# AI Video Generation Benchmark — Which LLM Codes the Best Video?

An **AI video generation benchmark** that pits 12 LLMs against the same creative
briefs. Each model is asked to generate motion-graphics animation code, which is
then compiled and rendered to a real video — same pipeline for every model, no
hand-fixing in between. The result is a side-by-side **leaderboard** plus a
gallery of every rendered clip, so you can judge the **best LLM for video** with
your own eyes.

This is a free, no-signup mirror of the full
**[AI Video Generation Benchmark on MesmerTools](https://mesmer.tools/benchmarks/ai-video-generation)**.

## What's inside

- **The leaderboard** — every model ranked by output quality, with videos
  rendered, average generation time, average code size, total cost, and retry
  count. A clean read on which model is the **best LLM for motion graphics**.
- **Every result, brief by brief** — seven prompts (YouTube intro, SaaS teaser,
  Instagram story, app walkthrough, smartwatch reveal, music "wrapped" recap,
  sneaker drop) with each model's rendered video, plus the failures shown
  honestly.
- **Claude vs Gemini vs GPT video**, head to head — Claude Fable 5, Claude Opus
  4.8, Claude Sonnet 4.6, GPT-5.5, Gemini 3.1 Pro, Gemini 3.5 Flash, DeepSeek V4,
  Kimi K2.6, GLM 5.1 / 5.2, and MiMo V2.5 Pro.

## How it works

The page fetches a single generated JSON
(`https://mesmer.tools/benchmarks/ai-video-generation.json`) directly in your
browser and renders the leaderboard and video gallery. The data is regenerated
whenever MesmerTools redeploys, so the benchmark stays current with no backend.
