The runway demonstrated new AI video technology that creates HD images in real time. The technology could be an exciting development in the world of entertainment, but some say it will make it even harder to spot fakes.
AI, along with misinformation and bad actors, are already undermining what people see online. But real-time AI video is an even bigger step, and the technology could be used to deceive people in the real world, as someone controlling an AI avatar reacts and reacts to a real person.
A breakthrough in real-time video generation.
As a research preview developed in @NVIDIA shared by @NVIDIAGTC This week we trained a new real-time video model running on Vera Rubin. HD video is generated instantly, with a first frame time of less than 100 milliseconds. Fully unlocked… pic.twitter.com/juafjvk0wm

Runway showed off the technology at NVIDIA GTC last week. The as-yet-unnamed model can generate images from a prompt literally in the blink of an eye (in just 100 milliseconds). If you’ve never used an AI video model before, it typically takes seconds, if not minutes, from the time you enter a prompt until you receive an AI video about your model from Google or OpenAI.
interesting engineering We report that this model will run on NVIDIA’s next-generation Vera Rubin architecture. The technology website says the model works close to how game engines render graphics, allowing frames to be streamed continuously.
This means that there could theoretically be live broadcasts and streams featuring AI characters and worlds that react to whatever happens.
It also affects the game. In January, Google announced Project Genie, a world-building tool that lets users create their own environments from a single photo or text prompts that unfold in real time.

For example, AI tends to wander from its source the more iterates, making it a challenge to maintain character consistency. But with companies like NVIDIA and their unlimited financial resources, great advances will continue to come.
