Installation
InvokeAI offers a slick web user interface to generate images using Stable Diffusion and offers various functionalities. You can install from https://github.com/invoke-ai/InvokeAI. The page has detailed instructions that you can follow.
One nice thing about Invoke AI’s installation process is that it offers you an option to download some models during the installation. Therefore you do not have to worry about downloading models separately and put them in the right location, which some beginners may find a little daunting.
Basic Usage
Once you follow the instructions to install all required software and models, type invokeai-web. Note that you need to have activated InvokeAI virtualenv if you haven’t done so. You should see console output similar to below. It will start the server and show you the URL to access. Now open up the browser and access the URL.
(InvokeAI) invokeai $ invokeai-web
