InvokeAI is an open-source AI model that allows you to create images from text prompts. It utilizes the Stable Diffusion AI model, which generates high-quality images based on the provided text input. The project is hosted on GitHub, and users can run the InvokeAI application locally or on a cloud instance.
GitHub is the leading git-based development platform for hosting, reviewing, and managing software code and projects.

InvokeAI is an open-source project and is free to use. However, users may need to pay for cloud computing resources or GPU hardware if running the application on their local machines is not feasible.
