OpenAI's Sora 2 may not show significant technical innovation, but it introduces a new approach to its business model by combining text-to-video technology with social media platforms. Sora's product design reflects an understanding of social media dynamics. Since social media thrives on frequent interactions, Sora limits video generation to 10 seconds to align with users' habits of consuming content quickly. This length restriction also leaves room for potential paid services in the future, such as generating longer videos. From a functionality perspective, Sora's Cameo feature clearly emphasizes social engagement. Users can create their own virtual avatars and generate personalized content based on them, enhancing user participation and interactivity. In terms of promotional strategies and copyright management, Sora has made specific arrangements. Sam Altman has publicly shared his virtual avatar for community use to help spread platform memes. Meanwhile, regular users can set permissions for their virtual avatars, encouraging social interaction and creative exchange. To address concerns about the authenticity of AI-generated videos, Sora has implemented several safety measures. Videos undergo preliminary review before generation, and dynamic watermarks—possibly invisible ones—are randomly embedded to reduce the risk of misuse. So, I think Sora 2 is not just a straightforward application of technology but rather a comprehensive attempt based on market demand and technological capabilities.
