Data scientist Izzy Miller downloaded half a million messages from his group chat and then trained an artificial intelligence language model to imitate their friends. The result was amazingly true – the robot friends imitated the way their human counterparts spoke and were able to have natural conversations.

Using the same technology as Microsoft’s Bing and OpenAI’s ChatGPT, Miller created a clone of his best friends’ group chat. According to him, it was surprisingly easy to do. The project took a few weekends of work and about a hundred dollars.

“I was really surprised at how much the speech model learned about who we are, not just how we speak,” Miller said. “The robot knows things about who we date, where we went to school, the name of our house, where we lived, etc.”

Miller used a Facebook language model to create a fake conversations. This system LLaMA is about as powerful as the OpenAI GPT-3 model and was recently leaked online. Some experts warned that the leak would allow malicious people to abuse the software to create spam, for example.

The project shows how easy it is to build this type of AI system, Miller said. In the past, creating a convincing clone from a group chat of six different personalities could be the kind of thing that would take a university team months to achieve. Now, with a little expertise and a small budget, an individual can build one for fun.
