Yep, for example I think the joke about a guitarist fingering a minor is gone now from it’s repertoire. Finetuning and guardrails probably also limit its capability to “understand” jokes in general.

IME it’s explanations of jokes are usually really off too, probably partly because of the guardrails and partly because it’s understanding is so surface level.

Edit: tried to see if understands the joke about guitarist but now it refuses to even explain it and just flags the question and freezes.
