Perception-Aware Policy Optimization for Multimodal Reasoning

ICLR 2026poster

Reinforcement Learning with Verifiable Rewards (RLVR) has proven to be a highly effective strategy for empowering Large Language Models (LLMs) with long chain-of-thought reasoning abilities. However, its design and optimizations remain tailored to purely textual domains, resulting in suboptimal perf…

When to Think, When to Speak: Learning Disclosure Policies for Large Language Model Reasoning

ICML 2026poster

Standard Chain-of-Thought (CoT) reasoning trades reliability for responsiveness: in a single user-visible token stream, more deliberation delays meaningful output, imposing a ``silence tax.'' We introduce \emph{Side-by-Side (SxS) Interleaved Reasoning}, a training framework that makes \emph{disclosu…

SyncMind: Measuring Agent Out-of-Sync Recovery in Collaborative Software Engineering

ICML 2025poster

Software engineering (SE) is increasingly collaborative, with developers working together on shared complex codebases. Effective collaboration in shared environments requires participants---whether humans or AI agents---to stay on the same page as their environment evolves. When a collaborator's und…
