A key innovation is the Cascade Reinforcement Learning (Cascade RL) framework, which enhances reasoning through a two stage process: offline RL for stable convergence and online RL for refined alignment. This coarse to fine training strategy leads to substantial improvements on downstream reasoning tasks, e.g., MMMU and MathVista. To opt…
