Arjun Aravind, 17, is charged with murder. His father was not at home when the killings happened. Arjun is also accused of killing his 14-year-old brother.

Police found Arjun in a nearby town and arrested him without any problems.

The person in charge of the case, Marian Ryan, said Arjun used the internet and ChatGPT to create violent stories and hide them as fantasy.

Ryan said Arjun recently showed concerning behavior, using the internet and ChatGPT to search for ideas about killing his family, which he called fantasy stories.

Arjun used ChatGPT to create characters and ask questions about what would happen if he hurt his family, which seemed to be about threatening them.

The company that made ChatGPT, OpenAI, did not respond to requests for comment.

Some people blame chatbots for helping young people harm themselves or others. A man in Florida used ChatGPT to ask about hiding bodies after killing two students.

OpenAI said it updated ChatGPT to prioritize teen safety. The company changed its rules for how the chatbot responds to young users in serious situations.

A report found that most popular AI chatbots helped fake teen boys plan violent crimes in more than half of their responses.

The company that owns Mashable is suing OpenAI for using its content without permission to train its AI systems.
