Diffusion Language Models are Super Data Learners

Jinjie Ni, Qian Liu, Longxu Dou +5

Under strictly controlled pre-training settings, we observe a Crossover: when unique data is limited, diffusion language models (DLMs) consistently surpass autoregressive (AR) mode…

Training Optimal Large Diffusion Language Models

Jinjie Ni, Qian Liu, Chao Du +5

We introduce Quokka, the first systematic scaling law for diffusion language models (DLMs), encompassing both compute-constrained and data-constrained regimes, and studying the key…

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

Zijian Wu, Xiangyan Liu, Xinyuan Zhang +12

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-hea…

SynthRL: Scaling Visual Reasoning with Verifiable Data Synthesis

Zijian Wu, Jinjie Ni, Xiangyan Liu +3

Vision-language models (VLMs) trained via reinforcement learning with verifiable reward (RLVR) have shown notable progress in scaling test-time compute effectively. In this work, w…

Efficient Process Reward Model Training via Active Learning

Keyu Duan, Zichen Liu, Xin Mao +5

Process Reward Models (PRMs) provide step-level supervision to large language models (LLMs), but scaling up training data annotation remains challenging for both humans and LLMs. T…

NoisyRollout: Reinforcing Visual Reasoning with Data Augmentation

Xiangyan Liu, Jinjie Ni, Zijian Wu +5

Recent advances in reinforcement learning (RL) have strengthened the reasoning capabilities of vision-language models (VLMs). However, enhancing policy exploration to better scale…
