RAVEN: Real-time Autoregressive Video Extrapolation with Consistency-model GRPO
posted an update 16 days ago
Excited to share RAVEN, my first PhD project. Paper, code, and models are all released. RAVEN is for real-time autoregressive video generation. Instead of simply appending future chunks, we train the model to better remember and use its own generated history, leading to more realistic and natural long-horizon videos. Technically, RAVEN repacks self-rollouts into interleaved clean historical endpoints and noisy denoising states, aligning training-time attention with inference-time extrapolation. We also introduce CM-GRPO: by reformulating consistency-model sampling as a conditional Gaussian transition kernel, online RL can directly optimize the sampler transition used at inference.
