# OpenAI Unveils Sora: AI That Generates Minute-Long Videos by Learning How the World Works
OpenAI has announced Sora, a new AI model that can generate up to one minute of high-quality video from text descriptions. But the real breakthrough isn't just the video lengthâit's what the technology represents.
Unlike previous video generators, Sora was trained on massive amounts of video data at different lengths, resolutions, and aspect ratios. The model uses a transformer architecture that processes video as "spacetime patches," allowing it to understand how objects and scenes evolve over time.
What makes this significant is OpenAI's framing: they're calling these models "world simulators" rather than just video generators. By learning from vast amounts of video, Sora appears to develop an understanding of physics, object permanence, and how the real world behaves. This suggests the model isn't just stit
