Overview
Sora 2 is OpenAI's flagship text-to-video and image-to-video model, and the release many called a "GPT-3.5 moment" for AI video. After the original Sora spent eighteen months as the model everyone had heard of but almost no one could use, Sora 2 shipped a genuinely usable product: physics-aware motion, multi-shot scenes longer than most rivals, and native synchronized audio that approaches Veo's fidelity.
Its standout features are best-in-class physics and the social-first "Cameos" system that makes personal video generation effortless. Sora 2 beats Runway Gen-4 on photorealism and prompt adherence and ranks among the top text-to-video models on the Artificial Analysis Arena. Audio is included at no extra charge, and the model supports remix and extend features that few competitors match at its price.
