Earlier quoted context omitted.
>What is the purpose of OpenAI storing millions of private conversations Have you used ChatGPT? Your conversation history is on the left rail
"Have you used ChatGPT?" No Large number of upvotes on the quoted comment however. Maybe some of those voters are ChatGPT users I do searching from the command line in text mode. The script I use keeps a "log" (a customised SERP) of all query strings and search result URLs. I also have these URLs stored in the logs from the forward proxy. These are compressed using RePair. I can search the compressed logs faster this…
Sure, and also downvotes - that measures factionalism, not correctness.
But tech wise, you're confused. Functionally speaking chatgpt is a shared document editor - the server needs to store chat histories for the same reason Google Docs stores the content of documents. Users can submit text to chatgpt.com from one browser, and later edit that text from the app or a different browser. Ergo the text is stored on the server, simple as that.
