OpenAI has released Sora 2, its newest video generation model, alongside a new iOS app called Sora. The company describes this upgrade as a major leap from early video generation, with a stronger grasp of physics, realism, and state consistency.
What Sora 2 adds
Sora 2 is designed to handle complex sequences without breaking the illusion of reality. It produces synchronized video and audio, including speech and sound effects. The model respects basic physical laws such as gravity, buoyancy, and momentum, and can depict realistic mistakes such as a basketball bouncing off the rim rather than magically teleporting.
Why it matters
Video models have been slower to develop compared to text-based systems. OpenAI positions Sora 2 as an important milestone toward building general world simulators: models that understand and operate in physical environments, which could support future AI agents and robotics.
How controllability shows up
The new system can follow detailed, multi-shot instructions while keeping objects and environments consistent across the sequence. Unlike earlier video models that distorted objects to satisfy a prompt, Sora 2’s errors resemble plausible mistakes by characters in a scene. Sora 2 does not just create visuals. It generates background sounds, dialogue, and effects aligned with what is happening on screen, giving outputs the feel of complete short films rather than silent clips.
Upload yourself and cameos
The app introduces a cameo feature, letting users record a short clip of themselves to appear in generated videos. The model can integrate likeness and voice into scenes with high accuracy. Control is left to the user, who can grant or revoke cameo access at any time. Sora is being launched as a social app centered on video creation and remixing. The feed prioritizes content from people you know and is framed around inspiring creativity rather than maximizing passive scrolling. Cameos are presented as the feature that makes the app feel new compared to existing platforms.
Safety and feed design
OpenAI has built tools for feed customization through natural language, wellbeing checks, and stronger protections for teens, including daily content limits and stricter cameo settings. Parental controls through ChatGPT allow adjustments such as disabling algorithmic personalization or managing direct messages. Human moderation teams are also expanding to handle harmful behavior.
Availability and pricing
The app is available now for iOS users in the U.S. and Canada, with more regions to follow. Sora 2 will be free at launch with limits tied to compute resources. ChatGPT Pro subscribers can access a higher quality Sora 2 Pro model on sora.com, with API access planned. The older Sora 1 Turbo remains online, and existing content is preserved.
The takeaway
Despite major advances, Sora 2 still produces errors and has not mastered all aspects of physical realism. OpenAI emphasizes that scaling up video training is still in early stages, but progress so far suggests the path forward is promising. Sora 2 combines more realistic video and audio generation with a social platform for creative use. Its advances in physics, consistency, and controllability position it as more than a novelty tool, pointing toward systems that simulate reality in ways useful for entertainment, communication, and eventually broader AI applications.
