RLHF & Prompt Tuning: Crafting Multi-Turn Datasets for Specialized LLMs

Taming Foundation Models for Enterprise Domains

General-purpose Large Language Models (LLMs) often hallucinate or fail when confronted with highly technical medical, legal, or financial inquiries. Reinforcement Learning from Human Feedback (RLHF) and Direct Preference Optimization (DPO) bridge this gap.

The Anatomy of High-Value Preference Datasets

Creating robust alignment datasets requires domain-matter specialists who evaluate candidate outputs against multi-dimensional criteria:

• Factuality & Grounding: Verifying assertions against internal knowledge bases.
• Tone & Brand Alignment: Adhering to professional persona constraints.
• Safety & Red-Teaming: Stress-testing against prompt injection and sensitive data leakage.

Pairwise Scoring vs. Direct Editing

Our empirical workflows show that a combined pipeline—where specialists rank model generations and then edit suboptimal responses—delivers the steepest loss reduction during policy model fine-tuning.
