Technical lineage: Maps Sora back to diffusion-transformer architectures, patchified video tokens, and large-scale joint text-video pretraining, synthesizing the publicly available technical signals.
Capabilities and applications: Catalogs the tasks Sora enables across filmmaking, education, and marketing, including long-duration generation, multi-shot continuity, and physics-plausible object interaction.
Limitations: Flags known failure modes - simulation artifacts, physical inconsistencies, object permanence errors - as well as safety concerns around misuse and bias.
Open directions: Identifies research problems such as efficient long-video training, grounded 3D/world modeling, and standardized evaluation for generative video.
