Sora 2 is OpenAI's second-generation text-to-video model, producing 1080p clips of up to 20 seconds with high physical realism, consistent lighting, and coherent object permanence. Access is bundled into ChatGPT Plus and Pro subscriptions. It is designed for creators and filmmakers who want high-quality video from natural language, within OpenAI's content policy constraints.

Features

Text-to-video up to 20 seconds at 1080p
Image-to-video with subject animation

+3 more

Pros

Physical realism — fluid dynamics, object permanence, and lighting consistency are best-in-class
ChatGPT integration enables video generation directly from a chat session without switching tools
Storyboard mode can generate a coherent multi-scene narrative from a single paragraph description
20-second clip length beats Runway, Luma, and Kling on single-generation length

Cons

Only available inside ChatGPT Plus ($20/mo) or Pro ($200/mo) — no standalone plan
Plus subscribers get 50 priority generations/month; heavy use exhausts this quickly
Content policy is more restrictive than competitors — certain creative scenarios are refused
No API access — cannot be integrated into automated pipelines
Output cannot be downloaded as separate project files — only MP4 export
