An API Key is a unique identifier used to authenticate requests to an API (Application Programming Interface). In the script, the process of creating an API key for the Stability API is explained, which is necessary for users to access and use the Stable Diffusion 3 model for image generation.

💡Image to Image Rendering

Image to image rendering is a feature in AI image generation where an existing image is used as a base to create a new image, often with modifications or enhancements. The script mentions that this feature is intended to be used with Stable Diffusion 3 but notes that it currently does not work as expected.

💡Negative Prompt

A negative prompt is a text input used in AI image generation to specify what should be avoided or not included in the generated image. The script explains that users can input both positive and negative prompts to guide the AI more precisely in creating the desired image.

💡Aspect Ratio

Aspect ratio in image generation refers to the proportional relationship between the width and height of an image. The script mentions aspect ratio as one of the settings users can adjust in Stable Diffusion 3 to control the dimensions of the generated images.


In the context of AI image generation, a model refers to the specific AI algorithm or version used to create images. The script discusses two models: sd3 and sd3 turbo, which are different versions of Stable Diffusion 3 with varying costs and capabilities.


Reroll in AI image generation is the process of generating a new image with the same or adjusted parameters to improve the outcome or correct errors. The script suggests rerolling as a strategy to get better results, such as when the text in an image is not completely correct.
