Alexandr Wang says Muse Spark recut a video into a shitpost overnight

Alexandr Wang says he ran Muse Spark overnight to cut a video into scenes, recreate each one, and judge every take against aesthetic criteria he set.

He says the model kept assembling scenes until it produced a finished video, which he calls shitpost material. His post on X from October 13, 2026 is the only report, and it includes no output or comparison showing how the result was judged.
