Two models · One prompt · Your verdict
Battle the frontier
Send one prompt to two AI models, compare the answers side by side, and vote for the better one. Reader battles feed the community signal behind our leaderboard.
Demo mode — responses are simulated until API keys are added to .env. Voting still works and counts.
Get started
How it works: both models receive your exact prompt. With API keys configured, responses come live from the providers; otherwise the page runs in clearly-labeled demo mode. Votes are stored (never your full prompt history) and counted as community signal alongside our editorial Elo. Model ratings are our editorial index — not a vendor benchmark.
