Over the last week or two, I've found ChatGPT4 dramatically less usable. Replies take a while to start and come back at half the speed they did before. Many replies fail. I click the button to "regenerate" them, but that almost always fails. I've started abandoning ChatGPT to use the services I used to use.
I'm accustomed to new product having growing pains. (I'm 50 years old, have a Masters in CS, have published research, and used all kinds of new tech.) I can understand slow. But the repeated failures is bad. Especially for a product I'm paying for after being on a wait list.
