SWE-Router: Routing in Multi-turn Agentic Software Engineering Tasks

Seongho Son, Sangwoong Yoon, Jiahua Tang +3

Large language models (LLMs) embedded in multi-turn agentic harnesses are reshaping software engineering (SWE), but routing every task to a frontier model is wasteful when many iss…

Focus Matters: Phase-Aware Suppression for Hallucination in Vision-Language Models

Sohyeon Kim, Sang Yeon Yoon, Kyeongbo Kong

Large Vision-Language Models (LVLMs) have achieved impressive progress in multimodal reasoning, yet they remain prone to object hallucinations, generating descriptions of objects t…

wd1: Weighted Policy Optimization for Reasoning in Diffusion Language Models

Xiaohang Tang, Rares Dolga, Sangwoong Yoon +1

Improving the reasoning capabilities of diffusion-based large language models (dLLMs) through reinforcement learning (RL) remains an open problem. The intractability of dLLMs likel…

Robust Multi-Objective Controlled Decoding of Large Language Models

Seongho Son, William Bankes, Sangwoong Yoon +3

We introduce Robust Multi-Objective Decoding (RMOD), a novel inference-time algorithm that robustly aligns Large Language Models (LLMs) to multiple human objectives (e.g., instruct…
