๐Ÿ’กKrita AI image generator

The Krita AI image generator is a plugin for the Krita digital painting software that integrates AI technology to assist users in generating images. It is designed to work with the open-source image generation software, Stability AI, and serves as a bridge between Krita and the AI software. This tool allows users to generate high-quality images through various features such as text-to-image generation, image expansion, and upscaling. The plugin is particularly useful for artists and designers looking to enhance their creative process with AI capabilities.

๐Ÿ’กStability AI

Stability AI is an open-source image generation software that enables users to create images from text descriptions. It is not exclusively tied to Krita and can be used with other interfaces as well. The software utilizes AI algorithms to generate detailed and realistic images based on the input provided by the user. The video script mentions that Stability AI is a crucial component in the functionality of the Krita AI image generator plugin.

๐Ÿ’กGenerative fill

Generative fill is a function within the Krita AI image generator plugin that allows users to fill selected areas with AI-generated content. This feature can be used to create complex textures, patterns, or entire scenes with minimal input, leveraging the power of AI to produce detailed and varied imagery. It is a timesaver for artists, as it automates the process of creating intricate details that would otherwise require significant manual effort.

๐Ÿ’กText-to-image generation

Text-to-image generation is a feature of the Krita AI image generator that translates textual descriptions into visual images. Users can input a prompt or a concept described in words, and the AI will generate an image that corresponds to the description. This capability is particularly useful for quickly conceptualizing ideas or creating drafts for more refined artwork.

๐Ÿ’กImage expansion

Image expansion is a process where an existing image is enlarged while maintaining or improving its quality and detail. The Krita AI image generator's image expansion feature allows users to extend the boundaries of an image, adding new content that complements the original scene. This can be particularly helpful for creating backgrounds or panoramas where a larger canvas is desired.


Upscaling refers to the process of increasing the resolution of an image while attempting to maintain or improve its quality. In the context of the Krita AI image generator, upscaling is a feature that allows artists to enlarge their work to higher dimensions without losing detail or clarity. This is especially beneficial when preparing images for print or digital platforms that require higher resolution.

๐Ÿ’กControl net

Control net is a technical feature utilized within AI image generation software, including Stability AI, to guide the output based on user input. It functions as a neural network that helps refine the AI's understanding of the desired image, ensuring that the generated content aligns more closely with the user's specifications. This feature is crucial for achieving precise results in AI-generated images.


VAE, or Variational Autoencoder, is a type of artificial neural network used for efficient learning and compression of data. In the context of AI image generation, VAE is used to create new data points that are similar to the input data, which can be used to generate new images that are stylistically consistent with the training data. It is a valuable tool in ensuring that the AI-generated images maintain a level of coherence and quality.

๐Ÿ’กSD and XL models

SD (Standard Definition) and XL (Extra Large) models refer to different sizes of AI-generated images. SD models produce images with a resolution of up to 512 pixels, while XL models can generate images with a resolution of up to 1,024 pixels. These models cater to different needs, with SD models being faster to generate and suitable for smaller applications, and XL models providing higher resolution for more detailed or larger images.

๐Ÿ’กInstallation process

The installation process refers to the steps required to set up and integrate the Krita AI image generator plugin into the Krita software. This involves downloading the installation file, ensuring system compatibility, and following specific instructions to place the plugin files in the correct directory. A successful installation process is essential for the plugin to function correctly and provide its intended features.

๐Ÿ’กCustom models

Custom models refer to user-created or third-party developed AI models that can be installed and used within the Krita AI image generator. These models can offer different styles, levels of detail, or specific functionalities that may not be available in the default models. By installing custom models, users can expand the capabilities of the AI image generator to better suit their individual needs and preferences.
