Sora 2 – OpenAI’s Next-Generation AI Model for Audio and Video Generation

What is Sora 2?

Sora 2 is OpenAI’s next-generation AI model for audio and video generation. It introduces significant upgrades and improvements across multiple dimensions, enabling the creation of videos that better adhere to the laws of physics. For example, when simulating complex action scenes such as gymnastics or paddleboard balancing, the movements of objects and people appear more natural and realistic.

For the first time, Sora 2 supports AI audio generation synchronized with visuals, producing dialogues, sound effects, and complete soundscapes that match the video content. Users gain more refined control over generated videos, including camera switching and scene configuration, while maintaining logical consistency within the virtual world. Sora 2 can also generate videos in a wide range of styles, such as Studio Ghibli-inspired animation, catering to diverse creative needs.

Key Features of Sora 2

More Realistic Physics Simulation: Generates videos that follow physical laws, with natural and realistic object and character trajectories in complex action scenarios.
Audio-Visual Synchronization: For the first time, supports AI audio generation aligned with visuals, producing synchronized dialogues, effects, and immersive soundscapes.
Enhanced Controllability: Users can finely control aspects such as camera angles and scene settings while preserving the overall logic of the virtual world.
Broader Style Range: Supports generating videos in multiple styles (e.g., Ghibli-style), meeting different creative preferences.
Content Creation Support: Provides creators with powerful tools to generate high-quality videos from simple text prompts, applicable to education, advertising, film, and more.
Cameo Function: Users can insert real people, pets, or objects into AI-generated scenes, with strict permissions and privacy settings. Users retain full end-to-end control over their cameo, deciding who can use it, and can revoke or delete cameo content anytime.
Remix Function: Allows users to remix existing videos. By clicking the Remix button, entering new prompts, and building upon an existing video, users can easily participate in trends and shared storylines.
Social Platform Integration: OpenAI launched the Sora app, where users can create, remix, and cameo in AI-generated videos—essentially an AI-powered version of TikTok.
