• Write explanations for why one response is superior
• Flag responses that contain errors, bias, or harmful content

Red Team / Safety Trainers ($40-120/hr)

Red team trainers try to break AI systems — finding ways to make models produce harmful, biased, or incorrect outputs. This is a growing segment as AI companies invest heavily in safety.

What you do daily:

• Craft adversarial prompts to test model safety boundaries
• Document failure modes and categorize them by severity
• Evaluate model responses to sensitive or controversial topics
• Test for bias, stereotyping, and harmful content generation

What you need: Creative thinking, understanding of AI risks, and ethical reasoning. Technical background is helpful but not always required.

Salary by Platform

Salary by Experience Level

Your track record on the platform and in the field significantly impacts your rate:

• Beginner (0-6 months): Expect entry-level rates. Focus on building quality scores and completing assessments.
• Intermediate (6-18 months): Access to mid-tier projects. Quality scores and reliability unlock better work.
• Advanced (18+ months): Eligible for premium projects, team lead roles, and invitation-only tasks. Top performers at this level earn 2-3x what beginners make on the same platform.

How to Maximize Your AI Trainer Salary

1. Complete every available assessment. Your assessment scores directly determine your rate tier on most platforms. A strong assessment can mean $40/hr instead of $25/hr for the same tasks.

2. Specialize, then go deeper. General RLHF pays $20-50/hr. Specializing in code review jumps you to $50-150/hr. Adding a domain expertise layer (e.g., code review + security expertise) pushes rates even higher.

3. Maintain quality above 90%. Quality scores below 90% restrict access to premium tasks. Above 95% opens invitation-only projects.

4. Use multiple platforms strategically. Keep your primary work on a high-paying platform (Mercor, Braintrust) and use secondary platforms for backup during slow periods.

5. Track your effective rate. Some tasks take longer than others. Calculate your actual earnings per hour, not just the posted rate, to identify your most profitable task types.
