A society of 25 artificial intelligence (AI) robots was observed waking up, making breakfast, going to work, going to a pub for lunch with friends, and even throwing parties, according to the six researchers who created the town for them.
Writing in an April 7 paper titled "Generative Agents: An Interactive Simulation of Human Behavior," researchers at Google and Stanford University built a virtual town inhabited by "generated agents" trained on ChatGPT. Acting". The goal of the research, which is yet to be peer-reviewed, is to create a small society of interactive AI robots inspired by life-simulation games like The Sims.
Agents can make broad inferences about themselves, other agents, and their Smallville town by synthesizing new information, storing it in memory, and then acting in ways that reflect that knowledge. For example, when agents see their breakfast burning, they can turn off their kitchen stove, coordinate plans, and even engage in seemingly meaningful conversations with other agents.
The results lead the researchers to conclude that generative agents produce "credible" human behavior: "By fusing large-scale language models with computable, interactive agents, this work introduces architectures and interaction patterns to enable trustworthy simulations of human behavior."
An example shared in the study explained that AI agent "Isabella Rodriguez" invited nine other agents to a Valentine's Day party at a coffee shop in town. Details of the reunion were passed on to four others, including "Abigail," who later expressed her excitement about the upcoming event with Isabella.
In another example showing a "day in the life" of an AI agent, "John Lin" wakes up at 7am, brushes his teeth, showers, eats breakfast, and checks the news at the living room dining table. Before John's son Eddie left for school, John asked him what he was going to do today. Eddy responded and John commented on the message before sharing it with his "wife" Mei. However, not everything works in experiments.
While each AI bot's memory expands with each interaction, sometimes the most relevant information isn't retrieved, and as a result, "some agents chose less typical locations for their actions." For example, when agents were deciding where to go for lunch, many initially chose coffee shops in town. However, the researchers stated:
"When some agents learned of a pub nearby, they chose to go there for lunch, although unless the town spontaneously developed an afternoon drinking habit, the pub was intended to be a meeting place later in the day."
In another example, some AI agents walked into a closed store in Smallville, while some college students walked into others in a dorm bathroom because they thought it might be occupied by people of multiple ages. The researchers say they will soon extend the "expressiveness" and "performance" of AI bots with the more advanced GPT-4, the latest version of ChatGPT, which passed the 90th percentile of US high school and law exams. quantile.
