Planner-Centric Reinforcement Learning for Deep Research with Structure-Aware Reward

arXiv:2605.30824v1 Announce Type: new Abstract: Deep research tasks require LLMs to plan what to investigate, retrieve evidence, and synthesize long-form answers across multiple branches of inquiry. Existing training paradigms either rely on short-form verifiable QA as a proxy or optimize monolithic long trajectories, which makes planning and execution difficult to disentangle and yields weak credit assignment for the planning process. We propose DecomposeR, a planner-centric deep research framework that represents research plans as typed directed acyclic graphs (DAGs), allowing planning to be

Why this matters
Why now

The increasing complexity of AI tasks demands more sophisticated planning and research capabilities from LLMs, moving beyond simple QA.

Why it’s important

This development enhances the autonomy and analytical depth of AI, potentially accelerating research and development across numerous fields.

What changes

AI systems can now engage in more structured and multi-branch inquiry, improving their ability to conduct deep research and synthesize long-form answers.
