Harmony Harness: Multi-Objective Self-Evolution of Agent Harnesses

Weichen Yu, Lesly Miculicich, Bhavana Dalvi Mishra +5

Recent work on self-evolving LLM agents treats the agent harness as an optimization target that can be iteratively improved through execution feedback. Existing approaches, however…

Steal the Patch Size: Adversarially Manipulate Vision-Language Models

Kai Hu, Akash Bharadwaj, Weichen Yu +1

We present a black-box model-stealing attack that recovers private vision-tokenizer configurations of deployed vision-language models (VLMs), including the visual patch size and in…

Multi-Rollout On-Policy Distillation via Peer Successes and Failures

Weichen Yu, Xiaomin Li, Yizhou Zhao +8

Large language models are often post-trained with sparse verifier rewards, which indicate whether a sampled trajectory succeeds but provide limited guidance about where reasoning s…

SecCodePRM: A Process Reward Model for Code Security

Weichen Yu, Ravi Mangal, Yinyi Luo +4

Large Language Models are rapidly becoming core components of modern software development workflows, yet ensuring code security remains challenging. Existing vulnerability detectio…

Vision Wormhole: Latent-Space Communication in Heterogeneous Multi-Agent Systems

Xiaoze Liu, Ruowang Zhang, Weichen Yu +7

Heterogeneous multi-agent systems combine models with different capabilities through a common communication interface. Exchanging internal states directly requires translating betw…

AgentArk: Distilling Multi-Agent Intelligence into a Single LLM Agent

Yinyi Luo, Yiqiao Jin, Weichen Yu +6

While large language model (LLM) multi-agent systems achieve superior reasoning performance through iterative debate, practical deployment is limited by their high computational co…

PrivCode: When Code Generation Meets Differential Privacy

Zheng Liu, Chen Gong, Terry Yue Zhuo +4

Large language models (LLMs) have presented outstanding performance in code generation and completion. However, fine-tuning these models on private datasets can raise privacy and p…

When the Same Coefficients Reach Different Places: Asymmetric Realizability in Transplanting Tokenizers across Large Language Models

Xiaoze Liu, Weichen Yu, Matt Fredrikson +2

Tokenizer transplant in cross-vocabulary model composition reconstructs donor-only embedding rows as weighted combinations over shared lexical anchors and reuses those coefficients…
