InfoMem: Training Long-Context Memory Agents with Answer-Conditioned Information Gain

arXiv:2606.03329v1 Announce Type: new Abstract: Long-context tasks require LLMs to identify and preserve answer-relevant information from large contexts. Chunk-wise memory agents address this issue by sequentially reading document chunks, updating a compact memory, and generating the final answer from the accumulated memory. However, existing RL-based chunk-wise agents either rely on sparse final-answer rewards or use lexical intermediate rewards for memory and retrieval actions. These signals supervise task success or local overlap, but do not directly evaluate whether the final memory suppor

Why this matters
Why now

The paper addresses a current limitation in long-context AI agents, which is a significant research frontier in AI development.

Why it’s important

Improving how AI agents handle and synthesize information from large contexts is critical for their real-world applicability and their ability to perform complex tasks.

What changes

This new method offers a more effective approach to training memory agents, potentially leading to more reliable and capable AI systems in tasks requiring extensive information processing.
