- Researcher Nataniel Ruiz, recovering from surgery, found ChatGPT's latest versions "extremely paranoid": even for mild issues it escalates, urging users to contact doctors and authorities at 11 pm on a Saturday.
- Claude is far more chill and balanced, but doesn't go the extra mile on technical troubleshooting (e.g. Steam Deck debugging), where ChatGPT does find fundamental issues easily searchable online.
- He suspects a fundamental pre/post-training difference produces these large personality gaps — hard to get the best of both worlds.
