Code2Video-AA benchmark ranks Claude Opus 5.5 first among 27 AI models at making marketing videos from code

Artificial Analysis has a new way to grade AI models: ask them to make a marketing video, then let people judge the results blind. The benchmark is called Code2Video-AA, and its first leaderboard covers 27 models. Claude Opus 5.5 finished on top with an Elo rating of 1536, ahead of every rival on every scoring axis. How the test works Artificial Analysis launched Code2Video-AA on October 26, 2026. The setup asks each model to turn a design brief into a finished, self-contained video. The catch is that no model paints pixels directly. Each one writes code instead, building HyperFrames HTML compositions and animating them with GSAP, a JavaScript animation library. The briefs number 114, all centered on product and brand marketing. Three tasks from the public split of the underlying Code2Video Bench are posted with every model’s rendered video, so anyone can compare outputs side by side. Scoring relies on blind pairwise comparisons. Evaluators see two videos without knowing which model made them, then pick the better one. Those head-to-head results are converted into Elo ratings for each of five axes: Engagement: does the video hold attention Prompt Intent: does it deliver what the br...
