Toward Efficient Agents: Memory, Tool learning, and Planning

arXiv:2601.14192v2 Announce Type: replace Abstract: Recent years have witnessed increasing interest in extending large language models into agentic systems. While the effectiveness of agents has continued to improve, efficiency, which is crucial for real-world deployment, has often been overlooked. This paper therefore investigates efficiency from three core components of agents: memory, tool learning, and planning, considering costs such as latency, tokens, steps, etc. Aimed at conducting comprehensive research addressing the efficiency of the agentic system itself, we review a broad range of

Why this matters
Why now

The accelerating advancement and deployment of large language models are pushing the boundaries of AI agent capabilities, making efficiency a critical and timely focus for real-world application.

Why it’s important

Efficiency in AI agents directly impacts their scalability, deployment costs, and practical utility, thereby accelerating the transition from experimental systems to pervasive, economically viable solutions.

What changes

The focus is shifting from pure capability demonstration to optimizing the practical and economic viability of AI agents through improved memory, tool learning, and planning efficiency.
