AutoRAS: Learning Robust Agentic Systems with Primitive Representations

Yang Yue, Xuancheng Zhu, Yuyang Ma +7

The automated design of agentic systems offers a promising pathway for scaling large language models (LLMs) beyond single-agent reasoning. While prior work has advanced task perfor…

LLMZero: Discovering Adaptive Training Strategies for RL Post-Training via LLM Agents

Haoyang Fang, Wei Zhu, Boran Han +11

RL post-training strategies are dataset-dependent and reveal a recurring empirical pattern: capacity parameters accumulate monotonically across stages, while regularization paramet…

See First, Answer Later: Visual Evidence Pre-Alignment via Sufficiency-Driven RL

Yilian Liu, Sicong Leng, Guoshun Nan +7

Multimodal large language models (MLLMs) integrate strong text reasoning with visual inputs, yet their responses can be inconsistent with the underlying images, indicating ineffect…

ReSkill: Reconciling Skill Creation with Policy Optimization in Agentic RL

Zelin He, Haotian Lin, Boran Han +6

Agentic reinforcement learning (RL) enables LLM agents to improve continuously from environment rewards, yet the resulting policies do not systematically accumulate reusable strate…

Can LLM Agents Sustain Long-Horizon Organizational Dynamics?

Xuancheng Zhu, Yang Yue, Shuaibing Wan +4

Large language agents are increasingly used for social simulation, yet it remains unclear whether they can sustain coherent behavior in structured organizations, where goals must p…
