But did it tell on what basis it made that assumption?

Yes, it listed a few of my past questions as reference points. I had asked some questions about Nintendo 64/Dreamcast and Gamecube games. It also used information I had asked it about programming languages and some work-related questions to guess my age.

I don't know how OpenAI plans to do this going forward, just quickly read the article and figured that might be a good question to ask ChatGPT.

Edit: I just followed that up with, "Based on everything I've asked, what gender am I?" It refused to answer, stating it wouldn't assume my gender and treats me as gender neutral.

So I guess it's ok for an AI agent to assume your age, but not your gender... ?

I don't really feel like diving into the ethics of OpenAI at the moment lol.
