๐Ÿ’กStable Diffusion

Stable Diffusion is a term referring to a type of machine learning model used for generating images from textual descriptions. In the context of the video, it is the core technology that the speaker is utilizing to demonstrate how different prompts can affect the output images. The speaker discusses how varying the wording in prompts can lead to significant changes in the generated images, showcasing the nuances of Stable Diffusion's capabilities.

๐Ÿ’กWriting Prompts

Writing prompts are starting points or stimuli that encourage creative writing or thinking. In the video, the speaker uses writing prompts to guide the Stable Diffusion model to create specific types of images. The prompts are composed of various keywords that influence the model's output, and the video explores how to strategically use these prompts to achieve desired results.


Keywords are significant words or phrases that are used to direct the Stable Diffusion model to generate images with particular characteristics. The video emphasizes the importance of choosing the right keywords from different categories to guide the image generation process. Examples from the script include using 'charcoal drawing' or 'watercolor painting' to specify the desired art medium.


In the context of art and the video, medium refers to the material or technique used to create an artwork, such as charcoal, watercolor, or digital. The speaker demonstrates how specifying the medium in the prompt can drastically change the style of the generated images, such as changing from a charcoal drawing to a watercolor painting.

๐Ÿ’กArt Style

Art style refers to the distinctive visual language or aesthetic that characterizes an artwork or an artist's work. The video discusses how including a specific art style in the prompt can influence the output of the Stable Diffusion model. For instance, changing the prompt to request an 'abstract painting' results in a different type of image compared to a 'realistic painting'.


An artist, in this context, refers to a specific individual known for their unique style or approach to creating art. The speaker shows that naming an artist in the prompt can significantly affect the style of the generated images, as the model associates certain styles with specific artists. For example, using 'Agnes Cecil' in the prompt results in images that resemble her painting style.


Resolution in the context of digital images refers to the level of detail or clarity present in the image. The video mentions using terms like 'highly detailed' or '4K' in the prompt to direct the Stable Diffusion model to generate images with more intricate details.


Attributes are descriptive characteristics or qualities that can be used to define the subject of the image. In the video, the speaker adds attributes such as 'Chinese woman' or 'age 80' to the prompt to generate images with specific features or demographics in mind.


Color is a powerful keyword that can be used to direct the overall hue or palette of the generated images. The speaker illustrates this by changing the color in the prompt from 'cream' to 'orange', which results in images with a dominant color scheme that matches the specified keyword.


Lighting refers to the way in which light interacts with the subject in an image, affecting the mood and atmosphere. The video demonstrates the impact of using lighting-related keywords such as 'Golden hour' or 'nightly picture in the moonlight' in the prompt, which can significantly alter the ambiance of the generated images.

๐Ÿ’กTrial and Error

Trial and error is a method of problem-solving where various solutions are tried and the less effective ones are eliminated through a process of repeated testing and refinement. In the context of the video, the speaker emphasizes that despite the analytic approach to using keywords, there is still an element of trial and error involved in achieving the desired image through Stable Diffusion.
