Continuous Prompts (Soft Prompts)
Continuous prompts, also known as soft prompts, are implicit and adaptable prompting patterns that exist as hidden, distributed representations directly within the embedding space of a Large Language Model. Unlike human-readable hard prompts, they are not required to correspond to meaningful text. Instead, soft prompts are treated as learnable parameters that are optimized through continuous optimization, enabling the exploration of prompting methods beyond discrete, user-defined text.

A development team is using a pre-trained large language model to build a chatbot for customer support. They observe that the model's responses, while fluent, do not consistently adhere to the company's specific tone and policy guidelines. To address this, the team begins a process of methodically crafting and testing various instructions and examples as inputs to guide the model's output, without altering the model's internal weights. This process involves numerous cycles of adjusting the input text to achieve the desired response quality. Which discipline best describes the team's primary activity?

Choosing the Right Prompting Strategy
A key distinction of a continuous prompt is that it exists as a sequence of learnable numerical vectors within a model's embedding space, rather than as a sequence of discrete, human-readable words. Which of the following is the most direct consequence of this architectural difference?
Prompt Tuning
A research team is developing a specialized question-answering system for a fixed, well-defined medical domain. Their primary constraints are a limited computational budget for model adaptation and the need for the highest possible task performance. Given this context, which of the following best describes the fundamental trade-off the team accepts by choosing to implement continuous prompts instead of manually crafted discrete prompts?
