I asked GPT4 to refactor a simple, working python script for my smart lights... and it completely butchered the code and apologized mid-generation.
No amount of pleading or correction would get it to function as it did just a week or two ago.
It is so over.
People were saying the exact same thing a few weeks ago, and have been ever since it came out basically.
You having issues with one prompt or one conversation doesn't mean it's dumb now.
Still working fine for me.
Blowing up on reddit as well and tons of people agree: https://www.reddit.com/r/ChatGPT/comments/14ruui2/i_use_chatgpt_for_hours_everyday_and_can_say_100/?sort=new
Again, people were saying the exact same things over a month ago about how it had changed since a month ago at that point.
I've never had this issue until the last couple days.
Which just kinda proves my point that it probably didn't change that much, cause people were saying what you are saying months ago.
