LeanGRPO: Eliminating Redundant Recomputation in Diffusion RL

LeanGRPO is presented by restructuring the data-parallel layout and introducing two recompute-free training schedules for trajectory-logprob diffusion RL, which achieves up to 1.83x end-to-end speedup while preserving the original optimization objective.

Bidirectional Resource Scheduling for Disaggregated and Asynchronous RL Post-Training

BiDiRL, a hybrid time-space multiplexing architecture for asynchronous, disaggregated RL designed to reduce resource idleness, is presented, including a hot-switch runtime that enables rapid switching between rollout and training resources with negligible overhead and a static, scheduling-aware planner based on time-pe...
