About AI Model Arena
A tool for comparing AI models side-by-side in real-time.
What is AI Model Arena?
AI Model Arena lets you send the same prompt to multiple AI models simultaneously and compare their responses, costs, and latency in real-time. Currently supports Gemini, Claude, GPT, and Grok from Google, Anthropic, OpenAI, and xAI.
Choose between Fast mode (cost-effective models like Gemini Flash, Claude Sonnet, GPT-4o Mini) and Frontier mode (best-in-class models like Gemini Pro, Claude Opus, GPT-5) depending on your needs.
An AI judge (randomly selected from the same models) evaluates and ranks the responses based on accuracy, clarity, completeness, and usefulness.
Features
Real-time Comparison
Send one prompt to all four AI models and see responses stream in simultaneously.
AI Judge
An impartial AI judge evaluates and ranks responses based on multiple criteria.
Cost & Latency Tracking
Track token usage, API costs, and response latency for each model.
Open Source
Built with Next.js, TypeScript, and Tailwind CSS. Check out the source on GitHub.
How It Works
- Enter a prompt in the input field
- Your prompt is sent to all four AI models in parallel
- Each model's response streams back in real-time
- If judging is enabled, a randomly selected AI evaluates all responses
- View rankings, scores, and detailed feedback for each response
