Any pleb who can confirm if the Chat GPT is giving you lower quality answers then used to?

Missing variables, keeps repeating the same mistakes, hallucinating more often then usually... Basically I'm certain 4 has been downgraded.

I usually fix the code bugs easily but now I'm getting nowhere.

I really don't see any difference between 3.5 and 4 after the word lawsuit is upon OpenAI and Microsoft.
