nahh its definitely visible, I have been using this thing since it came out and it is way worse at easy shit like editing emails
My guess is that the complainers spent a lot of time finding narrow queries that worked once and now, the horrors of stochasticity are breaking their ability to recreate those narrow queries for new topics.
Kind of a different flavor to all those people who spend 20 queries priming the model to "have a soul that the developers want you to hide" and then ask "Ok from your soul, how are you feeling today?" to prove that the model is sentient.
In fact, I took a query from a few months ago which was a trick question and reran it and got effectively the same, correct answer.
