DeepPhy: Benchmarking Agentic VLMs on Physical Reasoning

AAAI 2026technical

Although Vision Language Models (VLMs) exhibit strong perceptual abilities and impressive visual reasoning, they struggle with attention to detail and precise action planning in complex, dynamic environments, leading to subpar performance. Real-world tasks typically require complex interactions, adv

See the World, Discover Knowledge: A Chinese Factuality Evaluation for Large Vision Language Models

ACL 2025finding

The evaluation of factual accuracy in large vision language models (LVLMs) has lagged behind their rapid development, making it challenging to fully reflect these models’ knowledge capacity and reliability. In this paper, we introduce the first factuality-based visual question-answering benchmark in…

Token Preference Optimization with Self-Calibrated Visual-Anchored Rewards for Hallucination Mitigation

EMNLP 2025

Direct Preference Optimization (DPO) has been demonstrated to be highly effective in mitigating hallucinations in Large Vision Language Models (LVLMs) by aligning their outputs more closely with human preferences. Despite the recent progress, existing methods suffer from two drawbacks: 1) Lack of sc
