💡Steerable Diffusion

Steerable Diffusion is a term related to AI-generated art, referring to a technique that allows for control over the generation process by adjusting parameters. In the context of the video, it is used to fine-tune the AI's output to achieve the desired visual result. The script mentions 'スティーブルディフュージョンWEBUI' (Steerable Diffusion Web UI), indicating the use of a user interface for this purpose.

💡AI Artwork

AI Artwork refers to the creation of visual art using artificial intelligence. In the video, the creator is using AI to generate images, experimenting with different prompts and parameters to achieve a desired aesthetic. The process involves overcoming challenges such as '壊れる' (breaking) or '指がおかしくなったり' (funny fingers), which are common issues when AI tries to depict complex human actions like eating ramen.


In the context of AI-generated art, a prompt is a set of instructions or keywords that guide the AI in creating an image. The script mentions creating prompts and adjusting them to steer the AI's output towards the creator's vision. For example, the term 'プロンプト' (prompt) is used when discussing how to make the AI generate an image of a sister character and when trying to get the AI to draw a person eating ramen correctly.

💡Negative Prompt

A negative prompt is used in AI-generated art to specify what elements should be avoided or excluded from the final image. In the script, it is implied that the creator uses negative prompts to prevent certain unwanted features, such as '手が壊れていない' (hands not broken), to ensure the AI generates more accurate and realistic images.


Upscaling refers to the process of increasing the resolution or size of an image without losing quality. In the video, the term 'アップスケール' (upscale) is used when discussing how to enhance the quality of the AI-generated images. The creator aims to select the best images from multiple outputs and then upscale them to achieve a higher level of detail and clarity.
