Vietnamese AI training data
Native Vietnamese data
your models can actually trust.
Preference data, evaluations, red teaming and cultural-context QA — built only by native Vietnamese speakers, for global LLM teams. Method-agnostic. Not just RLHF.
// 01 — What we deliver
Six data products, one quality bar.
Preference data
Pairwise RLHF / DPO comparisons with documented rationale.
Evaluation datasets
Multi-criteria Likert scoring with calibrated rubrics.
Constitutional AI
Principle writing grounded in Vietnamese norms and values.
Red teaming
Adversarial and safety testing in real Vietnamese contexts.
Synthetic data validation
Native QA on machine-generated Vietnamese at scale.
Cultural-context QA
Honorifics, dialects, idiom and code-switching, checked by hand.
// 02 — Why we're different
Quality is the moat.
Native speakers only. No translators, ever. Fluency you can't fake.
Regional dialect coverage. Northern, Central and Southern Vietnamese.
Documented edge cases. Sarcasm, code-switching, Gen-Z slang, honorifics.
40–50% lower cost. Than Scale AI and Surge AI, same rigor.
Cohen's Kappa — higher is more reliable.
// 03 — How a pilot works
