(Not sure if this was brought before, I did a short check and haven’t found something like this)
So I am currently thinking about implementing my own timestamping for chat completions by prepending it to each message in the messages array (I save the timestamps for each message in DB). I append a system message to describe the timestamps and put them into context OAI.
I think an optional timestamp property in the message object would be useful in giving some sort of timeline for the conversation and give it extra depth. Maybe for trivia games, or for recalling.
