What STEM experts actually do for your AI training pipeline
Reasoning data generation
Model output evaluation
Domain-specific benchmarking
Rubric design and calibration
Why LATAM STEM talent, specifically
Brazil, Mexico, Argentina, Chile, and more graduate a deep bench of STEM PhDs and Master's students every year, many from universities with strong research output in physics, chemistry, engineering, math, computer science, and others.
Academic depth
Candidates often carry publications in journals like Nature, IEEE, or Physical Review, and bring postdoc-level research experience in their field.
Cost
A senior STEM researcher costs 40-60% less than an equivalent hire in the US or Europe, without a drop in quality.
Timezone
Brazil, Mexico, Argentina, and Chile all sit 1-3 hours from US Eastern time. A question about a batch of reasoning data gets answered the same morning.

Frequently asked questions
What is a STEM expert in the context of AI training?
.svg)
A STEM expert is a professional with an advanced degree, usually a PhD or Master's, in physics, chemistry, biology, mathematics, or engineering, who applies that domain knowledge to generate, evaluate, or grade AI training data. Their value is in catching errors and reasoning gaps that a generalist rater without the subject background would miss.
Why do AI labs need domain experts instead of generalist annotators?
Generalist annotators can flag whether an answer sounds coherent, but they can't verify whether a multi-step derivation in chemistry or physics is actually correct. As models get evaluated on harder, more specialized reasoning tasks, labs need reviewers who can independently solve the problem themselves, not just check the model's tone.
How much does it cost to hire STEM PhDs for AI training?
Rates depend on domain, task complexity, and volume, but LATAM-based STEM PhDs typically cost 40-60% less than equivalent US or European hires.
Where are Athyna's STEM experts located?
Primarily Brazil, Argentina, Mexico, and LatAm in general with academic backgrounds from research universities across the region.
Can STEM experts help build evaluation benchmarks, not just review data?
Yes. Beyond one-off review, STEM experts on Athyna can help design domain-specific benchmarks and grading rubrics, so your evaluation process holds up as your model and your task set both evolve.
