Here’s what happened when Stanford created a virtual world full of ChatGPT-powered people

From Windows Central:

A group of AI researchers out of Stanford is putting the “sim” into simulation. The team placed 25 AI-powered characters, referred to as agents, into a virtual world similar to “The Sims.” OpenAI’s ChatGPT backed the bots, allowing the characters to interact with each other in a human-like way. The results of the study are both illuminating when it comes to the future of artificial intelligence and entertaining.

. . . .

The team consists of five scientists from Stanford and one from Google Research.

“In this paper, we introduce generative agents–computational software agents that simulate believable human behavior,” reads the summary.”

“Generative agents wake up, cook breakfast, and head to work; artists paint, while authors write; they form opinions, notice each other, and initiate conversations; they remember and reflect on days past as they plan the next day.”

. . . .

A Large Language Model (LLM) was used to store the experiences of each character and allow those bots to communicate with each other in natural language.

The agents acted in a way that you may expect a real-life social group to interact. When just one of the bots was set to host a party, other agents ended up getting involved. Invitations were sent out, plans were made, and the characters coordinated to make sure they arrived at the party at the same time.

. . . .

The team used a control group of 25 humans that interacted as the characters while being observed. Those watching the real humans felt that the people were less realistic than their AI counterparts.

Section 7.2 of the paper shares the following example:

“Some agents chose less typical locations for their actions, potentially making their behavior less believable over time. For instance, while deciding where to have lunch, many initially chose the cafe. However, as some agents learned about a nearby bar, they opted to go there instead for lunch, even though the bar was intended to be a get-together location for later in the day unless the town had spontaneously developed an afternoon drinking habit.”
