If you don’t know Sora 2, you should. OpenAI’s Sora 2 generates realistic and imaginative videos all from your text prompts.It can create videos with complex scenes, multiple characters, and accurate motion, and is also capable of generating sophisticated audio, including dialogue and sound effects. Users can also start from an image, and the app's functionality is similar to other short-form video platforms.
Their latest video generation model is more physically accurate, realistic, and more controllable than prior systems. It also features synchronized dialogue and sound effects.
The original Sora model from February 2024 was in many ways the GPT‑1 moment for video—the first time video generation started to seem like it was working, and simple behaviors like object permanence emerged from scaling up pre-training compute. Since then, the Sora team has been focused on training models with more advanced world simulation capabilities. We believe such systems will be critical for training AI models that deeply understand the physical world. A major milestone for this is mastering pre-training and post-training on large-scale video data, which are in their infancy compared to language.
The model is also a big leap forward in controllability, able to follow intricate instructions spanning multiple shots while accurately persisting world state. It excels at realistic, cinematic, and anime styles. As a general purpose video-audio generation system, it is capable of creating sophisticated background soundscapes, speech, and sound effects with a high degree of realism. The model is far from perfect and makes plenty of mistakes, but it is validation that further scaling up neural networks on video data will bring us closer to simulating reality.
Sora 2 availability and what’s next
Sora 2 is available to download now with the initial rollout in the U.S. and Canada with the intent to quickly expand to additional countries. Sora 2 will initially be available for free, with generous limits to start so people can freely exploreits capabilities, though these are still subject to compute constraints.ChatGPT Pro users will also be able to use experimental, higher quality Sora2 Pro (and soon in the Sora app as well).
Video models are getting very good, very quickly. General-purpose world simulators and robotic agents will fundamentally reshape society and accelerate the arc of human progress. Sora 2 represents significant progress towards that goal. In keeping with OpenAI’s mission, it is important that humanity benefits from these models as they are developed. We think Sora is going to bring a lot of joy, creativity and connection to the world.
