HALDETECT system tackles multimodal model hallucinations at ImageEval 2026

By PulseAugur Editorial · [1 sources] ·

Researchers have developed HALDETECT, a system designed to identify and mitigate hallucinations in large multimodal models. Their approach frames the problem as a contrastive decision, prioritizing the answer before its explanation and structuring reasoning around visual elements and context. The system, which fine-tuned Qwen2.5-VL-7B-Instruct using 4-bit QLoRA, achieved third place in the ImageEval 2026 hallucination-detection task, demonstrating that adaptation methods can outperform simple prompting.

    HALDETECT at ImageEval 2026 Shared Tasks: Answer-First Contrastive Grounding with QLoRA

    arXiv:2609.11236v1 Announce Type: new Abstract: Large multimodal models tend to hallucinate visual detail fluently, which limits their deployment for fine-grained interpretation. We present HALDETECT, our system for the English hallucination-detection track (Task 1b) of ImageEval…
