2026Reasoning agents increasingly rely on external tools such as web search to answer complex queries. Reinforcement learning (RL) fine-tuning algorithms such as GRPO have improved long-form reasoning in text-only language models, particularly for coding and mathematics. Reliable tool use in multimodal agents, however, remains challenging because models must interpret text and images while integrating noisy

ICRA 20262026We present the Generalized Action Model (GAM), a production-grade foundation model that unifies robotic action generation across diverse tasks and embodiments through a vision-language-action (VLA) pipeline. GAM addresses two fundamental barriers in scaling robotic manipulation: the lack of a unified representation for diverse robot end-effectors and the prohibitive cost of acquiring high-quality interaction

When rubrics fail: Error enumeration as reward in reference-free RL post-training for virtual try-on2026Reinforcement learning with verifiable rewards (RLVR) and Rubrics as Rewards (RaR) have driven strong gains in domains with clear correctness signals and even in subjective domains by synthesizing evaluation criteria from ideal reference answers. But many real-world tasks admit multiple valid outputs and lack the single ideal answer that rubric generation depends on. We identify this reference-free setting

QRS 20262026Test automation is moving from fixed script replay to agent driven execution and judgement. An agent may read a goal, inspect product state, call tools, recover from small changes, and collect evidence before reporting a result. Existing test case formats do not give enough structure for this style of execution. Plain prompts mix setup, purpose, rules, and steps. Traditional scripts are repeatable, but

ICML 2026 Workshop on Combining Theory and Benchmark2026Generative text classifiers, which assign labels by modeling the joint distribution over inputs and labels, have recently regained attention due to strong low-sample performance and a growing perception that they are less prone to shortcut learning than discriminative classifiers. However, existing evidence for shortcut avoidance is often indirect, frequently conflates classifier formulation with architectural
