The work

  • Write, refine, and stress-test prompts across varied scenarios and edge cases.
  • Evaluate responses for accuracy, helpfulness, and safety.
  • Find differences between ratings and the grading guidelines, then correct them.
  • Record findings and submit evaluation datasets through AI training tools and platforms.
  • Take part in quality reviews and work with trainers and other contributors to refine guidelines.
