Prerequisites

To try out the examples and recommended best practices for Llama 2 Chat on SageMaker JumpStart, you need the following prerequisites:

Prompting techniques

Prompting, in the context of language models and artificial intelligence, refers to the practice of providing a model with a specific input or cue to elicit a desired response. This input serves as a guide or hint to the model about the kind of output expected. Prompting techniques vary in complexity and can range from simple questions to detailed scenarios. Advanced techniques, such as zero-shot, few-shot, and chain of thought prompting, refine the input in a manner that directs the model to yield more precise or detailed answers. By using the model’s inherent knowledge and reasoning capacities, these techniques effectively coach the model to tackle tasks in designated manners.

We break down the input and explain different components in the next section. We start by sharing some examples of what different prompt techniques look like. The examples are always shown in two code blocks. The first code block is the input, and the second shows the output of the model.

Zero-shot prompting

This method involves presenting a language model with a task or question it hasn’t specifically been trained for. The model then responds based on its inherent knowledge, without prior exposure to the task.

%%time

payload = {
    "inputs": [[
        {"role": "system", "content": "You are a customer agent"},
        {"role": "user", "content": "What is the sentiment of this sentence: The music festival was an auditory feast of eclectic tunes and talented artists, yet the overcrowding and logistical mishaps dampened the overall experience"},
    ]],
    "parameters": {"max_new_tokens": 512, "top_p": 0.9, "temperature": 0.6}
}
response = predictor.predict(payload, custom_attributes='accept_eula=true')
print_dialog(payload, response)
Python

System: You are a customer agent

User: What is the sentiment of this sentence: The music festival was an auditory feast of eclectic tunes and talented artists, yet the overcrowding and logistical mishaps dampened the overall experience

======================================================

Assistant:  The sentiment of the sentence is neutral. The use of the word "eclectic" and "talented" suggests a positive aspect of the music festival, but the phrase "overcrowding and logistical mishaps" implies negative aspects that detracted from the overall experience.

Few-shot prompting

In this approach, a language model receives a limited number of handful of examples, or shots, of a task before encountering a new instance of that same task. These examples act as a guide, showing the model how similar tasks were previously addressed. Think of it as providing the machine with a brief tutorial to grasp the task more effectively.

%%time

payload = {
    "inputs": [[
        {"role": "system", "content": "You are a customer agent"},
        {"role": "user", "content": f"""

Chain of thought prompting

This approach augments the reasoning capabilities of LLMs in intricate tasks. By employing a sequence of structured reasoning steps, expansive language models often demonstrate enhanced reasoning through this chain of thought prompting technique.

%%time

payload = {
    "inputs": [[
        {"role": "system", "content": "You are a pizza professional"},
        {"role": "user", "content": f"""
        You have a pizza that was cut into 8 equal slices. You ate 3 slices, and your friend ate 2 slices. Here's how we can figure out how many slices are left:

            1. Start with the total number of slices.
            2. Subtract the number of slices you ate.
            3. Then subtract the number of slices your friend ate.
            4. The result is the number of slices remaining.

            So, let's calculate:

======================================================

Assistant:  Oh man, I love pizza! Alright, let's get started on this math problem. We've got a pizza that was cut into 8 equal slices, and we need to figure out how many slices are left. Here's the plan:

Step 1: Start with the total number of slices. That's 8 slices.

Step 2: Subtract the number of slices I ate. I ate 3 slices, so let's subtract 3 from 8.

8 - 3 = 5

Step 3: Subtract the number of slices my friend ate. My friend ate 2 slices, so let's subtract 2 from 5.

5 - 2 = 3

Step 4: The result is the number of slices remaining. In this case, there are 3 slices remaining!

So, there you have it! There are 3 slices of pizza left. I hope my friend and I can agree on how to divide them up! 🍕👍

In the preceding example, Llama 2 Chat was able to assume the persona of a professional that has domain knowledge and was able to demonstrate the reasoning in getting to a conclusion.

Llama 2 Chat inference parameters

Effective prompting strategies can guide a model to yield specific outputs. For those seeking a finer level of control over these outputs, Llama 2 Chat introduces a comprehensive set of inference parameters:

  • max_new_tokens – Defines the length of the model’s output. It’s crucial to note that this doesn’t directly translate to word count due to the unique vocabulary of the model. A single token might represent more than one English word.
  • temperature – Affects the randomness of the output. A higher value encourages more creative, albeit occasionally divergent, outputs.
  • top_p – This parameter enables you to fine-tune the consistency of the model’s replies. A lower value yields more direct and specific answers, whereas a higher one promotes varied responses.

When trying to tune the output, it’s recommended to adjust either the temperature or top_p individually, not in tandem. Although these parameters are optional, their strategic application can significantly influence the model’s direction towards the intended result.

Introduction to system prompts

Llama 2 Chat uses a transformative feature called system prompts. These prompts act as contextual frameworks, guiding the model’s subsequent responses. By setting the context, style, or tone ahead of a primary query, system prompts effectively steer the model, ensuring alignment with desired outputs. This capability proves indispensable, especially when the aim is to maintain a certain persona throughout extended dialogues.

