In an early Sora review, Brownlee questioned how OpenAI's video model was trained. Were his own videos used without his knowledge?

The first thing Brownlee mentions is object permanence. Sora has issues with displaying, say, a specific object in an individual's hand throughout the runtime of the video. Sometimes the object will move or just suddenly disappear. Just like with AI text, Sora's AI video suffers from hallucinations.

OpenAI has finally made Sora, its AI video generator, available to the public. You can try it today—if you can get through.
