Summary
According to a post on X by @YangYou1991, an NUS researcher shared DiffusionART-Flash, a reinforcement learning method for diffusion models. It trains video and audio diffusion policies on just one or two high-noise timesteps, while rollouts still use the full trajectory. The snippet cites @Vanzllll as saying this means 25x fewer sample-timestep pairs on a 50-step schedule with similar reward gains. The team also reportedly open-sourced its MiniMax-H3 post-training recipe with six open reward models.

What happened
NUS's @YangYou1991 shared DiffusionART-Flash, which trains video and audio diffusion policies on just one or two high-noise timesteps while rollouts still use the full trajectory. @Vanzllll says that's 25x fewer sample-timestep pairs on a 50-step schedule with similar reward gains, and the team open-sourced its...
Why it matters
If the efficiency claims hold, teams training video or audio generators with reinforcement learning may need far fewer sampled timesteps to reach similar reward gains. The open-sourced MiniMax-H3 recipe and six open reward models would also let outside builders test the approach directly. Watch for independent benchmarks and the full paper or code, since the snippet is truncated and the 25x figure comes from a second post.
