How do LLM alignment techniques ensure safer and more controllable AI systems?

LLM alignment techniques modify model behavior so outputs better match human intentions, ethical constraints, safety requirements, and organizational goals.

Alignment refers to ensuring that a model behaves in ways humans actually want. Raw pretrained LLMs optimize next-token prediction, not human values, safety, or correctness. Without alignment, models may generate harmful, biased, manipulative, or unsafe outputs.

Modern alignment pipelines combine multiple strategies:

The model is trained on curated examples demonstrating desired behavior.

Humans rank responses and reward models guide optimization.
