MILES: Modular Instruction Memory with Learnable Selection for Self-Improving LLM Reasoning

arXiv:2607.06974v1 Announce Type: new Abstract: Large language models (LLMs) increasingly improve their reasoning at test time via additional computation, yet most existing works treat each problem in isolation. When problems arrive sequentially, accumulating reusable experience across them can further improve performance. Existing memory-based methods either store whole-solution templates that generalize poorly to novel problems or use heuristic step-level selection that is not optimized for final-answer correctness. Learning selection policies requires large-scale training data and fixed act

Why this matters
Why now

The paper introduces a novel modular instruction memory system (MILES) for LLMs, addressing current limitations in self-improvement and reasoning by learning to select relevant experiences. This occurs as the field of large language models rapidly advances towards more autonomous and efficient intelligent systems.

Why it’s important

This development could significantly enhance the reasoning capabilities and efficiency of LLMs over time, moving them closer to true self-improving agents. Strategic readers should note the potential for LLMs to generate more robust and contextually aware outputs without constant human oversight, impacting a wide range of applications.

What changes

LLMs can now leverage learned, reusable experience across sequential problems, leading to more generalized and accurate reasoning rather than isolated problem-solving or heuristic selection. This could fundamentally alter how LLMs operate and interact with complex, dynamic environments.

Direct

LLMs demonstrate improved performance on sequential reasoning tasks due to effective memory and selection mechanisms.

Second

The development accelerates the creation of more robust and autonomous AI agents capable of continuous learning and adaptation.

Third

This could lead to a ' Cambrian explosion' of specialized, self-improving AI agents that can rapidly master new domains with minimal human input, fundamentally changing white-collar work.
