Researchers have developed a new method called BRACE (Bank-calibrated Rollout Allocation under Correlated Episodes) to optimize the training of tool-using language models, specifically within Model Context Protocol (MCP) environments. This approach uses reward disagreement to guide the evaluation and allocation of rollouts for policy training, aiming to improve learning signals. Experiments with Qwen3-VL models at various scales demonstrated that BRACE achieved higher peaks with fewer training rollouts compared to existing baselines, and also showed strong performance on BFCL and NESTFUL tasks.
