I'll anecdotally say that Copilot doesn't give me solutions that work nearly as well lately. It used to be the case that I could have it generate whole classes by prompting only the method signatures. Now it can hardly generate a single function without needing fixes for things like hallucinated variables (in its own code!) or invalid syntax. Even just getting it to output the correct number of closing braces/parens has gotten noticeably worse.
