Why it matters
Generating audio together with the video removes the separate sound pass that made earlier output feel unfinished.
Sora 2
Added 2025-09-30OpenAI's state-of-the-art video generation model.
Sora is OpenAI's video model, and the step that changed how finished the output feels is generating audio with the picture rather than leaving you to add sound afterwards. Combined with the ability to keep a consistent likeness across clips, that makes short-form output usable rather than merely impressive. The distribution choice is worth noting: it ships as a consumer app with a remix-oriented feed, so the product is as much about social creation as it is about the model.
