Sora 2 is OpenAI’s state-of-the-art video and audio generation model, building on the original Sora with enhanced realism, synchronized audio, and improved physics simulation. It enables users to create imaginative, high-fidelity videos that follow users direction closely, supporting a wide stylistic range and dynamic prompts. Sora 2 introduces features such as hierarchical diffusion, temporal attention, and physics-aware priors, making it suitable for storytelling, marketing, education, and more. Safety measures include restricted access, moderation thresholds, and safeguards against misuse, especially for content involving minors and photorealistic likenesses.
