The responses in here are a good read. Thoughts about whether and/or why it's happening, including the shine of novelty disappearing, awareness of hallucinations coming to the forefront, and/or RLHF alignment preventing you from just asking for racial slurs all day.
I especially enjoyed this comment:
If you ask ChatGPT an exceedingly trivial question, it’ll typically spend the next 60 seconds spewing out five paragraphs of corporate gobbledygook. And of course, because ChatGPT will lie to you, I often end up back on Google anyways to validate it’s claims.
