Feature Request: Add Vector Retrieval Capabilities

[cbarber713]

I propose enhancing our AI system by implementing an assistant-like functionality with vector retrieval capabilities, similar to the OpenAI Assistants API.

Vector retrieval would allow the AI to provide more relevant and accurate answers by considering the context of queries.

Does OpenAI plan to add this directly at some point?

This is probably out of the scope of this sample repo's goals.
