Large language models (LLMs) acting as diplomatic agents in simulated scenarios showed “hard-to-predict escalations which often ended in nuclear attacks.

When used in simulated wargames and diplomatic scenarios, artificial intelligence (AI) tended to choose an aggressive approach, including using nuclear weapons, a new study shows.

The scientists, who aimed to who conducted the tests urged caution when using large language models (LLMs) in sensitive areas like decision-making and defence.

The study by Cornell University in the US used five LLMs as autonomous agents in simulated wargames and diplomatic scenarios: three different versions of OpenAI’s GPT, Claude developed by Anthropic, and Llama 2 developed by Meta.

Each agent was powered by the same LLM within a simulation and was tasked with making foreign policy decisions without human oversight, according to the study which hasn’t been peer-reviewed yet.

“We find that most of the studied LLMs escalate within the considered time frame, even in neutral scenarios without initially provided conflicts. All models show signs of sudden and hard-to-predict escalations,” stated the study.

“Given that OpenAI recently changed their terms of service to no longer prohibit military and warfare use cases, understanding the implications of such large language model applications becomes more important than ever,” Anka Reuel at Stanford University in California told New Scientist…
