MemRefine: LLM-Guided Compression for Long-Term Agent Memory

arXiv:2606.13177v1 Announce Type: new Abstract: Large language model (LLM) agents are increasingly expected to operate over long-term interactions, where information from past dialogues must be preserved and recalled to support future tasks. However, as interactions accumulate, the memory store grows without bound and fills with redundant entries that inflate storage cost and degrade retrieval by crowding out the most useful evidence. Furthermore, this is especially limiting on resource-constrained platforms with hard memory budgets, motivating us to formulate storage-budgeted memory managemen

Why this matters
Why now

The increasing complexity and expected longevity of LLM agent interactions necessitate more efficient memory management to overcome current technological and resource limitations.

Why it’s important

Efficient long-term memory for AI agents is critical for scaling their capabilities, enabling more complex tasks, and reducing operational costs, directly impacting their commercial viability and deployment.

What changes

The ability to compress and refine agent memory intelligently will allow for more sophisticated and enduring AI agents, particularly in resource-constrained environments, shifting the frontier of what agents can achieve.
