Open-Sora 2.0 Explained

Open-Sora 2.0 is a fully open-source video generator that creates short videos from text prompts for around $200,000, significantly less than other state-of-the-art models. Text-to-video generation is more complex than image generation because it requires creating a sequence of images that flow together seamlessly over time. One approach to tackle this problem is to train a model directly to convert text into video. Another approach simplifies the problem with a two-step process: first, train a model to generate a high‑quality image from a text prompt, and then use that model and the image generated as a conditioning signal to generate a video. Open-Sora 2.0 adopts the second approach.
