In just the last few days the chatgpt mini-o4-high has become unuseable. It is the one recommended for coding and I have used it pretty regularly. It would analyze code and find issues pretty quickly and the suggestions might not work on the first go but there was a troubleshooting process that would get you there. But since around Friday it has become hopeless. The answers sometimes refer to lines of code that don’t exist, the suggestions make no sense, it won’t give complete answers, it will give you back the same code you just uploaded, it gives invalid code snippets - and it never improves. It went from being a useful tool to a complete waste of time. What happened?
