AB  - OpenAI's Sora technical report, published in February 2024, describes a diffusion transformer model that generates high-definition video up to one minute long by treating video clips as sequences of spacetime patches. The report documents emergent properties in Sora's outputs, including 3D consistency, object permanence, and plausible physical interactions, that were not the subject of explicit supervision. The February 2024 release had an immediate and measurable effect on discourse in the animation and visual-effects fields, resetting expectations about the near-term capability ceiling for text-to-video generation.
