SWEET-RL: Training LLM Agents for Collaborative Reasoning
from Best AI papers explained Hosted by Enoch H. Kang
This research paper focuses on training large language model (LLM) agents for collaborative reasoning tasks. The paper introduces Collaborative Agent Benchmark (ColBench), a new benchmark designed to evaluate multi-turn reinforcement learning (RL) algorithms in realistic artifact creation scenarios. The authors propose a novel RL algorithm named SWEET-RL (RL with Step-WisE Evaluation from Training-Time information) that uses a critic model with access to additional training data to provide step-level rewards, improving policy learning. Experimental results on ColBench demonstrate that SWEET-RL outperforms existing multi-turn RL methods, enabling smaller LLMs to achieve comparable performance to larger proprietary models in collaborative content creation.
