Don’t ask it how its system works or what models it uses. Its knowledge is limited to what was included in its training data or added to its instructions, so it won’t know what happened recently unless it was told.
It can use web search to find current information online.
If you want to check which model you’re using, read this link and try on your end what I told there
and ask the GPT-4o model. It might say “GPT-4 Turbo” in the reply, but the JSON response will show “gpt-4o” as the model name, which is correct.
Don’t waste time asking it about itself. Just use the AI and get what you need from it.
