FlowCTS: On-policy Continuous Trajectory Supervision of Flow Models

arXiv:2607. 24522v1 Announce Type: new Abstract: While on-policy distillation (OPD) effectively addresses sparse rewards and exposure bias in large language model post-training, its extension to flow models remains underexplored.

DreOPD: Degraded-Reference Extrapolative On-Policy Distillation for Flow-matching Models

arXiv:2608. 09233v1 Announce Type: new Abstract: Flow-matching models are now a mainstream method to image generation, but its adaptation to diverse downstream scenarios typically relies on post-training, which may cause conflicts among task-specific optimization objectives.

Accelerating Visual On-Policy Distillation with Batched Speculative Jacobi Rollouts

The paper introduces HB‑SJD, a batched Speculative Jacobi Decoding backend that accelerates visual on‑policy distillation (OPD) by allowing images to advance independently and processing multiple tokens in parallel without a draft model. HB‑SJD switches between Full and Compact execution as images finish, reducing rollout and overall training time while maintaining generation quality. Experiments with LlamaGen demonstrate significant speedups without altering the teacher, distillation objective, or optimization procedure.

RL-Native Distillation: Exploiting Scored Trajectories for Few-Step Image Generation

Efficient text-to-image generation requires both reinforcement-learning (RL)-based reward alignment and few-step distillation, yet these procedures are typically performed sequentially, increasing training cost and risking the loss of reward gains during compression. We instead take an RL-native perspective: diffusion RL already generates reward-scored finite-step trajectories, whose intermediate states provide a natural source of distillation supervision rather than a disposable byproduct of sampling.
