Amazon Nova 2 Lite: Fine-tuning vs. Continued Pre-training Explained

By PulseAugur Editorial · [1 sources] ·

Adapting large language models like Amazon Nova 2 Lite for specialized domains involves two primary methods: continued pre-training (CPT) and supervised fine-tuning (SFT). CPT uses large volumes of unlabeled text to enhance the model's domain knowledge and fluency, akin to providing a specialist with a professional library. SFT, on the other hand, trains the model on labeled prompt-response pairs to teach specific tasks, behaviors, formats, or styles, similar to showing worked examples of assignments. The choice between CPT and SFT depends on whether the primary goal is to increase domain knowledge or to shape the model's behavior and task execution. AI

IMPACT Clarifies distinct methods for adapting LLMs, guiding developers on choosing between knowledge acquisition and behavior shaping for specialized tasks.
