Definition
Plain language
The post-training stage that shapes a model to be helpful, harmless, and honest.
As stated in the literature
Post-training procedures including SFT and RLHF that shape model behavior toward desired norms after pretraining.
Also called: alignment
Why it matters: It's the stage that turns a raw next-token predictor into something people can actually deploy as an assistant.
For example, a base model that will happily generate dangerous instructions can be alignment-trained to refuse such requests and explain why.
Heard on the show
“… raw performer actually hacks a bit more, which is why the paper insists the supervisor select for alignment rather than raw score. …”Episode 199 — Finding a Model's Hidden Behaviors Without Knowing What You're Looking For
