Optimal Bayesian Stopping for Efficient Inference of Consistent LLM Answers

Researchers propose a Bayesian stopping strategy that reduces LLM inference costs by up to 50% while maintaining answer accuracy. The method samples multiple LLM responses and stops once sufficient consistency is detected, using an efficient L-aggregated policy that tracks only the top 3 answer frequencies and achieves theoretical optimality.
