I asked GPT-6 Astra for a video about "time". It made the whole thing in javascript, from the big bang to itself writing the code for this video

GPT-6 Astra generated a video about "time" entirely in JavaScript, rendering each 4K frame using p5.js and the p5.brush library. The video's narrative spans from the big bang through the evolution of Earth, life, and human civilization, culminating in Astra itself writing the code for the video, before returning to a single dot. This showcases Astra's capability to create complex visual content programmatically.

Unlike earlier AI video generators, Astra created the entire video programmatically in JavaScript, rather than from pre-existing assets or models.
