Dynamic Rollout Editing for Reducing Overthinking in RL-Trained Reasoning Models

Zihao Wei, Wenjie Shi, Liang Pang +8

Long-form chain-of-thought reasoning can improve LLM performance on complex tasks, but models often continue generating unnecessary reasoning after a correct answer has emerged. We…

Latent-GRPO: Group Relative Policy Optimization for Latent Reasoning

Jingcheng Deng, Zihao Wei, Liang Pang +4

Latent reasoning offers a more efficient alternative to explicit reasoning by compressing intermediate reasoning into continuous representations and substantially shortening reason…

SkillAttack: Automated Red Teaming of Agent Skills through Attack Path Refinement

Zenghao Duan, Yuxin Tian, Zhiyi Yin +6

LLM-based agent systems increasingly rely on agent skills sourced from open registries to extend their capabilities, yet the openness of such ecosystems makes skills difficult to t…

from Benign import Toxic: Jailbreaking the Language Model via Adversarial Metaphors

Yu Yan, Sheng Sun, Zenghao Duan +5

Current studies have exposed the risk of Large Language Models (LLMs) generating harmful content by jailbreak attacks. However, they overlook that the direct generation of harmful…

LLM Latent Reasoning as Chain of Superposition

Jingcheng Deng, Liang Pang, Zihao Wei +6

Latent reasoning offers a computation-efficient alternative to Chain-of-Thought but often suffers from performance degradation due to distributional misalignment and ambiguous chai…

The Evolution of Thought: Tracking LLM Overthinking via Reasoning Dynamics Analysis

Zihao Wei, Liang Pang, Jiahao Liu +7

Test-time scaling via explicit reasoning trajectories significantly boosts large language model (LLM) performance but often triggers overthinking. To explore this, we analyze reaso…
