What this actually is

You bring your specialist expertise to AI evaluation. The shape of the work varies but the pattern is the same: review outputs, rate quality, write prompts, flag errors. The platform title (IMO Experts) reflects the rate band and the expertise required, not the day-to-day work.

  • Write original & advanced IMO-style mathematics problems to challenge frontier AI models
  • Evaluate AI-generated solutions for correctness, clarity, and style
  • Identify logical flaws, incomplete reasoning, or insufficiently-rigorous proofs
  • Provide clear, concise, and correct solutions & chain of thought reasoning
  • Maintain extremely high standards of mathematical precision and problem difficulty

**Compensation**

  • Compensation per task varies based on factors such as problem difficulty, solution quality, and overall efficiency, and contributors are free to choose how many tasks they complete.
  • There is no cap on total weekly payments for services rendered; contributors may complete as many available tasks as they choose to accept during the engagement.

**Application Process**
