How this pay compares

The title points to rating and reviewing ai output: judging a model's answers or code against guidelines, such as which of two is better or whether one is correct and safe. What each kind of AI training work pays

At $50/hr, this role pays more than 21% of the 43 open physics roles with a listed pay range, below the median of $75.

Open physics roles that ask for a Master's have a median of $68/hr (14 roles).

Among platforms with 10 or more priced physics roles, OpenTrain AI has the highest median ($95/hr across 20 roles) and Alignerr the lowest ($45/hr across 11).

OpenTrain AI roles that closed since late October stayed listed a median of 31 days (122 roles). OpenTrain AI posted this one 6 days ago.

Computed from 2,746 open roles we track across Mercor, micro1, Handshake AI, Alignerr, Appen and OpenTrain AI, refreshed daily. Midpoints of listed ranges; “up to” ceilings are left out of medians.

The work

You will help improve AI systems by creating physics questions and reviewing their answers. Your feedback will focus on accuracy, logical consistency, mathematical rigor, and sound physical reasoning.

  • Design questions that test physical reasoning and mathematical modeling.
  • Review AI-generated physics responses for correctness and logical consistency.
  • Identify weaknesses in technical explanations and judgments.
  • Give clear feedback on physics and related mathematical concepts.

What it pays and takes

This is remote, project-based contract work that can fit alongside study, research, teaching, or industry work. Work is available when active projects need contributors.

  • Pay: Up to $50 per hour.
  • Schedule: Flexible and asynchronous, with approximately 5 to 20 hours per week during active projects.
  • Minimum hours: No minimum hour requirement.
  • Location: Open to candidates in the United States.
  • Language: Fluent in English.
  • Education: A master's student or graduate in physics, applied physics, astrophysics, engineering physics, or a closely related field.
  • Skills: Strong physical reasoning, mathematical modeling, analytical problem-solving, attention to mathematical rigor, and technical content evaluation.
  • Helpful background: Physics research, teaching, coursework, or quantitative industry work. Prior AI or technical experience is not required.
