Prompt Priming

Prompt priming involves providing an initial set of instructions or context to guide the behavior of a language model. This technique can be used to elicit responses from the model that align with a specific theme or style. Here are two examples of prompts that use effective priming:

1. Creative Writing Priming:
   • Prompt: “You are a futuristic detective in a cyberpunk city. Describe the scene as you walk through the neon-lit streets at midnight, solving a mysterious case.”
   • Priming: The initial instruction sets the context for a creative writing task in the cyberpunk genre. It primes the model to generate responses consistent with the theme of a futuristic detective story, encouraging imaginative and descriptive language.
2. Formal vs. Casual Language Priming:
   • Prompt: “Write a response to a customer asking about a product delay.”
   • Priming: “Write a response to a customer asking about a product delay using a formal and professional tone.”
   • Priming: “Write a response to a customer asking about a product delay using a casual and friendly tone.”

“Ask Before prompting” technique

The “ask before prompting” technique involves initiating a conversation with a Large Language Model (LLM) by first asking it to clarify or seek more information before providing a direct prompt. This method aims to ensure that the model understands the user’s intent more accurately and produces responses that align closely with the user’s expectations.

Example

User: “Can you provide insights into recent advancements in artificial intelligence?  Please ask me any clarifying questions for information you need to provide a better answer.”
LLM: “Certainly! Before I proceed, could you specify any particular area within artificial intelligence you’re interested in, such as natural language processing, computer vision, or machine learning?”

In this example, the user begins with a broad question about recent advancements in artificial intelligence. The LLM responds by seeking clarification on the specific area of interest within AI. The user can then provide more details or specify their focus, allowing the LLM to generate a more targeted and relevant response.

This technique helps to avoid potential misunderstandings or vague responses by encouraging the user to set the context or narrow down the topic before providing a direct prompt. By clarifying the user’s intent early in the conversation, the LLM can better tailor its subsequent responses, resulting in a more effective and focused interaction.
