Learning Modal-Mixed Chain-of-Thought Reasoning with Latent Embeddings

Yifei Shao, Kun Zhou, Ziming Xu +5

We study how to extend chain-of-thought (CoT) beyond language to better handle multimodal reasoning. While CoT helps LLMs and VLMs articulate intermediate steps, its text-only form…

Auto-scaling Continuous Memory for GUI Agent

Wenyi Wu, Kun Zhou, Ruoxin Yuan +4

We study how to endow GUI agents with scalable memory that help generalize across unfamiliar interfaces and long-horizon tasks. Prior GUI agents compress past trajectories into tex…

Vision-G1: Towards General Vision Language Reasoning with Multi-Domain Data Curation

Yuheng Zha, Kun Zhou, Yujia Wu +7

Despite their success, current training pipelines for reasoning VLMs focus on a limited range of tasks, such as mathematical and logical reasoning. As a result, these models face d…

Revisiting Reinforcement Learning for LLM Reasoning from A Cross-Domain Perspective

Zhoujun Cheng, Shibo Hao, Tianyang Liu +21

Reinforcement learning (RL) has emerged as a promising approach to improve large language model (LLM) reasoning, yet most open efforts focus narrowly on math and code, limiting our…

Activation Control for Efficiently Eliciting Long Chain-of-thought Ability of Language Models

Zekai Zhao, Qi Liu, Kun Zhou +4

Despite the remarkable reasoning performance, eliciting the long chain-of-thought (CoT) ability in large language models (LLMs) typically requires costly reinforcement learning or…

Decentralized Arena: Towards Democratic and Scalable Automatic Evaluation of Language Models

Yanbin Yin, Kun Zhou, Zhen Wang +11

The recent explosion of large language models (LLMs), each with its own general or specialized strengths, makes scalable, reliable benchmarking more urgent than ever. Standard prac…
