Key Takeaway
Sora 2 is designed to produce video outcomes that adhere to established physics, contrasting with previous models that often distort reality. For instance, if a basketball player misses a shot, the ball will realistically rebound off the backboard instead of teleporting. The system maintains consistency across multiple shots and supports various visual styles, including photorealistic and anime. It can also generate audio elements like soundscapes and dialogue. A new feature allows users to embed recordings of people into generated environments, accurately portraying their appearance and voice. Currently, Sora 2 is accessible via an invite-only iOS app.
In contrast, Sora 2 is designed to produce outcomes that align more closely with established physics principles.
“Previous video models tend to be overly optimistic—they morph objects and distort reality to fulfill a text prompt,” the team explains.
“For instance, if a basketball player misses a shot, the ball might unexpectedly teleport to the hoop.
“In Sora 2, if a basketball player misses a shot, the ball will bounce off the backboard.”
The system can follow instructions across multiple shots while maintaining consistency of elements within the generated scenes.
It accommodates a variety of visual styles, ranging from photorealistic and cinematic to anime.
In addition to video content, the model can also generate audio components such as background soundscapes, dialogue, and sound effects.
OpenAI has introduced a new feature that allows users to embed recordings of people or objects directly into generated environments.
“By observing a video of one of our teammates, the model can accurately insert them into any Sora-generated environment, capturing their appearance and voice,” the team notes.
