Adaptive Co-Serving LLM Watermarking on Modern Inference Engines

Kieu Dang, Phung Lai, Ching-Yun Ko +1

Large language model (LLM) watermarking is important for ownership verification and intellectual property protection. However, existing approaches focus on algorithmic design while…

EvoFlux: Inference-Time Evolution of Executable Tool Workflows for Compact Agents

Kushal Raj Bhandari, Ling Yue, Ching-Yun Ko +4

Small language models (1.5B-4B parameters) offer low-cost, low-latency tool use but often produce plausible plans that fail during execution due to unavailable tools, missing argum…

From Static Templates to Dynamic Runtime Graphs: A Survey of Workflow Optimization for LLM Agents

Ling Yue, Kushal Raj Bhandari, Ching-Yun Ko +6

Large language model (LLM)-based systems are becoming increasingly popular for solving tasks by constructing executable workflows that interleave LLM calls, information retrieval,…

Steering Externalities: Benign Activation Steering Unintentionally Increases Jailbreak Risk for Large Language Models

Chen Xiong, Zhiyuan He, Pin-Yu Chen +2

Activation steering is a practical post-training model alignment technique to enhance the utility of Large Language Models (LLMs). Prior to deploying a model as a service, develope…

Learning Rate Matters: Vanilla LoRA May Suffice for LLM Fine-tuning

Yu-Ang Lee, Ching-Yun Ko, Pin-Yu Chen +1

Low-Rank Adaptation (LoRA) is the prevailing approach for efficient large language model (LLM) fine-tuning. Building on this paradigm, recent studies have proposed alternative init…
