CPMöbius: Iterative Coach–Player Reasoning for Data-Free Reinforcement Learning

ICML 2026poster

Large Language Models (LLMs) have demonstrated strong potential in complex reasoning, yet their progress remains fundamentally constrained by reliance on massive high-quality human-curated tasks and labels, either through supervised fine-tuning (SFT) or reinforcement learning (RL) on reasoning-speci…

CubeBench: Diagnosing Interactive, Long-Horizon Physical Intelligence under Partial Observations

ICLR 2026poster

Large Language Model (LLM) agents, while proficient in the digital realm, face a significant gap in physical-world deployment due to the challenge of forming and maintaining a robust spatial mental model. We identify three core cognitive challenges hindering this transition: spatial reasoning, long-…

The Right Time Matters: Data Arrangement Affects Zero-Shot Generalization in Instruction Tuning

ACL 2025finding

Understanding alignment techniques begins with comprehending zero-shot generalization brought by instruction tuning, but little of the mechanism has been understood. Existing work has largely been confined to the task level, without considering that tasks are artificially defined and, to LLMs, merel…

Tell Me More! Towards Implicit User Intention Understanding of Language Model Driven Agents

ACL 2024long

Current language model-driven agents often lack mechanisms for effective user participation, which is crucial given the vagueness commonly found in user instructions. Although adept at devising strategies and performing tasks, these agents struggle with seeking clarification and grasping precise use…
