SARL trains search models to track missing retrieved information
Original title: Self-Assessment Reinforcement Learning for Search-State Awareness in Retrieval-Augmented Large Language Models
Authors report a 24.3% relative gain over the strongest baseline, with no extra assessment at test time.
Self-Assessment Reinforcement Learning (SARL) trains retrieval-augmented language models to recognize what information has been found and what is still missing. A dual reward captures the corrective effect of each self-assessment while penalizing overuse, so the model improves search without extra assessment at inference. Authors say it beats methods that use auxiliary supervision or multi-agent coordination and stays stable on longer search horizons.
Unconfirmed: Benchmark gains are the authors’ reported figures and are not independently confirmed.
- The method is a standalone RL framework with no inference-time scaffolding.
- Average gains cited are 35.9% on multi-hop reasoning and 27.9% on deep research.
- The dual reward penalizes excessive reliance on self-assessment.
- Authors say existing methods degrade when search horizons are extended.

Recent advances in search agents have enabled large language models to tackle complex tasks by retrieving and synthesizing external information. However, existing search agents often lack search-state awareness, i. e.
