The work

You will help improve AI safety by reviewing prompts and AI-generated responses related to chemical, biological, radiological, and nuclear risks. The work focuses on judging model behavior, identifying safety concerns, and giving clear reference feedback.

  • Review prompts and AI-generated responses.
  • Classify safety risks in model outputs.
  • Evaluate how the model handles CBRN-related requests.
  • Rank responses based on their quality and safety.
  • Provide expert reference feedback for AI training.
  • Take part in red-teaming, which tests how models respond to risky prompts.

Requirements

This is a part-time contractor role for candidates with intermediate experience. The work requires subject knowledge relevant to CBRN safety and careful judgment when evaluating AI responses.

  • Time: Less than 20 hours per week.
  • Experience level: Intermediate.
  • Relevant knowledge: Chemistry, biochemistry, radiology, nuclear topics, and explosives.
  • Key skills: Safety-risk classification, response evaluation, ranking, red-teaming, and expert feedback.
  • Experience: Intermediate level
