METHODLLM Arena
Judge the output, not the name.
A repeatable format for comparing visible model behavior on the same practical prompt. The rules are intentionally simple and the limits are part of the result.
Fairness rules
- Every model receives the exact same prompt text.
- Runs use the same prompt, with model-specific API limits recorded alongside each output.
- The first response is kept. No retries, repair prompts, or follow-up.
- Outputs retain model version, timestamp, token usage, and latency when available.
- Model names remain hidden until after the visitor votes.
Security rules
Model-generated HTML and JavaScript are untrusted code. Build outputs render inside sandboxed iframes with scripts allowed but without same-origin privileges.
<iframe sandbox="allow-scripts" referrerpolicy="no-referrer"></iframe>Generated HTML is never injected into the main page. SVG outputs are isolated or sanitized before publication.
What this is not
This is not an ELO leaderboard, a scientific benchmark, or a claim that one model is globally better than another. It is a clear, repeatable way to inspect real model behavior side by side.
