These answers don’t use OpenAI technology. The yes and no snippets have existed long before their partnership, and have always sucked. If it’s GPT, it’ll show in a smaller chat window or a summary box that says it contains generated content. The box shown is just a section of a webpage, usually with yes and no taken out of context.

All of the above queries don’t yield the same results anymore. I couldn’t find an example of the snippet box on a different search, but I definitely saw one like a week ago.
