Over the National Day holiday period, on September 30th, OpenAI unveiled its latest and most sophisticated video - generation model, Sora 2. Alongside this release, an iPhone app called 'Sora by OpenAI' was also introduced. Sora 2 has brought about remarkable enhancements in video - generation capabilities. It's not just about creating high - definition visuals anymore; the model can now simultaneously generate corresponding audio, dialogue, and ambient sound effects. What's more, it can accurately synchronize lip movements, delivering an immersive 'audio - visual integrated' experience.

Moreover, Sora 2 has made substantial leaps in physical simulation. It can precisely model intricate movements and physical phenomena, mimicking real - world scenarios with great accuracy. In a mere matter of days, the Sora app shot to the top of the charts on the U.S. App Store, outperforming OpenAI's own ChatGPT and Google's Gemini.
