MODEL ADAPTATION • 229 / 397
Know when to prompt, retrieve, fine-tune or compress a model.
PEFT
PEFT means parameter-efficient fine-tuning: methods that adapt a model by training only a small subset or additional parameters.
Think of it like
Think of PEFT as changing how a trained worker behaves or how efficiently that worker can be deployed, rather than giving it a live reference book.
Real life
Organizations adapt general models using techniques such as PEFT.
SRE lens
Useful when full-model fine-tuning is too expensive.
