# DPO (Direct Preference Optimization)

A more efficient alternative to RLHF that eliminates the separate reward model step. Trains the model directly on preference pairs. Simpler to implement, but can also cause Mode Collapse if training data contains Typicality Bias.

## Business Value

DPO enables faster, cheaper model fine-tuning for custom use cases. Ideal for enterprises wanting to adapt base models to their specific domain.

## Context Studios Perspective

We use DPO for rapid model customization when clients need domain-specific behavior. It's faster than RLHF and often sufficient for enterprise applications.
