Ex-Omni-2D: Expressive Omni-Modal Dialogue Models with Native Visual Presence

Haoyu Zhang, Zhipeng Li, Xiaoying Tang +2

Omni-modal dialogue models can understand multimodal inputs and synthesize spoken replies, yet their responses remain visually disembodied. We introduce \textbf{Ex-Omni-2D}, an omn…

ADIAS: Automated Design of Interactive Agentic Systems

Lekang Jiang, Bohan Tang, Stephan Goetz +1

Automated agent design improves agent harnesses through iterative revision, evaluation, and feedback summarization. Existing methods are largely candidate-centric: cross-round expe…

Progressive Agent Skill Generation via Reinforcement Learning

Junhao Shen, Zhanqiu Zhang, Yiwen Guo +1

Existing skill generation methods largely rely on heuristics or pipeline-style consolidation, which must be specially designed for different evidence sources. In contrast, learning…

Many Voices, One Reward: Multi-Role Rubric Generation for LLM Judging and Reward Modeling

Dazhi Fu, Jiuding Yang, Yiwen Guo +1

Reliable reward and preference signals are critical for evaluating and optimizing large language models on open-ended tasks. Rubric-based judges offer a transparent way to decompos…

Ex-Omni: Enabling 3D Facial Animation Generation for Omni-modal Large Language Models

Haoyu Zhang, Zhipeng Li, Yiwen Guo +1

Omni-modal large language models (OLLMs) aim to unify multimodal understanding and generation, yet extending them to jointly produce speech and 3D facial animation remains largely…

MemoryForge: Synthesize Lifelong Memory for Human-Like LLM Agents

Bohan Tang, Yiwen Guo

Equipping Large Language Models (LLMs) with human-like personas is crucial for agentic applications, such as role-play and user simulation. Traditional prompt-based methods rely on…