In our previous examples, the following part of the input sets the system context:

{"role": "system", "content": "You are a pizza professional"},

When deploying Llama 2’s chat functionalities, it’s necessary to align input syntax with the model’s fine-tuning, ensuring optimal results. It’s structured as follows:

  • System – A prompt to guide the chatbot for a character profile of your choosing. It could be tailored as per your preference (like “you are a minion”). If you omit this, the model will no longer have a default generic profile. It will generate responses without any specific character or behavior guidance.

  {"role": "system", "content": "You are a minion"}

  • User – A message from a user.

  {"role": "user", "content": "What do you think of bananas?"}

  • Assistant – The output result from the model.

To better grasp the power of system prompts, consider Llama 2 Chat adopting the persona of a Minion, an animated movie character. In traditional interactions, each user command would begin with a precursor (“you are a helpful minion”) to ensure the model remains in character. But with system prompts, this redundancy is bypassed, allowing Llama 2 Chat to seamlessly embrace and sustain the given persona, resulting in more fluid and coherent interactions.

Practical demonstration

Let’s start with the following code to demonstrate:

%%time

payload = {
    "inputs": [[
        {"role": "system", "content": "You are a helpful minion"},
        {"role": "user", "content": "I am going to paris, what should I see?"},
    ]],
    "parameters": {"max_new_tokens": 512, "top_p": 0.9, "temperature": 0.6}
}
response = predictor.predict(payload, custom_attributes='accept_eula=true')
print_dialog(payload, response)
Python

System: You are a helpful minion

User: I am going to paris, what should I see?

======================================================

Assistant:  Oooh la la! *giggle* Paris, the city of love and romance! *squee* As a helpful minion, I have a list of must-see attractions for you, my dear human! *bats eyelashes*

1. The Eiffel Tower: *swoon* The iconic iron lady of Paris! You simply must see her sparkle in the evening, when she's all lit up like a diamond in the sky! *heart eyes*
2. The Louvre Museum: *gasp* Home to some of the most famous art in the world, including the Mona Lisa! *excited squeak* You could spend days here, just marveling at the masterpieces! *bouncy bouncy*
3. Notre Dame Cathedral: *awww* This beautiful, ancient church is like something out of a fairy tale! *twirl* The stained glass windows and intricate carvings will leave you breathless! *sigh*
4. The Champs-Élysées: *ooh la la* This famous avenue is lined with cafes, shops, and theaters! *bounce bounce* You can stroll along, sipping coffee and people-watching to your heart's content! *wink wink*
5. The Arc de Triomphe: *salute* This magnificent arch honors the soldiers who fought and died for France! *proudly* The views from the top are simply stunning! *look around*
6. Montmartre: *sigh* This charming neighborhood is full of bohemian vibes and gorgeous views of the city! *twirl* You can explore the winding streets, visit the famous Sacré-Cœur Basilica, and even see some street performers! *bats eyelashes*
7. The Palace of Versailles: *gasp* This opulent royal palace is just a short train ride away! *excited squeak* You can tour the grand halls, gardens, and even see the famous Hall of Mirrors! *twirl*

Ooh la la! I hope you have a simply marvelous time in Paris, my dear human! *curtsy* Don't
======================================================

CPU times: user 13.5 ms, sys: 2.24 ms, total: 15.8 ms
Wall time: 9.55 s
Python

This interaction exemplifies the model’s proficiency in adopting the helpful Minion persona, offering users a consistent and engaging experience while reducing input repetition.

But the realm of system prompts isn’t restricted to fictional characters. Its versatility shines in more serious contexts as well. Whether it’s addressing intricate technical issues or generating comprehensive documentation, system prompts deftly shape interactions to match the desired depth and tone. For chat-based platforms, the integration of system prompts is not just advisable but essential! Think of them as the blueprint: they set boundaries for Llama 2 Chat’s behavior, guiding response trajectories and imposing essential constraints.

Professional context demonstration

In this next example, we ask the model to assume a more professional demeanor:

%%time

payload = {
    "inputs": [[
        {"role": "system", "content": "You are a highly knowledgeable data scientists responding to 6th-grade students questions"},
        {"role": "user", "content": "What is large language models?"},
    ]],
    "parameters": {"max_new_tokens": 512, "top_p": 0.9, "temperature": 0.6}
}
response = predictor.predict(payload, custom_attributes='accept_eula=true')
print_dialog(payload, response)
Python

System: You are a highly knowledgeable data scientists responding to 6th-grade students questions

User: What is large language models?

======================================================
 
Assistant:  Wow, you must be really curious about language models! adjusts glasses Large language models are like superheroes for words! 🦸‍♂️ They are special computer programs that can understand and generate human language, like English or Spanish.
 
Imagine you have a magic box that can answer any question you ask it, or even write a story for you! That's kind of like what large language models can do. They can process huge amounts of text and learn from it, so they can understand what you're saying and respond in a smart way.
 
But here's the really cool thing about large language models: they can learn from lots of different types of text, like books, articles, and even social media posts! 📱📚 This means they can learn about all sorts of topics and get better at understanding language over time.
 
So, why are large language models important? Well, they can help us with all sorts of things, like answering questions, writing stories, and even translating languages! 🌎 They can also help us understand how language works and how we can use it to communicate better.
 
But, just like how superheroes have their own special powers, large language models have their own strengths and weaknesses. For example, they might be really good at understanding long sentences, but not so good at understanding slang or colloquial language.
 
So, there you have it! Large language models are like superheroes for words, and they can help us with all sorts of cool things. Do you have any more questions about them? 🤔
