RLHF, DPO, and the Evolution of Alignment Training

Pretraining produces capable models, but raw pretrained models are not useful assistants. Alignment training is what shapes them into the helpful, honest, and harmless systems users actually interact with. The techniques have evolved rapidly from RLHF to DPO to constitutional AI, each addressing limitations of the previous approach.

What is Model Training in AI?

Model training is the process of teaching an AI system to perform a task by exposing it to data and adjusting its internal parameters to minimize errors. It's where the actual 'intelligence' of an AI system gets built — and where most of the time, money, and engineering effort gets spent.
