Sora (OpenAI)

Sora's output quality is genuinely impressive in isolated demos — the physics simulation and cinematic coherence represent a step change from earlier AI video tools. The December 2024 public release, however, surfaced a gap between the viral demo clips and typical user output: getting Sora to produce the quality seen in marketing demos requires significant prompt engineering, and the generation system is rate-limited enough that iterating toward a good result is slow.
