HyMem: Hybrid Memory Architecture for LLM Agents

ai-technology · 2026-05-04

Researchers propose HyMem, a hybrid memory architecture for large language model (LLM) agents that addresses inefficiencies in extended dialogues. Existing methods face a trade-off between efficiency and effectiveness: compression loses critical details, while raw text retention adds overhead. HyMem enables dynamic on-demand scheduling through multi-granular memory representations, inspired by cognitive economy. It adopts a dual-granular storage scheme with a dynamic two-tier retrieval mechanism. The paper is available on arXiv under identifier 2602.13933.
