Goal-VLA: Image-Generative VLMs As Object-Centric World Models Empowering Zero-Shot Robot Manipulation

ICRA 2026poster

Generalization remains a fundamental challenge in robotic manipulation. To tackle this challenge, recent Vision-Language-Action (VLA) models build policies on top of Vision-Language Models (VLMs), seeking to transfer their open-world semantic knowledge. However, their zero-shot capability lags signi…

SkillTrojan: Backdoor Attacks on Skill-Based Agent Systems

ICML 2026poster

Skill-based agent systems tackle complex tasks by composing reusable skills, improving modularity and scalability while introducing a largely unexamined security attack surface. We propose \textbf{SkillTrojan}, a backdoor attack that targets skill implementations rather than model parameters or trai…

Chinese SafetyQA: A Safety Short-form Factuality Benchmark for Large Language Models

ACL 2025long

With the rapid advancement of Large Language Models (LLMs), significant safety concerns have emerged. Fundamentally, the safety of large language models is closely linked to the accuracy, comprehensiveness, and clarity of their understanding of safety knowledge, particularly in domains such as law,…

Chinese SimpleQA: A Chinese Factuality Evaluation for Large Language Models

ACL 2025long

New LLM benchmarks are important to align with the rapid development of Large Language Models (LLMs). In this work, we present Chinese SimpleQA, the first comprehensive Chinese benchmark to evaluate the factuality ability of LLMs to answer short questions, and Chinese SimpleQA mainly has five proper…

PKU-SafeRLHF: Towards Multi-Level Safety Alignment for LLMs with Human Preference

ACL 2025long

In this work, we introduce the PKU-SafeRLHF dataset, designed to promote research on safety alignment in large language models (LLMs). As a sibling project to SafeRLHF and BeaverTails, we separate annotations of helpfulness and harmlessness for question-answering pairs, providing distinct perspectiv…
