arXiv:2606.29377v1 Announce Type: new Abstract: Retrieval-Augmented Generation (RAG) improves the factuality of large language models by grounding responses in external evidence, yet real-world deployments remain fragile. Failures often stem from missing or weakly relevant evidence, as well as from generation that does not faithfully reflect the retrieved context. Many existing approaches rely on fine-tuning, privileged access to internal model signals, or resource-insensitive escalation strategies, which limits their practicality in black-box and budget-constrained settings. We propose D2R-RA
The proliferation of RAG systems in real-world applications has highlighted their existing fragility and factual error rates, necessitating more practical and budget-conscious repair mechanisms.
Improving factual accuracy and reliability of RAG systems under realistic constraints is critical for their wider adoption, trust, and effective integration into enterprise and consumer applications.
New methods for diagnosing and repairing factual errors in RAG, capable of operating in black-box and budget-constrained environments, will enhance the robustness of AI applications without requiring expensive fine-tuning or privileged access.
