Every frame of this video is code. No stock art, no image model. The watercolor washes, ink strokes, and the little robot are painted procedurally, frame by frame. Made this 13-minute post-training explainer with Opus 5.5 in Claude Code. Opus planned and handled the production: script, scenes, fact-checking, voiceover via TTS, and music pipeline.
