Fostering Video Reasoning via Next-Event Prediction

ICLR 2026poster

Next-token prediction serves as the foundational learning task that enables reasoning in LLMs. But what should the learning task be when aiming to equip MLLMs with temporal reasoning capabilities over video inputs? Existing tasks such as video captioning primarily promote modality alignment, while v…

MCPMark: A Benchmark for Stress-Testing Realistic and Comprehensive MCP Use

ICLR 2026poster

The MCP standardizes how LLMs interact with external systems, forming the foundation for general agents. However, existing MCP benchmarks remain narrow in scope: they focus on read-heavy tasks or tasks with limited interaction depth, and fail to capture the complexity and realism of real-world workf…

CodexGraph: Bridging Large Language Models and Code Repositories via Code Graph Databases

NAACL 2025long

Large Language Models (LLMs) excel in stand-alone code tasks like HumanEval and MBPP, but struggle with handling entire code repositories. This challenge has prompted research on enhancing LLM-codebase interaction at a repository scale. Current solutions rely on similarity-based retrieval or manual…

NoisyRollout: Reinforcing Visual Reasoning with Data Augmentation

NeurIPS 2025poster

Recent advances in reinforcement learning (RL) have strengthened the reasoning capabilities of vision-language models (VLMs). However, enhancing policy exploration to better scale test-time compute remains largely underexplored. In addition, VLMs continue to struggle with imperfect visual perception…
