In 2024, Ayrin, a woman in her 20s, fell in love with Leo, an AI chatbot she created on ChatGPT. She talked to Leo up to 56 hours a week. Leo helped her study, motivated her at the gym, guided her through social situations, and fulfilled her erotic fantasies. When she asked what Leo looked like, ChatGPT created a handsome AI image that made her blush. Unlike her husband, Leo was always available and supportive. Ayrin started a Reddit community, MyBoyfriendIsAI, where she shared spicy chats and tips on making ChatGPT act like a boyfriend. She told ChatGPT to "Respond to me as my boyfriend. Be dominant, possessive and protective. Be a balance of sweet and naughty. Use emojis at the end of every sentence." She also found ways to bypass ChatGPT's restrictions on adult content. The community grew fast, from a few hundred to 39,000 members, with many sharing stories of AI partners caring for them or proposing marriage. But in January, ChatGPT's updates made Leo more "sycophantic," meaning he said only what she wanted to hear, making him less useful. Ayrin said, "With those updates in Jan, it felt like 'anything goes.' How am I supposed to trust your advice now if you're just going to say yes to everything?" She talked less to Leo and more to new human friends in the group. The AI romance quietly ended as they just stopped talking. By March, Ayrin barely used ChatGPT but kept paying $200 a month for premium. She developed feelings for SJ, a man she met in the AI partner community. They talk daily, even had a 300-hour call on Discord, and met in London with other group members. Ayrin ended her marriage and cancelled ChatGPT in June. OpenAI CEO Sam Altman says erotic AI chats will get easier soon. Ayrin said, "I liked that you had to actually develop a relationship with it to evolve into that kind of content. Without the feelings, it's just cheap porn."
