Researchers just tested whether AI models can be strategic reasoners by running 140,000 Prisoner's Dilemma decisions — discovering that models from OpenAI, Google, and Anthropic each developed unique strategic approaches.
Seeing LLMs develop distinctive strategies while being trained on the same literature is more evidence of reasoning capabilities over just pattern matching. As models handle more high-level tasks like negotiations, resource allocation, etc., different model ‘personalities’ may lead to drastically different outcomes.
