LLMs Choose the Safer Gamble Yet Price the Riskier One Higher

A study involving four large language models—Claude Opus 4.7, DeepSeek V4-Pro, Google Gemini 3 Flash Preview, and OpenAI GPT-5.5—revealed a pattern of inconsistent decision-making. The models frequently chose a safer option with a smaller reward but then assigned a higher value to a riskier option with a larger potential payoff. This behavior mirrors human preference reversals observed in psychological studies from the 1970s, indicating a potential bias in how LLMs evaluate gambles. AI
