what's difference between ChatGPTPluginRetriever and VectorStore Retriever

[JIAQIA]

I have a question about ChatGPTPluginRetriever and LangChain VectorStore Retriever. I wanner use Enterprise Private Data with chatGPT, several weeks ago, there is no OpenAI chatGPT Plugin, I intend to use LangChain Vector Store implenment this function, but I have not finish this job, chatgpt plugin come true, I have read chatgpt-retrieval-plugin README.md, but don't have enough time to research code detail, I want to know, what's difference between ChatGPTPluginRetriever and VectorStore Retriever.

I guess ChatGPTPluginRetriever means if you implement "/query" interface, chatGPT will request it with questions intelligently, just like chatGPT will ask question in one of its "Reasoning Chains". But LangChain VectorStore will work independent. Does anyone konws is that so? thanks very much.

P.S. English is not my mother tongue, so I have a poor English. Sorry for that ^_^
