Prompting in Language Models
Prompting is a technique for guiding a pre-trained language model to perform a specific task by structuring its input as a textual instruction or query. This method leverages the model's existing knowledge to generate desired outputs without needing to update its parameters through retraining. It is a foundational mechanism that enables advanced application strategies such as zero-shot and few-shot learning.

Fine-Tuning as a Mechanism for Activating Pre-Trained Knowledge
A startup wants to adapt a large, pre-trained language model to classify customer sentiment (positive, negative, neutral). They have a very small labeled dataset (fewer than 500 examples) and extremely limited access to high-performance computing, making extensive retraining financially unfeasible. Which adaptation approach is most suitable for their situation?
Efficiency of LLM Adaptation via Prompting
A developer intends to specialize a general-purpose, pre-trained language model for a new text classification task by updating its internal parameters. Arrange the following steps in the correct chronological order to accomplish this adaptation.

A team is tasked with adapting a large, pre-trained language model to summarize legal documents. One developer designs a method where each summarization request includes a detailed set of instructions and examples of high-quality summaries, which are provided to the original, unchanged model. Another developer uses a large dataset of legal documents and their corresponding summaries to make small, permanent adjustments to the model's internal configuration before deploying it.

Components of a Prompt: Instruction and User Input
When a language model successfully performs a new task based on a well-crafted prompt, its internal parameters are temporarily adjusted for the duration of that specific task to better align with the provided instructions.
