<abstract>We introduce a novel framework, LM-Guided CoT, that leverages a lightweight (i.e., \textless1B) language model (LM) for guiding a black-box large (i.e., \textgreater10B) LM in reasoning tasks. Specifically, the lightweight LM first generates a rationale for each input instance. The Frozen large LM is then prompted to predict a task output based on the rationale generated by the lightweight LM. Our approach is resource-efficient in the sense that it only requires training the lightweight LM. We optimize the model through 1) knowledge distillation and 2) reinforcement learning from rationale-oriented and task-oriented reward signals.
