Thanks for this info! Regarding the first instance of a non-LangChain Retriever - the ChatGPT Retrieval Plugin. I know this was recently open sourced by OpenAI for their own purposes to help gain more traffic to them. Probably to help people figure out endpoints to hook into ChatGPT. But how about for other usages? Be interested in how this fits in with your vectorstores. Thanks for the read!
