Tips

How to get the
most out of it.

Most people just open it and use one model. Here's how to actually use it properly.

1
Run the same prompt on multiple models
The whole point of Arena is comparison. Paste the same prompt into Claude, GPT-5, and Gemini back to back and see which one gives the best answer for your specific task. Different models win on different things.
2
Pick the right model for the right job
Don't use one model for everything. Claude for writing and instructions. GPT-5 for coding and math. Gemini for research and long documents. Switching costs nothing on Arena.
3
Use it to test prompts before committing
Before you build a workflow or automation around a specific model, test your core prompts on Arena first. Find out which model actually handles your use case best — then commit to that one.
4
Check the leaderboard before choosing
Arena has a live leaderboard at arena.ai/leaderboard showing which model is ranked best right now based on real user votes. The rankings update constantly as new models drop — check it before starting a big task.
5
No login needed to start
Go straight to arena.ai/text/direct and start prompting immediately. No account, no credit card, no setup. Just open it and go.
