No, OpenAI 100% pushed an update recently that is very noticeable where they basically "nerfed" the responses. I'm sure it was a business decision (either costing them too much to give away the kitchen sink for free or they want to turn around and charge more for the "really good, old" version of GPT-4 ) but you can visually see where the bot used to try to answer complex tasks, now it has an extra layer where it says "that is too complex to discuss here" (aka it is being trained to not engage by default, whereas that used to not be the case)
