Dynamic Mixed-Precision Routing for Efficient Multi-step LLM Interaction

Huanrui Yang, Jianing Deng, Jingtong Hu, Song Wang, Tianlong Chen, Yuanzhe Li

Dynamic mixed-precision routing lets LLMs switch between high and low precision at each step to cut costs while keeping task success high.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Experiments on ALFWorld and WebShop demonstrate that our approach achieves a strong accuracy-cost trade-off over single-precision baselines.

C2weakest assumption

The observation that interaction steps have diverse sensitivities to precision allows a router to be trained that reliably selects the right precision level without harming overall task success.

C3one line summary

DMR uses a router trained in two stages (KL-divergence supervision then GRPO) to pick high or low precision LLMs per step, delivering better accuracy-cost trade-offs than fixed-precision baselines on ALFWorld and WebShop.
