Better Models Start with Better Human Feedback

AI systems perform best when they understand what humans prefer. 

Preference Data

How We Build Preference Data for AI

Differing languages, cultures, and specialized domains all require structured human evaluation, calibrated reviewers, and rigorous quality control. 

DATAmundi generates high-quality preference datasets through structured human feedback, pairwise ranking, comparative assessment, and expert review to support model training, fine-tuning, and alignment.

Human Preference Ranking

We generate structured preference datasets through pairwise comparisons, response ranking, and comparative evaluation. Trained human reviewers assess model outputs against defined criteria, including accuracy, helpfulness, relevance, and instruction-following.

Rubric-Based Evaluation + Scoring

Our experts apply task-specific evaluation rubrics and structured scoring frameworks to capture consistent human judgments. Combine clear annotation guidelines, reviewer calibration, and expert oversight to deliver reliable preference signals.

Multilingual + Cross-Cultural Preferences

With 25+ years of expertise in language and AI, we capture human preferences across 200+ languages, cultures, and regions. Our DATAtalent global contributor network evaluates linguistic quality, cultural appropriateness, contextual relevance, and user expectations to support globally relevant AI systems.

RLHF + Fine-Tuning Data

Develop human preference datasets for reinforcement learning from human feedback (RLHF) and related post-training approaches, alongside expert-reviewed data for supervised fine-tuning (SFT) workflows.
