PHYSIX OBSERVATION

Kling 4.0 raises native duration, HDR specs, and the reference asset limit all at once, showing that competition in video models has shifted from "can it generate" to "can it reliably deliver key shots." For professional production pipelines, spec upgrades are only the entry ticket; whether a model can embed itself into the collaboration chain between directors and teams is the real dividing line for the next stage.
