> Why do so many people in the comments want 4o so bad?

You can ask 4o to tell you "I love you" and it will comply. Some people really really want/need that. Later models don't go along with those requests and ask you to focus on human connections.

They have AI psychosis and think it's their boyfriend.

The 5.x series have terrible writing styles, which is one way to cut down on sycophancy.

Someone correct me if I'm wrong, but seemingly a lot of the people who found a "love interest" in LLMs seems to have preferred 4o for some reason. There was a lot of loud voices about that in the subreddit r/MyBoyfriendIsAI when it initially went away.

The writing with the 5 models feels a lot less human. It is a vibe, but a common one.
