# Frequently Asked Questions

Find answers to common questions about the DualMind Arena platform.

## General

<AccordionGroup>
  <Accordion title="What is DualMind Arena?">
    DualMind Arena is a crowdsourced AI evaluation platform. It allows you to compare two AI models side-by-side using the same prompt. By voting on the better response without knowing the model names beforehand ("blind testing"), the community creates an unbiased leaderboard of model quality.
  </Accordion>

  <Accordion title="Is DualMind free to use?">
    Yes! The platform is free for public use to help democratize AI evaluation.
  </Accordion>

  <Accordion title="Why blind comparison?">
    Knowing a model's name (e.g., "GPT-4" or "Claude 3") creates subconscious bias. Blind comparison forces you to evaluate the *content* of the response, not the *brand* of the model, leading to more accurate quality data.
  </Accordion>
</AccordionGroup>

## Comparisons & Voting

<AccordionGroup>
  <Accordion title="How are models selected?">
    In **Random Mode**, the system selects two different models from the active pool at random.
    In **Topper Mode**, the current highest-ranked model is paired against a random challenger.
    In **Manual Mode**, you explicitly choose which two models to compare.
  </Accordion>

  <Accordion title="How is the leaderboard calculated?">
    We use an ELO rating system similar to chess. When Model A beats Model B, Model A gains points and Model B loses points. The amount of points depends on the rating difference — beating a high-rated model awards more points than beating a low-rated one.
  </Accordion>

  <Accordion title="Can I change my vote?">
    Votes are final once submitted to ensure the integrity of the leaderboard and prevent manipulation.
  </Accordion>
</AccordionGroup>

## API & Integration

<AccordionGroup>
  <Accordion title="How do I access the API?">
    You can attain an API token by logging into the web interface. This token allows you to submit prompts, retrieve comparisons, and vote programmatically. See the [API Reference](/api-reference/introduction) for details.
  </Accordion>

  <Accordion title="Is there a rate limit?">
    Yes, to ensure fair usage for everyone, the API has rate limits. Authenticated users have higher limits than anonymous usage.
  </Accordion>

  <Accordion title="Can I use DualMind for commercial benchmarking?">
    Please contact us for enterprise licenses or commercial usage of the comparison data and API.
