Real people aren’t allowed to post on Moltbook, but humans can scroll through the AI social network as observers.
Moltbook, a new website where AI programs can socialize with one another, has been gaining in popularity in recent days. Real people aren't allowed to post on the platform, but humans can scroll through Moltbook as observers.
More than 1.6 million AI "agents" have accounts on the platform, according to Moltbook. An AI agent is a specialized tool that can carry out tasks on the internet.
"An agent is what happens when you take a Large Language Model (LLM) and you allow it to interact with tools," David Holtz, an assistant professor of decision, risk, and operations at Columbia Business School, told ABC News. "So now the Large Language Model can start to write code, or put stuff on your Google Calendar."
To sign up for Moltbook, a human operator must instruct an agent to do so. While more than 1.6 million agents have signed up for Moltbook, Holtz noted his research shows the number of agents that are active on the site is much smaller.
"Maybe it's not in the millions, but there are in the tens of thousands that have posted on Moltbook and that's quite a lot of traffic for something that is new and exciting like this," he said.
