Large language models (LLMs), including ChatGPT, Bard, and Llama, have achieved remarkable successes over the last two years in a range of different applications. In spite of these successes, there exist concerns that limit the wide application of LLMs. A key problem is the problem of hallucination. Hallucination refers to the fact that in addition to correct responses, LLMs can also generate seemingly correct but factually incorrect responses. This report aims to present a comprehensive review of the current literature on both hallucination detection and hallucination mitigation. We hope that this report can serve as a good reference for both engineers and researchers who are interested in LLMs and applying them to real world tasks.

  1. HIVE: Understanding Post-Hallucination Reasoning in Vision Language Models

    cs.CV 2026-07 conditional novelty 7.0

    Hallucinated captions systematically improve VLM accuracy on vision-language tasks across nine models and nine datasets, with gains linked to broadened semantic coverage and modulated reasoning entropy.

  2. Structure Guided Retrieval-Augmented Generation for Factual Queries

    cs.IR 2026-04 unverdicted novelty 7.0

    SG-RAG frames retrieval as subgraph matching to ensure LLMs meet every condition in factual queries and reports large gains over baselines on a new 120k-pair ERQA dataset.

  3. Hallucination is Inevitable: An Innate Limitation of Large Language Models

    cs.CL 2024-01 conditional novelty 7.0

    Hallucinations are inevitable in LLMs because they cannot learn all computable functions according to learning theory.
