What the work looks like
AI labs need researchers to test whether their models really understand science. Tasks usually fall into four kinds.
Answer research-level questions
Write expert answers in your field, with the reasoning, so models learn how a scientist thinks.
Review AI science answers
Check AI answers for errors in facts, calculations and interpretation, and explain the correct result.
Design hard problems
Create questions that need real expertise to solve, the kind that separate a PhD from a search engine.
Check data and methods
Evaluate experimental designs, analyses and conclusions the way a careful reviewer would.

How it works
- Get matched
Answer four quick questions. We rank every open task by how likely you are to be hired.
- Apply on the platform
Apply where the task is posted. Most platforms run a short skills assessment or interview and an ID check.
- Work and get paid
Pick up tasks when it suits you. The platform pays you directly, on its own schedule.
Is it right for you?
A good fit if
- You have a PhD, are a postdoc, or have equivalent research experience
- You can spot a subtle error in a calculation or argument
- You write clear explanations of complex ideas
- You want flexible, remote work alongside research or teaching
Probably not if
- You're looking for a salaried research position
- You need guaranteed hours every week
- You don't have graduate-level training in a science
Questions scientists ask
What do AI training jobs for scientists involve?
You write and review science for AI models: answering research-level questions, checking AI answers for errors, designing hard problems and evaluating methods and data.
How much do scientists earn training AI?
Most science tasks on humaven pay between $80–$150 an hour, and specialist PhD roles go up to $200 an hour. Rates are set by each platform and shown on every task.
Do I need a PhD?
Many roles ask for a PhD or postdoc experience, but some accept master's graduates or current PhD students. Each task lists its requirements.
Which fields are in demand?
Physics, chemistry and biology come up most, along with materials science, computational biology and neuroscience.
Can I do this alongside my research?
Yes. Most tasks are flexible, with no minimum hours. Check your institution's or funder's rules on outside work.
How do I apply?
Answer four quick questions on humaven to see the science tasks you're most likely to get, then apply on the platform that posts the task. Expect a short assessment in your field.
