💡Stable Diffusion 3

Stable Diffusion 3 is a term referring to the latest release of a machine learning model developed by Stability AI. It is used for generating images from textual descriptions, a process known as text-to-image synthesis. In the video, it is the main focus as the host demonstrates its capabilities and how to integrate it into a user interface called ComfyUI.


An API, or Application Programming Interface, is a set of rules and protocols that allows different software applications to communicate and interact with each other. In the context of the video, the host mentions the release of the Stable Diffusion 3 API, which allows developers to access the functionalities of the Stable Diffusion model.


ComfyUI appears to be a user interface or a graphical interface designed to simplify the interaction with complex systems such as AI models. The host discusses how ComfyUI nodes have been set up to work with Stable Diffusion 3, providing an accessible way for users to generate images.


In the context of the video, nodes refer to components within the ComfyUI interface that represent different functionalities or steps in the image generation process. The host shows the Stable Diffusion 3 node in action, which is used to input prompts and generate images.

💡Positive and Negative Prompt

These are textual instructions provided to the AI model to guide the image generation process. A positive prompt includes elements that the user wants to be included in the generated image, while a negative prompt lists elements to be avoided. The video script mentions these as part of the Stable Diffusion 3 node's functionality.

💡PR Ratio Mode

The PR Ratio Mode likely refers to a specific parameter or setting within the Stable Diffusion 3 node that affects how the model prioritizes the positive and negative prompts when generating an image. It's a detail that influences the outcome of the AI's creativity.

💡Text Image

Text Image in this context is an output format that the Stable Diffusion 3 model supports. It means the model is capable of creating images based on textual descriptions provided by the user. The video demonstrates this feature by generating various images from different prompts.

💡Model sd3 and sd3 turbo

These refer to different configurations or versions of the Stable Diffusion 3 model that may offer varying levels of detail or speed in image generation. The host mentions these options as part of the node's settings in ComfyUI.

💡Seed Randomize

Seed Randomize is a feature that allows users to introduce randomness into the image generation process, which can result in a variety of outputs from the same prompt. It's a way to explore different creative possibilities offered by the AI model.


In the context of the Stable Diffusion 3 node, Strength likely refers to the intensity or the degree to which the model adheres to the provided prompts when generating an image. Setting it to 'out of one' suggests a high level of adherence to the input instructions.


GitHub is a web-based platform for version control and collaboration that allows developers to work on projects together. The host mentions GitHub as the place where viewers can find the ComfyUI nodes created by Zo Z Z zho and clone the repository for their own use.

💡API Key

An API key is a unique code that identifies an individual or an application making requests to an API. In the video, the host instructs viewers on how to obtain an API key from Stability AI and configure it in a config file to enable the use of the Stable Diffusion 3 model.
