Why choose between autoregressive (fast, streaming) and bidirectional (high-quality) video diffusion when a single model can do both even better? Excited to share Flex-Forcing, accepted as spotlight at #ICML2026! 📍Say hi to Chao Liu at our poster: July 9 | 2:30 - 4:15 PM KST | Hall A #3909... show more

At test time, Flex-Forcing allows you to dynamically change the chunk-size over frames and diffusion time-steps. 1⃣Bidirectional: Maximal context for global coherence 2⃣Autoregressive: Causal generation for fast streaming 3⃣Hybrid: Optimal tradeoff in terms of inference speed and quality

What does this mean in practice? 1⃣Better speed-quality tradeoff: Outperforms baselines in terms of both FPS and VBench score. 2⃣Coherent long video generation: Maintains stability over time while preserving a higher dynamic degree than baselines. 3⃣Any-order, any-timestep editing: Edit arbitrary video segments without triggering cascading errors in later frames.
