Claude Opus 5.5 Enables Code-Rendered Video Generation, Cuts Costs 40 Percent

Anthropic released Claude Opus 5.5 on September 22, 2026, a new flagship model that excels at generating video through long-horizon code generation. The model creates complex JavaScript, p5.js, or Three.js programs that render video frame-by-frame when executed, eliminating the need for manual camera work or editing software. The capability emerged prominently in the days following release, with developers publishing code-rendered animations and films built entirely by the model—including a three-minute film about AI history with every frame procedurally generated and a music video where Claude wrote the narrative, all visual elements, and synthesized the soundtrack.
