This is the SD1.5 Plus model of IP Adapter. It requires the SD1.5 IP Adapter encoder to be installed to function correctly. It is compatible with version 3.2+ of Invoke AI.
The IP Adapter Plus model allows for users to input an Image Prompt, which is then passed in as conditioning for the image generation process.
The Plus model is not intended to be seen as a "better" IP Adapter model - Instead, it focuses on passing in more fine-grained details (like positioning) versus "general concepts" in the image.
The Community Edition of Invoke AI can be found at invoke.ai or on GitHub at https://github.com/invoke-ai/InvokeAI
