can then input your prompts and settings.
What settings can you adjust in the Stable Diffusion 3 node in Comfy UI?
-You can adjust the aspect ratio, model, fix the seed, and set the denoise strength for the image.
What is the process for creating a new sign from text to image in the Stable Diffusion 3 node in Comfy UI?
-You input your text prompts, select the settings for aspect ratio, model, seed, and denoise strength, and then run the process to generate the image.
Outlines
🛠️ Setting Up Stable Diffusion with API Key
The paragraph provides a step-by-step guide on how to use Stable Diffusion, a generative AI model. It starts by instructing the user to obtain an API key from the Stability AI website, which involves logging in or creating an account if necessary. Once the API key is created, the user is guided to use a free Google Colab notebook, which is linked in the description. The user is then directed to add a new secret in the notebook's secrets tab, named 'SD_API_KEY', and to paste the API key there for access. The process includes running the notebook in steps to install dependencies and access the Stable Diffusion generator. The paragraph also touches on the credit system and the different models available for image generation, with a note on the Turbo model being cheaper but the full model being more effective with text.
