ReSum: Synergizing LLM Reasoning and Summarization with Reinforcement Learning

arXiv:2606.13316v1 Announce Type: new Abstract: Reinforcement Learning with Verifiable Rewards (RLVR) is a central technique for improving long-horizon reasoning in Large Language Models (LLMs). However, existing RLVR methods often encourage unnecessarily long reasoning rollouts, which can degrade reasoning coherence and exhaust the available context budget. Existing approaches to long-context organization often depend on external mechanisms to organize rollouts, rather than enabling the model to manage its own reasoning trajectory. To address this limitation, we propose ReSum, a novel RLVR fr

Why this matters
Why now

The increasing complexity and length of AI reasoning tasks necessitate more efficient and coherent management of LLM operations, especially as context windows expand.

Why it’s important

Improving LLM reasoning coherence and efficiency directly impacts the practical utility and scalability of AI agents, making their deployment more feasible and reliable.

What changes

This research outlines a method for LLMs to self-manage reasoning trajectories, reducing reliance on external mechanisms and potentially unlocking more sophisticated agentic behaviors.
