The work

Design evaluation tasks that distinguish genuine capability from pattern matching; write adversarial and edge-case prompts in your specialism; review model-generated research code, experiments and claimed results; grade reasoning on systems, theory and algorithms problems.

Who it suits

  • PhD in computer science, statistics or a related field with publications in machine learning, NLP, systems or theory.
  • Strong engineering skills; experience training or evaluating large models a plus.

How it works

  • Apply with your CV and the hours you can give. 5 to 20 hours a week suits most people; the work is remote and on your own schedule.
  • We verify your credentials, licence or degree and your identity before any paid work. Every piece of work traces to a named, verified expert.
  • A paid calibration task on the project's own guidelines comes first.
  • You are paid at the rate on this page for every hour of work that passes review. Rates rise with the difficulty of the project and your track record.

HUMXN is a new expert network (launched 2026). Payouts go through Stripe after identity and tax verification. Never pay to apply.
