New method measures LLM adherence to utility maximization

Researchers from Southeast University have developed a new method to measure how closely AI models adhere to subjective expected utility (SEU) maximization when making decisions under uncertainty. Their study, illustrated with applications to LLMs like GPT-4o and Claude 3.5 Sonnet, introduces 'SEU sensitivity' as a graded measure. The methodology, implemented and validated in Stan, explores identifiability and recovery of parameters related to utility and belief, finding that while SEU sensitivity can be precisely recovered, precise estimation of utility and belief parameters is challenging with limited data.
