 ### Key Points
 
 - **Selective trajectory recording**: `trajectory_indices` controls which denoising steps are stored. For GRPO, only steps corresponding to `train_timesteps` are kept to reduce memory.
-- **SDE dynamics for exploration**: GRPO injects noise during sampling via SDE formulation, enabling the log-probability computation required for policy gradients. NFT, AWM, and DGPO use decoupled sampling (typically ODE) with `compute_log_prob=False`.
