RLHF and Human Feedback Data for LLM Alignment
Aligning large language models with human values requires more than automated benchmarks. Centric Labs provides expert human evaluators who generate the preference data, rankings, and reward signals that make RLHF, DPO, and Constitutional AI work at scale. Our evaluators are trained researchers and domain experts — not anonymous crowd workers — ensuring the nuanced judgment that LLM alignment demands. From instruction-following evaluation to safety red teaming, we deliver the human intelligence layer that keeps your AI aligned, helpful, and safe.
Comprehensive Human Feedback Services for AI Alignment
Human preference ranking including pairwise comparison, Likert-scale rating, and best-of-N selection. Instruction-following evaluation measuring helpfulness, accuracy, and relevance of model responses. Safety and harmlessness evaluation for toxicity, bias, and harmful content detection. Red teaming services including adversarial prompt generation and vulnerability testing. Reward model training data with calibrated human judgments across multiple dimensions. Supervised fine-tuning (SFT) data including expert-written instruction-response pairs for domain adaptation.
What you get
- Dedicated managed teams, no anonymous crowd
- Multi-stage QA with measurable SLAs
- Secure workflows designed for enterprise data
- Fast pilots with clear success criteria
Expert Evaluators, Not Anonymous Raters
The quality of RLHF data depends entirely on evaluator quality. Our human evaluators include domain experts in medicine, law, finance, and engineering, trained researchers with graduate-level education, native speakers for multilingual evaluation, and calibrated teams with regular inter-rater reliability testing. Every evaluator is trained on your specific evaluation rubric and taxonomy before contributing to your project. We maintain full traceability so you know exactly who evaluated what and when.
