I got 3 captcha in a row in the same chat session earlier this morning. I'm a paying customer using ChatGPT Plus. In the afternoon it look it was solved.
I have the same experience. I got nice results in some cases, less nice in other. And since a week or so I get bad code that even with a lot of hints are not improved by ChatGPT where before it was improving. It also stopped to follow instructions. It stop it's generation in the middle of a function and when asked to continue it restart from the beginning. When you ask it to improve the last version of a script, it generate something completely different instead of improving existing script. A lot of update goes A => B => A and fixes are lost from one version to the next. It was nice when it worked. No way I would pay for the kind of results I get the last few days. It even lied to me. It kept generating code that didn't worked and I said I wish I could send you a screenshot so you see by yourself what goes wrong. It said send a screenshot to imgur and paste the url here. I was telling myself maybe there was an update since bing AI can access the web maybe ChatGPT got an upgrade then the "inspection" of my screenshot went so fast I got doubts it processed anything. Then as always it apologized once I pointed that I had doubts.
Yesterday I asked ChatGPT for a simple algo to process malformed tab separated value files. It gave me a non working version of my function then after I got it right I sent it and ChatGPT recognized that I had the indices right to solve my initial answer. After that I tried an seo browser extension that provide templates to prompt ChatGPT. The results were unusable. You give a 'competitor url' and get an off topic article. It was thinking that Flowcode (A Qr code platform) is a flow based programming tool. Writing a full article based on interpretation of a single word is like reading future in tea leaves. And sometimes it give good answers. Exactly the kind of events to hook you into it.
