DPO — Direct Preference Optimization
Definition: A training method that aligns models to human preferences using ranked pairs directly, skipping the reward-model step of classic RLHF. Simpler pipeline, fewer moving parts, often comparable results.
Example
Switching from RLHF to DPO cut our alignment training time in half with no measurable quality drop.
When you'll hear it
DPO shows up most often in AI strategy reviews, model evaluation discussions, and product roadmap meetings. When someone uses it, they're usually referring to direct preference optimization — and they expect the room to already know what that means.
