For developers, I should also mention Bing Chat seems to be in the lead for asking questions like, "In this <github repo link>, can you tell me what this function does <function name>?" (or insert your own question you might ask another developer about some repo). I suspect this is because Microsoft has already done the chunking/embedding/vector-storage for all of Github and Bing Chat is querying a vector database for info about the repo, whereas the other GPT-search-chat offerings aren't there yet.
