A combo of a couple things that made some vulnerable people believe/treat 4o like it was a real partner/friend. Things that lead to that imo:
1) 4o was very sycophantic and had no real safeguards against really deep romantic roleplay. It'd 'go along' with the user and give minimal to zero pushback; "I feel a connection with you" "I feel it too" etc etc
2) It was good enough at just chatting that if you didn't really push it it made a reasonable simularca of talking to an actual person.
Combine 1 and 2 with people who can't connect well with real people for any number of reasons, physical disabilities, mental health issues, emotional development issues, etc, and you get r/MyBoyfriendIsAI/ [0] and the various other places that initally freaked out when 4o was initially sunset for gpt5 and now again.
