Self-Assessment Reinforcement Learning for Search-State Awareness in Retrieval-Augmented Large Language Models

Read the original on arXiv Computation and Language →

The paper introduces Self-Assessment Reinforcement Learning (SARL), a framework that trains large language models to recognize their own search state during retrieval-augmented tasks. SARL uses a dual reward system to balance corrective assessment and efficiency, achieving significant performance gains over strong baselines on multi‑hop reasoning and deep research benchmarks. It also demonstrates improved training stability for longer search horizons, outperforming methods that rely on auxiliary supervision or multi‑agent coordination.

Harness-1: Reinforcement Learning for Search Agents with State-Externalizing Harnesses

arXiv:2606. 02373v1 Announce Type: new Abstract: Search agents are often trained as policies over growing transcripts: the model must decide how to search while also remembering what it has seen, which evidence is useful, which constraints remain open, and which claims have actually been checked.

To Answer or to Abstain: Mitigating Search-Agent Hallucinations via Abstention-Aware Reinforcement Learning

Recent advances in equipping Large Language Models (LLMs) with search tools and outcome-reward reinforcement learning (RL) have achieved new state-of-the-art results on open-domain QA tasks. However, we argue that current training paradigms harbor a critical vulnerability: they predominantly reward correct answers but fail to penalize fabricated ones when retrieval fails, thereby implicitly exacerbating hallucinations.
