Latin America is the natural source for native Spanish and Portuguese training data at scale, with the English fluency needed to work directly from English-language guidelines. That combination is rare and it is exactly what multilingual data programs require.
Spanish is not one locale. Argentine, Mexican, Colombian and Chilean usage diverge in vocabulary, formality and humor, and models trained on European Spanish alone underperform for US Hispanic and LATAM users. We staff by locale, not just by language.
Safety and toxicity labeling is locale-dependent: slurs, euphemisms and culturally-specific harms do not translate. Native reviewers catch what a translated guideline misses, which is why we run native sign-off on every batch rather than sampling.

The Challenge
The model performed well in English and degraded badly in Spanish and Portuguese, with locale-specific safety failures that internal testing did not surface.
The Solution
Native pods in Mexico, Argentina and Brazil produced fine-tuning data, reviewed translations for cultural adequacy, and built locale-specific safety label sets with native sign-off on every batch.
The Results
- Native-quality datasets delivered across es-MX, es-AR and pt-BR
- Locale-specific harm taxonomy covering slang and euphemisms
- 100% of batches signed off by a native reviewer
- Cultural adequacy review applied to all model-facing copy
- Program ran with full US timezone overlap for guideline changes
