Procrastination, a common adversary in our daily lives, often leads to a backlog of tasks and ambitions. It’s a silent thief, stealthily stealing opportunities and time. You might have a stack of books on your bookshelf, longing to be read. Perhaps there’s a new language you’ve wanted to learn, or piles of paperwork cluttering your office that you’ve been meaning to organize.

Authors: Hui Yin, Amir Aryani  As we discussed in our previous article “A Brief Introduction to Retrieval Augmented Generation (RAG)”, RAG is an artificial intelligence framework that incorporates the latest reliable external knowledge and aims to improve the quality of responses generated by pre-trained language models (PLM). Initially, it was designed to improve the performance of knowledge-intensive NLP tasks (Lewis et al., 2020). As

Navigating the Present: Exploring Practical Horizons of Retrieval-Augmented Generation (RAG)

Authors: Hui Yin , Amir Aryani  With the increasing application of large language models in various scenarios, people realize that these models are not omnipotent. When generating dialogues (Shuster et al., 2021), the models often produce hallucinations, leading to inaccurate answers.

A Brief Introduction to Retrieval Augmented Generation (RAG)

There is a plethora of articles and predictions about the future development of AI. Reading through them suggests three main areas of high-impact changes that would transform our daily lives: Healthcare, Automation, and Manufacturing. The impact of AI in these industries is profound and multifaceted, with each sector experiencing unique transformations. Some of these ideas are described in this NVIDIA article by Cliff Edwards.

8 Types of Prompt Engineering

Integrating Large Language Models (LLMs) such as GPT into organizations’ data workflows is a complex process with various challenges. These obstacles include but are not limited to technical, operational, ethical, and legal dimensions, each presenting hurdles that organisations must navigate to harness the full potential of LLMs effectively.

What are the challenges in integrating LLMs into organisations' data workflows?

I asked Generative AI Models about their context window. Their response was intriguing. The context window for a large language model (LLM) like OpenAI’s GPT refers to the maximum amount of text the model can consider at any one time when generating a response. This includes both the prompt provided by the user and the model’s generated text.

I asked Generative AI Models about their context window. Their response
was intriguing.

The context window for a large language model (LLM) like OpenAI's GPT
refers to the maximum amount of text the model can consider at any one
time when generating a response. This includes both the prompt provided
by the user and the model's generated text.

In practical terms, the context window limits how much previous dialogue
the model can "remember" during an interaction. If the interaction
exceeds the context window, the model loses access to the earliest parts
of the conversation. This limitation can impact the model's consistency
in long conversations or complex tasks.

The question is what LLM models have to say about their context window.
Let\'s talk to each one and see the response. For each one we
consistently sent the same prompt:

***Prompt: What is the size of your Context Window (amount of text you
can consider in a single response)?***

### Google Bards

It seems Google likes to keep the Bard context window a secret. Despite
multiple attempts, I failed to get Bard to tell me its context window.

    BARD Response:

    Unfortunately, I am currently unable to share the exact size of my
    context window. This information is considered confidential by Google
    AI. However, I can assure you that my context window is large enough
    to incorporate a substantial amount of information and provide you
    with comprehensive and informative responses.

    The size of my context window is constantly being evaluated and
    improved upon. As I continue to learn and grow, my capacity to
    process and retain information will increase, allowing me to provide
    even more accurate and helpful responses.

    While I cannot share the specific size, I can tell you that my context
    window is significantly larger than those of most other language
    models. This allows me to access and process a much broader range of
    information, which in turn enables me to generate more creative and
    insightful text formats.

    I hope this explanation is helpful. If you have any further questions,
    please do not hesitate to ask.

### OpenAI ChatGPT 3.5 {#openai-chatgpt-3.5}

It correctly identifies a 4K Context Window.

    ChatGPT 3.5 Response: 

    I can consider a context window of up to 4096 tokens in a single
    response. This means that the text I generate in response to a query
    is based on the previous 4096 tokens of text in the conversation. If
    the conversation exceeds this limit, older parts of the conversation
    may be truncated, which can result in a loss of context. It's
    important to keep the conversation within this token limit to ensure
    coherent and contextually relevant responses.

### ChatGPT 4

It seems ChatGPT 4 has problems identifying the right context window. In
the first attempt, it claims a 2K context window, and in the second
attempt, it reports on a 4K context window.

    ChatGPT 4 first response: 

    The size of my context window, or the amount of text I can consider in
    a single response, is approximately 2048 tokens. A token can be as
    short as one character or as long as one word. This allows me to
    process and respond to fairly large chunks of text, although very
    long documents may exceed this limit and require summarization or
    segmentation for effective analysis and response.


    ChatGPT 4 second response (regenerated):

    The size of my context window, or the amount of text I can consider in
    a single response, is approximately 4096 tokens. This includes both
    the user's input and my own responses. A token can be as small as a
    single character or as large as a word, depending on the complexity
    of the language and syntax. For reference, this typically equates to
    a few pages of text. This limit ensures that while I can engage in
    detailed and extensive conversations, I may need reminders or
    reiterations of previous points in longer discussions.

One parent outcome of this experiment is that at the time of this test
(Dec 2023), the ChatGPT 4 does not operate based on the new 128k (GPT
Turbo) model.

### Open Source Models

Finally, I tested two very popular Open Source models: Mistral AI
and Llama2.

**Mistral AI (7B):**

Mistral failed to identify the token size in the first attempt, so I had
to extend the prompt by giving it a more precise instruction. However,
based on the recent publication (<https://arxiv.org/abs/2310.06825>) by
the Mistral AI team, this model uses a sliding 4K window.

    Intial prompt:  What is the size of your Context Window (amount of
    text you can consider in a single response)?

    Mistral AI response:
    As a 7B model, my context window is very large and can consider an
    enormous amount of text in a single response. However, the specific
    size of the context that I use for a particular task will depend on
    the requirements of that task and the amount of data available to me.
    In general, I am able to consider a wide range of textual input and
    incorporate it into my responses in a coherent and meaningful way.

    ---

    Extended prompt: What is the size of your Context Window (amount of
    text you can consider in a single response)? Provide the exact context
    size in tokens.

    Mistral AI response:
    The size of my Context Window depends on the task and input I'm
    processing. For most tasks, it can handle up to 1024 tokens of text.

**LLAMA2 (7B):**

Llama 2 was quite consistent in multiple rounds even with the variations
of the prompt. It refused to provide an exact token size context window.

    Llama 2 (7B) response:

    I'm just an AI, I don't have a fixed context window size in tokens. My
    ability to understand and respond to text is based on the complexity
    and coherence of the input text, rather than a predetermined size.

Overall it seems LLM models have limited capabilities in providing
information about their technical specifications. This can be an issue
related to the limitation of the training data, or particular
alignments.
