If you go to the Internet Archive's "Wayback Machine", it appears that looking at previous saves for the "chatgpt.com" website, after OpenAI's acquisition, have default responses from ChatGPT for each day

For example, August 1st 2024 has any message replied with the answer "It seems like you've mentioned "Glen Mulroney." If you're referring to someone specific or have a question about them, could you please provide more context?" https://web.archive.org/web/20240801000429/https://chatgpt.com/

Different days have different responses, it's pretty interesting!
