Peer memory in LLM agents alters consultation without improving accuracy

By PulseAugur Editorial · [1 sources] ·

A new study introduces PeerMem, a system designed to enhance multi-agent LLM interactions by allowing agents to retain and reuse information from past consultations. The research explored how this 'peer memory' affects agent consultation patterns and answer accuracy using models like Qwen3-32B and Gemma-4-31B-it on the HotpotQA dataset. While warm memory demonstrated a reduction in regret and an increase in consulting other agents, the study found no significant improvement in final answer accuracy, suggesting that memory primarily influences the consultation process rather than the outcome.

    Peer Memory Changes Who LLM Agents Consult Without a Detected Gain in Answer Accuracy

    Multi-agent LLM systems often reuse the same agents across tasks, creating an opportunity to draw on past interactions when deciding whom to consult. We study this form of memory with PeerMem, which saves MACE's LinUCB state and reuses it when the same agents return. Using six ag…
