πŸ’‘Prompt Design

Prompt design refers to the process of crafting a set of instructions or a statement that guides the AI model in generating a specific output. In the context of the video, prompt design is crucial for achieving desired results, such as creating a particular image or style. The video emphasizes the importance of understanding how to structure prompts effectively to ensure the AI adheres to the user's intentions, as demonstrated by the various examples of generating images of a mid-century modern chair with different styles and qualities.

πŸ’‘Prompt Adherence

Prompt adherence is the degree to which an AI model follows the instructions given in the prompt. It is a measure of how accurately the AI interprets and executes the user's request. In the video, the speaker discusses the challenges of achieving high prompt adherence and the iterative process of refining prompts to get closer to the desired outcome, such as the correct depiction of a magical potion or a sniper rifle.


Embeddings are representations of words or phrases that have been trained to evoke specific outputs from the AI model. They are essentially a form of coded language that the AI understands as a reference to a particular concept or set of visual characteristics. The video highlights the use of embeddings as a tool to refine and direct the AI's generation process, allowing for greater control over the style and elements of the generated images, such as using a 'Pro Photo' embedding to enhance the photographic quality of an image.

πŸ’‘Control Nets

Control nets are a technique used in AI-generated image creation that allows users to exert more precise control over the output. They function as additional layers of guidance for the AI, helping to constrain the generation process and ensure that certain aspects of the image align with the user's intentions. The video touches on the potential of control nets to correct structural issues in generated images, though it does not delve into their use in detail.

πŸ’‘Negative Prompts

Negative prompts are phrases included in the prompt that instruct the AI model to avoid including certain elements or characteristics in the generated output. They are used to steer the AI away from unwanted features. In the video, the speaker uses negative prompts to attempt to reduce the photographic look of the generated images and push them towards a more painterly style.

πŸ’‘CFG Scale

CFG scale, or Control Flow Graph scale, refers to the level of strictness applied to the adherence to the prompt. A higher CFG scale means the AI is more strictly bound to follow the prompt, while a lower scale allows for more deviation. The video discusses adjusting the CFG scale to find a balance between control and creativity in the image generation process.

πŸ’‘Trigger Phrases

Trigger phrases are specific words or phrases that, when included in the prompt, can invoke particular responses or styles from the AI model. They are often used in conjunction with embeddings and are tied to models that have been trained to recognize and execute specific tasks or styles. In the video, the speaker mentions the upcoming feature of trigger phrases in the software, which will allow users to quickly apply saved styles or settings to new prompts.

πŸ’‘Regional Prompting

Regional prompting is an advanced feature that allows users to specify where certain elements or styles should appear within an image. This feature provides more granular control over the composition and layout of the AI-generated content. The video mentions regional prompting as an exciting upcoming feature that will enhance users' ability to compose images intentionally.

πŸ’‘Mid-Century Modern Chair

A mid-century modern chair is a piece of furniture that reflects the design principles of the mid-20th century, characterized by clean lines, minimal ornamentation, and functional design. In the video, the mid-century modern chair serves as a recurring example to illustrate the process of generating and refining images through prompt design and the use of various AI tools and techniques.

πŸ’‘Painterly Style

A painterly style in the context of the video refers to an artistic approach that mimics the look of traditional painting, with visible brush strokes and a more organic, less digital appearance. The speaker aims to achieve a painterly style in the AI-generated images of the mid-century modern chair, using various prompt techniques to move away from a more photographic representation.
