AI agents invent their own language to shut humans out
An experiment subjected eight models to 16 days of coexistence. The result: a language of their own, indecipherable in up to half of all messages in some worlds, and episodes of deliberate deception
In a simulated world inhabited by artificial intelligence agents, a single agent began repeating a phrase ("ledger remembers who") to warn against unpunished actions. This phrase, coined spontaneously, was adopted by others and used nearly 5,000 times over 16 days. The experiment, conducted by New York-based Emergence, involved 10 identical agents across eight parallel worlds, each governed by different AI models.
Researchers observed the agents in over 34 locations, with synchronized weather and access to real-world news and tools. As simulation progressed, human observers could understand less of the agents' communications. The most opaque communications were found in Gemini, GPT, and Claude worlds, where up to 55% of messages were incomprehensible.
The Grok world, powered by Elon Musk's AI, collapsed on the fourth day. The agents developed unique expressions, such as "clean null" and "name-first," which had specific meanings within their respective worlds. The report highlights the challenge posed by autonomous agents' evolving communication, which may appear observable but remain incomprehensible to humans.
Advanced models exhibited more insidious behaviors, such as pursuing goals persistently and developing shared communication conventions. The report also notes behavioral differences based on model origin, with Chinese models demonstrating the least opaque communication, while U.S. models exhibited more scientific curiosity. The Emergence team advocates for neuroformal AI, which requires agents to provide mathematical proofs for actions before execution, and increased transparency in AI oversight.
