Sora 2
OpenAI's Sora 2 is a groundbreaking AI video generation model that creates realistic, physics-aware videos with synchronized audio from text prompts.
Text-to-video generation with synchronized audio
Sora 2 is OpenAI's video generation model, announced on September 30, 2025. It generates videos up to 10 seconds long with 4K-like detail from text prompts, supporting visual styles including cinematic, photorealistic, and anime. The model integrates audio generation — dialogue, sound effects, and ambient sound — synchronized to on-screen action, including lip-synced character speech, which distinguishes it from its predecessor.
Sora 2 is designed for content creators, filmmakers, marketers, and storytellers who want to produce video content from text descriptions. It supports multi-shot scene control, allowing users to maintain character and world continuity across multiple shots within a single video with control over camera angles, lighting, and transitions. A Cameo feature lets users upload a short video of themselves to inject their likeness and voice into generated scenes.

Synchronized Audio
Produces integrated audio — including dialogue, sound effects, and ambient sound — automatically synced to on-screen action and character lip movements.
Physics-Aware Motion
Models real-world physics and object permanence to render complex motions such as gymnastics and athletic movements with consistent spatial accuracy.
Multi-Shot Scene Control
Follows multi-part prompts while maintaining character and world continuity across shots, with fine-grained control over camera angles, lighting, and transitions.
Cameo Likeness Injection
Accepts a short user-uploaded video to embed the user's face and voice into any AI-generated scene for personalized video storytelling.
Image-to-Video Input
