GPT has been severely downgraded

I am also seeing problems with coding. Previously I could paste 50-100 lines of code and event that a few different versions say 3 x 50-100 and could have a decent conversation and get problems resolved. For example if I have a flask service in Python and a javascript html front-end. It very quickly forgets the pasted Javascript and makes stuff up. I have noted this from yesterday. Its hard to give or paste specific examples but its recall is degraded and its suggestions for coding are lacking - I have ok keep steering it. It is giving generalized solutions. I checked it it has recall of earlier code and it does, but it seems to ignore it and go for a more generic solution ignoring specifics. I hope that helps.
