Your ranking
Only from your own votes, saved in this browser. Vote in a few duels and your personal ranking appears here.
How it works
- Blind: you see the names only after you vote, so the brand cannot change your mind.
- Only free models: gpt-oss-20b, gpt-oss-120b, Gemma 4 26B A4B, mistral-small-3.1-24b-instruct-2503, llama-3.1-8b-instruct, llama-4-scout-17b-16e-instruct, qwen3-30b-a3b, DeepSeek-V4-Flash (High). They run on Cloudflare Workers AI.
- Your privacy: we save only your vote (which model was A, which was B, who won), never your question or the answers. Details
- The ranking: all votes become the Free Arena leaderboard, computed like Arena’s own method (Bradley-Terry). A model enters it after 300 votes; until then the main leaderboard uses Arena’s public votes.
