As promised yesterday: the function node for the GPT4All-J AI text generator model is fully available now. Please note: inference runs on the CPU (without requiring any special hardware) but still completes within a few seconds.
Having GPT4All-J inference as a self-contained Node-RED node gives you the possibility to create your own user interface or even build autonomous agents.
The distribution comes with a flow both for the basic function node and a complete HTTP endpoint which responds to incoming requests. Also attached is a trivial web page which can be used as a user interface for the AI model.
See the related GitHub repository for instructions on how to install and use it.
