Hunter Lightman
OpenAIMember of Technical Staff
Lightman helped make process supervision practical for mathematical reasoning: instead of judging only a final answer, a model learns from feedback on each reasoning step. His work produced the PRM800K dataset and informed OpenAI's broader effort to make advanced reasoning models more reliable.
