Size and Specialization of SFT Datasets
The datasets used for Supervised Fine-Tuning (SFT) have distinct characteristics compared to those used for pre-training. An SFT dataset is typically much smaller in volume but is highly specialized, containing curated data directly relevant to the target tasks.

Definition of SFT Datasets
A development team starts with a base language model that has been pre-trained on a massive, general-purpose dataset from the web. To make the model a specialized customer service chatbot, the team initiates a second phase of training. How would the dataset used in this second phase most likely differ from the original pre-training dataset?

Adapting a Model for a New Task
A law firm wants to develop a language model that can take a lengthy legal contract as input and produce a concise, one-paragraph summary highlighting key clauses like the term, liability limits, and governing law. They have a team of paralegals available to create a high-quality dataset of several thousand contract-summary pairs. Which of the following approaches is the most effective and direct way to train the model for this specific task?
