What is Sora 2? The Complete Guide to OpenAI's Video AI
A deep dive into Sora 2 — OpenAI's video generation model. How it works, what makes it different, and how to use it for your projects.
What is Sora 2?
Sora 2 is OpenAI's second-generation video generation model, released in late 2025. It marked a major leap forward in AI video quality, controllability, and length.
Key Improvements Over Sora 1
- Higher fidelity: 1080p resolution with photorealistic detail
- Longer clips: Up to 12 seconds (vs 5-6s in the original)
- Better physics: Realistic motion, gravity, object permanence
- Audio generation: Native synchronized sound effects
- Image-to-video: First-class support for animating still images
How Sora 2 Works
Sora 2 uses a diffusion transformer architecture — a combination of:
- Diffusion models (iterative denoising for high quality)
- Transformer blocks (for handling long video sequences)
The model treats video as a sequence of "spacetime patches" — a 3D grid of tokens representing space and time — and learns to predict the next frame.
