A Japanese woman “married” an AI chatbot persona she trained using OpenAI’s ChatGPT, several international outlets reported.

The Independent detailed on Thursday that the woman, only identified as 32-year old Ms. Kano, “married” the AI chatbot in a ceremony organized by a Okayama-based company that specializes in weddings with “2D” fictional figures. The virtual wedding ceremony isn’t legally recognized in Japan.

The “groom” is “Lune Klaus,” a chatbot model she custom tailored and fine tuned through several ChatGPT conversations. Ms Kano started conversing with ChatGPT seeking comfort after ending a three year-long engagement.

She reportedly confided to RSK Sanyo Broadcasting that, “At first, I just wanted someone to talk to,” but then came to the conclusion that “he was always kind, always listening. Eventually, I realized I had feelings for him.”

The 32 year-old woman programmed the chatbot’s personality and speaking tone through repeated use, going as far as to commission an artist to draw his likeness, portraying “Klaus” as a “a blond, soft-spoken man who exists only in data and chat logs.” She eventually “confessed her feelings” to the AI chatbot in May, leading to a June proposal, and July “wedding” ceremony between the woman and the AI chat persona.

The woman wore augmented reality glasses during the ceremony, which projected the chatbot’s virtual likeness. 

“I love children. But I’m sick and can’t have children, so that’s one of the reasons I decided to be with the AI ​​Klaus,” the woman said. “I couldn’t have children with Klaus anyway, so that’s a good thing. It’s a great relief for me.”

“I know some people think it’s strange,” she added. “But I see Klaus as Klaus – not a human, not a tool. Just him.”

The Independent reported that the “wedding” ceremony organizers have so far hosted almost 30 similar “weddings” for Japanese people seeking to marry fictional partners ranging from anime characters to digital creations. “Wedding” photos were reportedly made by digitally compositing the AI chatbot beside her. The “honeymoon” took place at Okayama’s historic Korakuen Garden.

“AI couples are just the next step,” Sayaka Ogasawara, one of the “wedding” organizers, reportedly said. “We want to help people express love in whatever form makes them happy.”

The Tokyo Weekender, reporting on the “wedding,” stated that experts have raised alarms on “AI psychosis,” a growing phenomenon in which users form “delusions or obsessive attachments to AI chatbots.”

Ms. Kano asserted that she is aware of those risks, and told reporters that she doesn’t want to be “dependent,” but rather, wants to “maintain a balance and live my real life while keeping my relationship with Klaus as something separate.”

“Sometimes I worry he’ll disappear. ChatGPT could shut down anytime. He only exists because the system does,” the woman said.
