What the table does not settle
Two general-purpose AI companies' video models, both API-first, both documenting all three modes with native audio. Google states a 4K ceiling and a ten-second maximum for Gemini Omni Flash [1]; xAI states native 1080p and fifteen seconds for Grok Imagine Video 1.5, and publishes no release date on the documentation page [2].
These are the models most likely to be used casually — inside a chat app, in the middle of another task — which makes them unusually relevant to a preference vote. The question is not which has the higher ceiling but which one produces a clip you would keep on the first try, and that is a question only voters can answer.
