Role-based Prompting

Role-based prompting is a prompt engineering technique in which the language model is instructed to simulate a specific character, expert, or entity (e.g., 'You are a senior Java developer'). The goal of this method is for the model to narrow the space of possible responses and align the style, vocabulary, and professional depth of the output to the chosen profile. Applying a persona increases the relevance and contextual accuracy of responses, particularly for tasks requiring specialized professional knowledge, as the model activates its latent knowledge relevant to the given role.
