Learning Query-Aware Budget-Tier Routing for Runtime Agent Memory

arXiv:2602.06025v2 Announce Type: replace-cross Abstract: Memory is increasingly central to Large Language Model (LLM) agents operating beyond a single context window, yet most existing systems rely on offline, query-agnostic memory construction that can be inefficient and may discard query-critical information. Although runtime memory utilization is a natural alternative, prior work often incurs substantial overhead and offers limited explicit control over the performance-cost trade-off. In this work, we present \textbf{BudgetMem}, a runtime agent memory framework for explicit, query-aware pe

Why this matters
Why now

The increasing complexity and practical deployment of LLM agents necessitate more efficient and adaptable memory management solutions to move beyond single-context window limitations.

Why it’s important

Improved runtime memory for AI agents directly addresses a critical bottleneck in deploying more capable and persistent AI systems, which can significantly enhance their autonomy and performance.

What changes

The explicit, query-aware control over performance-cost trade-offs in agent memory, offered by BudgetMem, changes how developers optimize and deploy advanced AI agents.
