GPT-5 is so bad.
I asked for an app that could rsync photos from my iPhone to my Linux machine. It gave me some suggestions, but the apps were too old and didn’t work with modern authentication. So I said, “Forget about rsync as a tool—what I actually want is an rsync-like experience.” GPT-5 then gave me another list of suggestions, with examples of how to use them. But at the end of each example it cheerfully added, “And after this, you can run rsync.” That made no sense at all!
Another time, it suggested using YAML and some algorithmic way to process English text. I pointed out that we could just use a Large Language Model (LLM) instead of regex and keyword parsing. That way, we wouldn’t even need YAML—we could just write the rules in plain English. GPT-5 agreed… but then still suggested using YAML as part of the prompt! Grrr…
