Artificial Analysis has launched the Code2Video-AA benchmark to evaluate the video generation capabilities of 27 AI models. Claude Opus 5.5 leads the leaderboard with an Elo rating of 1536 based on blind pairwise comparisons.
Why it matters
The benchmark provides a standardized performance metric for AI video generation, helping users navigate a market where task costs range widely from $0.01 to $3.89 per output.
Claude Opus 5.5 achieved a top Elo rating of 1536 across 114 design briefs, significantly outpacing the 1052 to 1053 Elo range of leading open-weight models.
The players
Artificial Analysis
An independent organization that tracks and benchmarks performance metrics across various large language models and generative AI systems.
Claude Opus 5.5
The top-performing proprietary AI model on the new benchmark, developed by Anthropic.
GPT-6 Astra
An AI model developed by OpenAI that secured the third-place position on the benchmark.
The details
The benchmark evaluates models by their ability to write HTML compositions animated with the GSAP JavaScript library, a tool for creating high-performance animations. Evaluators perform blind pairwise comparisons of the resulting rendered videos to calculate Elo ratings, a system originally designed for chess rankings to measure relative skill levels.

The Tech Race
The leaderboard highlights a performance gap between top-tier proprietary models like Claude Opus 5.5 and the current field of open-weight alternatives. As these models compete to master complex UI animation and video synthesis, benchmarks like Code2Video-AA define the new standard for model efficacy.
Users can now compare the animation quality and efficiency of 27 different models, with task costs ranging from $0.01 to $3.89 per output. This allows businesses and developers to weigh specific performance ratings against the cost-per-task when selecting a model for production workflows.
The takeaway
The Code2Video-AA benchmark establishes a clear hierarchy for video generation models, with Claude Opus 5.5 currently setting the pace. Future updates will reveal if the performance gap between top proprietary models and open-weight architectures continues to widen or compress.
