AgentCollab introduces a self-evaluation-driven collaboration paradigm for large language model agents, dynamically coordinating models of varying reasoning capacities during task execution. By using the agent’s own self-reflection to decide when to elevate to a stronger model, it avoids reliance on external routing modules and allocates additional reasoning budget only when recent failures indicate difficulty. Experiments on multi-step agent benchmarks demonstrate that this two-level small-large model setup consistently improves the accuracy-efficiency Pareto frontier of LLM agents.

Reasoning in language allows foundation models to spend more test-time compute on hard problems, such as those requiring decomposition, constraint tracking, and prediction of future consequences. Whet...
The paper introduces $R^3$, a post‑training method that converts vision‑language models into robotic reasoners by first mid‑training on expert reasoning traces and then refining them with single‑step rubric‑based reinforcement learning. $R^3$ enables free‑form language reasoning to guide low‑level manipulation policies, improving exploration, generalization, and performance on long‑horizon tasks in Language Table and simulated bimanual grocery packing benchmarks. The approach outperforms instruction‑only imitation learning baselines and demonstrates that natural language reasoning can serve as a test‑time compute mechanism for steering robotic actions.
