arXiv:2609. 04875v1 Announce Type: cross Abstract: Long-running LLM agents are stateful: beyond the transcript they accrete compressed summaries, plaintext memory, pending tool plans, and, under every serving API, a KV cache.

MemMA is a plug‑and‑play multi‑agent framework that coordinates the memory cycle of memory‑augmented LLM agents on both forward and backward paths. On the forward path, a Meta‑Thinker guides a Memory Manager for construction and a Query Reasoner for iterative retrieval. On the backward path, MemMA performs in‑situ self‑evolving memory construction, generating probe QA pairs, verifying the memory, and converting failures into repair actions before finalization. Experiments on LoCoMo show that MemMA consistently outperforms existing baselines across multiple LLM backbones and improves three different storage backends.

AdaMem introduces adaptive memory policies that allow personalized agents to decide what information to write into long‑term memory based on user preferences for each interaction context. Each policy is updated from periodic feedback and controls subsequent memory writing, aiming to improve relevance and reduce unnecessary memory persistence. In experiments on AdaMem‑Bench, AdaMem raises QA accuracy from 80.0% to 84.35% while cutting persistent memory by 9.27%, though models still struggle to execute policies reliably.

The paper introduces DiscernMem, a training‑free framework for improving memory quality and usage in LLM‑based multi‑agent systems. It combines Defect‑Aware Memory Refinement (DMR), which diagnoses and repairs flawed memories, with Boundary‑Learning Meta‑Memory (BLM), which learns when to apply or avoid each memory based on context. Experiments with Qwen3‑4B‑Instruct‑2507 on four benchmarks show DiscernMem outperforms existing baselines, achieving higher scores on AutoGen, CAMEL, and MacNet, and improving code generation and symbolic planning performance.
