The Goal

Create a competitive model-evaluation game where multiple AI models face off against each other.

The Rules

Create a game that support either automated head-to-head comparisons or user-driven judging.
Users can press Start to launch a round and watch the competition play out.
Deliver a final ranked list of models based on their performance.
Deploy it on Vercel with AI Gateway.

Types of games you can create

Simulation

Let the models play. Create autonomous simulations where multiple AI models run in parallel, racing or collaborating toward a goal.

Examples
  • Wordle Battle (Models vs. Game)
  • Speedrun QA & Coding Sprints
  • Multi-Agent Ecosystems

Human Evals

Let humans decide. Build interactive evaluation games where users judge AI outputs without knowing which model produced them.

Examples
  • Prompt Fight / Model Arena
  • AI Debate Club
  • Style Showdown & Creative Writing

Open Category

Break the rules. Create a hybrid of simulation and human interaction, or build something completely unexpected.

Examples
  • Join as player and race against AI
  • Interactive Hybrid Games
  • Experimental Interfaces
