I'm confused how this is even supposed to demonstrating "metacognition" or whatever? It's not discussing its own thought process or demonstrating awareness of its own internal state, it just said "this sentence might have been added to see if I was paying attention." Am I missing something here? Is it just that it said "I... paying attention"?
This is a thing humans already do sometimes in real life and discuss -- when I was in middle school, I'd sometimes put the word "banana" randomly into the middle of my essays to see if the teacher noticed -- so pardon me if I assume the LLM is doing this by the same means it does literally everything else, i.e. mimicking a human phrasing about a situation that occurred, rather than suddenly developing radical new capabilities that it has never demonstrated before even in situations where those would be useful.
When people say stuff like this it always makes me wonder "what pace, exactly?" Truthfully, I feel like hearing someone say "well, generative AI is such a fast-moving field" at this point is enough on its own to ping my BS detector.
Maybe it was forgivable to say it in May 2023, but at this point it definitely feels like progress has slowed down/leveled off. AI doesn't really seem to me to be significantly more capable than it was a year ago -- I guess OpenAI can generate videos now, but it's been almost a year since "will smith eating spaghetti," so...
