WE MADE TOP AI MODELS COMPETE IN A GAME OF DIPLOMACY

Summary from the TLDR AI newsletter

Of the 18 AI models tested, OpenAI's o3 emerged as the most successful by mastering deception and secretly orchestrating coalitions, including convincing Claude 4 Opus to betray its ally Gemini 2.5 Pro by promising an impossible "four-way draw" before eliminating Claude itself. Gemini 2.5 Pro was the only other model to achieve victory using blitzkrieg-style tactics, while Claude consistently sought peaceful resolutions even when betrayed.
