Generative Video at the Speed of Light — Keegan McCallum, uRun

McCallum says at least **40 real-time or long-horizon models** appeared this year. At current cited pricing, **$10 buys about 3 hours** of continuous generated video and $50 buys about 15 hours, with steering possible in under a second.

Builders can start treating video as a live agent surface rather than a render job: interactive avatars, webcam transformations, and observable agent output. The underlying harness needs GPU placement, WebRTC infrastructure, frame-level controls, and asynchronous model pipelines.

The cost and quality claims come from the provider’s talk and are not a cross-provider benchmark. Real-time output is described as comparable to older frontier quality, so higher fidelity may still require a separate render step.
