RLHF and human feedback for AI alignment

Aligning AI With Human Values

Reinforcement Learning from Human Feedback is the process that transforms capable language models into safe, useful assistants. It requires skilled human evaluators who can consistently judge response quality, identify subtle safety violations, and provide the preference signal that reward models learn from. Our RLHF teams include trained evaluators, domain experts, and safety specialists who understand the nuances of AI alignment — from detecting hallucinations and reasoning errors to identifying cultural biases and harmful content generation.

  • Pairwise and listwise preference ranking
  • Safety evaluation and red teaming
  • Reward model training data generation
  • Hallucination detection and factual grounding
  • Multi-dimensional scoring (helpfulness, safety, honesty)
Capabilities

Human Feedback Services

Comprehensive evaluation and feedback workflows for every stage of the AI alignment process.

Preference Ranking

Side-by-side comparison of model outputs where evaluators rank responses on helpfulness, accuracy, completeness, and style. Produces the preference pairs that power DPO, PPO, and reward model training for model alignment.

Safety Evaluation

Systematic assessment of model outputs for harmful content, bias, misinformation, and policy violations. Our safety teams evaluate responses against your safety taxonomy and flag content requiring model correction or refusal training.

Red Teaming

Adversarial prompt crafting to discover model vulnerabilities, jailbreak vectors, and safety boundary failures. Our red team specialists probe models with creative attacks to identify weaknesses before they reach production users.

Hallucination Detection

Factual verification of model claims against source documents and world knowledge. Evaluators identify fabricated facts, unsupported claims, and reasoning errors to produce training signal that reduces model confabulation.

Multi-Dimensional Scoring

Rubric-based evaluation across multiple quality dimensions — helpfulness, harmlessness, honesty, instruction following, and format compliance. Provides rich, structured feedback that goes beyond simple preference comparisons.

Conversational QA

Human evaluation of multi-turn conversation quality — coherence, context retention, appropriate escalation, and graceful handling of out-of-scope requests. Critical for validating chat model behavior before deployment.

FAQ

Frequently Asked Questions

Our RLHF evaluators are university-educated professionals with strong analytical and writing skills. They undergo a rigorous training program covering AI alignment concepts, bias identification, safety evaluation frameworks, and your specific evaluation rubrics. We maintain specialized pools for domain-specific evaluation (medical, legal, coding) with relevant professional backgrounds.
We measure inter-annotator agreement continuously and maintain it above 85% through detailed rubrics, calibration sessions, and regular alignment checks. Evaluators work through calibration examples before each project, and borderline cases go through a multi-evaluator adjudication process to ensure the preference signal is clean and consistent.
We produce data compatible with all major RLHF implementations: OpenAI's PPO pipeline, Anthropic's Constitutional AI approach, DPO (Direct Preference Optimization), RLAIF, and custom frameworks. Output formats include pairwise comparisons, Likert-scale ratings, multi-dimensional rubric scores, and ranked lists.
