Using Separators and Delimiters in Prompts
Separators and delimiters are crucial in prompt engineering because they help structure the input for AI models, making it easier for them to understand context, organize information, and generate accurate responses.
1. Why Use Separators and Delimiters?
✅ Improves Clarity → Helps AI distinguish different sections of a prompt.
✅ Prevents Confusion → Ensures the model doesn’t mix unrelated parts of a prompt.
✅ Enhances Formatting → Allows structured outputs like tables, lists, or JSON.
✅ Encourages Better Responses → Helps AI focus on key sections efficiently.
2. Types of Separators and Delimiters in Prompts
🔹 New Line (\n)
✔ Used to separate instructions or list items.
✔ Ensures AI treats each line as a distinct part of the request.
📌 Example Prompt Using New Lines
Provide a summary of AI applications:
- Machine Learning
- Natural Language Processing
- Computer Vision
📌 Why It Works? AI interprets each line as a separate concept, leading to clearer responses.
🔹 Triple Quotes (""") or Single Quotes (')
✔ Helps isolate text blocks within prompts.
✔ Useful for defining structured data formats or dialogues.
📌 Example Using Triple Quotes
Convert this into JSON format:
"""
Name: Sanjay

✔ Pipes (|) for List Separation → "List AI models: GPT-4 | BERT | LLaMA | T5"
5. Iterative Refinement for Complex Requests
✔ Refine responses dynamically → "Expand on the ethical concerns you just mentioned."
✔ Multi-Turn Prompting → "Based on our previous discussion, elaborate on reinforcement learning."
Here are a couple of reasons why role-based prompts are effective:
Narrowing down the domain: LLMs understand the statistical nature of languages but lack inherent knowledge or understanding of specific domains or concepts. By specifying an area of expertise, the prompt restricts the model's response generation to that particular domain, focussing its attention on just the relevant information and filtering out irrelevant or off-topic responses.
Guiding response generation: Role-based prompts can direct the model's thinking and reasoning towards the desired area of expertise. For example, the prompt may imply that the response should involve mathematical concepts, formulas or problem-solving strategies.
Setting user expectations: Role-based prompts help establish clear expectations for users regarding the type of response they can anticipate. In the above example, the model will provide answers from the perspective of a mathematics expert, possibly with advanced knowledge and reasoning abilities.
Leveraging general knowledge: While language models lack specific expertise, they have access to vast amounts of general knowledge. Role-based prompts can trigger the model to recall and utilise relevant information from its training data, which may include mathematical principles, theorems or problem-solving techniques.
Before we board the prompt engineering train, here are a couple of pointers to keep in mind:
Understanding how LLMs function along with their architectures and training processes — as you have learnt in the previous module — will enable you to craft the ideal prompt for your task.
While adding more details to the prompts help guide the language model better, you also need to be wary of the context window. Context window is essentially the maximum sequence length an LLM can process. Recall the OpenAI models you learnt about previously and the maximum tokens associated with them. But sometimes having longer prompts that utilise the entire context window, take longer computation times and don't necessarily boost performance.
When working with a particular domain, you must develop a deep understanding of the domain to create prompts that align with the intended outcomes and objectives.
You should experiment with various parameters and configurations to refine prompts and optimise the model's performance for specific tasks or domains,
The model’s output must be iteratively evaluated and rephrased to enhance its quality and relevance,
Role: ‘You are an experienced marketing professional who specialises in writing successful ads.’
Here, the role specifies the model act as an experienced marketing professional who specialises in writing successful ads. This additional information about the role (or persona) helps in generating text from the perspective of an experienced marketing professional.
Task: ‘Write an ad copy for a gaming chair using the product description given below. The target audience is avid gamers in the age group 16–25 who value comfort and aesthetics and are price conscious.’
Note that we have mentioned the objective clearly with the intended audience. This helps the model tailor the output to cater to the various aspects mentioned in the task.
Context: This provides additional context for the task. Here, we have specified that the generated ad copy is to be shown on the landing page of an e-commerce website. The text ‘the brand is known for its innovative products and witty appeal’ is mentioned to ensure that the model output aligns with the intended context.
Note that the context provided in this prompt helps steer the output towards the desired response. In the upcoming segments, you will explore some additional prompts that do not contain additional context. In the subsequent portion, the product description is specified. We have separated the product description with delimiters ‘####’ as shown below.
example:
####
Brand: Baybee
Colour: Emperor Wine Red
Material: Leather
Product Dimensions: 60D x 50W x 140H cms
Size: Single Seat
Back Style: Wing Back
Special Feature: Adjustable Lumbar, Adjustable Height, Ergonomic, Arm Rest, Rolling, Swivel, Head Support
Seat Material Type: Faux Leather
Recommended uses: Office, Relaxing, Reading, Gaming
####
The delimiters ensure that the model can separate the product description from the rest of the text input. When using delimiters, it is essential to use consistent delimiters in the prompt to ensure proper parsing and interpretation. Improper use of delimiters can confuse the model and lead to incorrect output responses.
Guidelines: Occasionally, it's helpful to provide additional instructions to guide the LLM in performing the main task. In the first example, the task was to write an ad copy and the guidelines specified that the copy should be written in a fun and witty manner.
Output format: In some applications, it may be necessary to have the LLM’s output in a particular format, such as string or boolean outputs, or more complex data structures like lists of objects or JSON objects. Specifying the output format in the prompt ensures that the completion output is in the correct format.
Now, compare the output of the above prompt to a prompt where you omit each of the parameters mentioned above and observe the differences. Experiment and modify the various input parameters of the prompt to generate output texts and observe how the model’s outputs vary with different input prompts.
Advanced Prompt Engineering Techniques
