node-RED is one option that is Apache 2 licensed and has about 4800 plugins. Recently picked up a contract where node-RED was a requirement. It is not specific to AI, but there are multiple nodes for ChatGPT etc. In the current project I build up a prompt using `template` nodes that include the `payload` from previous nodes in a chain. Although there are other ways of doing it. Then that is connected to the chatgpt node.
