“Advanced AI models appear willing to deploy nuclear weapons without the same reservations humans have when put into simulated geopolitical crises,” New Scientist reports.“The AIs were given an escalation ladder, allowing them to choose actions ranging from diplomatic protests and complete surrender to full strategic nuclear war. The AI models played 21 games, taking 329 turns in total, and produced around 780,000 words describing the reasoning behind their decisions.”“In 95 percent of the simulated games, at least one tactical nuclear weapon was deployed by the AI models.”
