This paper introduces HANDRAISER, a framework for interruptible communication in multi-agent LLM systems, addressing the issue of verbose and inefficient communication. The approach learns to predict optimal interruption points by balancing estimated future reward and communication cost. Experiments across text pictionary, meeting scheduling, and debate scenarios demonstrate a 32.2% reduction in communication cost with comparable or improved task performance, and generalization to new agents and tasks.
LLMs talk too much: HANDRAISER teaches agents to interrupt each other, slashing communication costs by 32% without sacrificing task performance.
Multi-agent systems using large language models (LLMs) have demonstrated impressive capabilities across various domains. However, current agent communication suffers from verbose output that overload context and increase computational costs. Although existing approaches focus on compressing the message from the speaker side, they struggle to adapt to different listeners and identify relevant information. An effective way in human communication is to allow the listener to interrupt and express their opinion or ask for clarification. Motivated by this, we propose an interruptible communication framework that allows the agent who is listening to interrupt the current speaker. Through prompting experiments, we find that current LLMs are often overconfident and interrupt before receiving enough information. Therefore, we propose a learning method that predicts the appropriate interruption points based on the estimated future reward and cost. We evaluate our framework across various multi-agent scenarios, including 2-agent text pictionary games, 3-agent meeting scheduling, and 3-agent debate. The results of the experiment show that our HANDRAISER can reduce the communication cost by 32.2% compared to the baseline with comparable or superior task performance. This learned interruption behavior can also be generalized to different agents and tasks.
