The most fun way I’ve seen users explore its origin is to give it a single period (”.”) as your first query. Only OpenAI answers in this way with a smiley at the end, and it’s probably a more certain way to check it than asking about its arch, because many will incorrectly answer OpenAI and GPT-4 due to (?) tainted training data as ChatGPT has been so much in the news and became a de facto LLM early.
