Different Frameworks in Large Language Models (LLMs)

Abstract LLM models

Introduction

We live in a world where language is at the heart of communication and understanding. From everyday conversations to complex business interactions, the power of language cannot be underestimated. Add to that the complexities of deep learning models trying to understand and generate human languages, and you have another language source. With large language models (LLMs), the boundaries of language processing and generation have been pushed even further.

What are Large Language Models?

Large language models (LLMs) are a revolutionary breakthrough in the field of natural language processing and artificial intelligence. These models are designed to understand, generate, and manipulate human language with an unprecedented level of sophistication. At their core, LLMs are complex neural networks that have been trained on vast amounts of textual data. By leveraging deep learning techniques, these models can capture the intricate patterns and structures inherent in language. LLMs are capable of learning grammar, semantics, and even nuances of expression, allowing them to generate text that closely resembles human-authored content.

The development of LLMs has been a result of continuous advancements in language models over the years. From the early rule-based systems to statistical models and now deep learning approaches, the journey of language models has been marked by significant milestones. The evolution of large language models has been fueled by the availability of massive amounts of text data and computational resources. With each iteration, models have become larger, more powerful, and capable of understanding and generating language with increasing accuracy and complexity. This progress has opened up new possibilities for applications in various domains, from natural language understanding to machine translation and text generation.

Understanding the Capabilities of LLMs

To truly appreciate the capabilities of LLMs, it is essential to delve into their wide range of applications. LLMs can be used for tasks such as:

  1. Language Translation: LLMs excel at translating text from one language to another, providing accurate and contextually relevant translations.
  2. Text Summarization: LLMs can summarize lengthy articles or documents into concise and informative summaries.
  3. Sentiment Analysis: By analyzing text, LLMs can determine the sentiment (positive, negative, or neutral) expressed in a piece of content.
  4. Creative Writing: While limited, LLMs can generate creative content, including poems, stories, and dialogues.

One of the most remarkable features of LLMs is their ability to generate coherent and contextually relevant text. By feeding them a prompt or a partial sentence, LLMs can complete the text in a way that aligns with the given context and adheres to the rules of grammar and style. This opens up exciting possibilities for content creation, automated customer support, and personalized employee experiences.

How Large Language Models Work

Architecture of LLMs

To grasp how Large Language Models (LLMs) operate, it’s important to understand their underlying architecture. LLMs typically follow a transformer-based architecture, which has proven to be highly effective in natural language processing tasks. Key components of this architecture include:

  • Multiple Layers: LLMs consist of multiple layers, including feedforward layers, embedding layers, and attention layers.
  • Attention Mechanisms: LLMs employ attention mechanisms, like self-attention, to weigh the importance of different tokens in a sequence, allowing the model to capture dependencies and relationships.

Types of LLMs

There are different types of large language models, including:

  1. GPT (Generative Pre-trained Transformer): A decoder-only transformer-based model.
  2. BERT (Bidirectional Encoder Representations from Transformers): An encoder-decoder model.
  3. T5 (Text-to-Text Transfer Transformer): An autoencoder model.
  4. Hybrid Models: These combine different architectural components.

In summary, LLMs represent a significant leap in natural language understanding and generation. As research continues, we can expect even more powerful and versatile LLMs to shape the future of language-based AI applications.

WordCamp Ahmedabad 2023

After attending WordCamp Mumbai this year, I decided to keep attending more WordCamps throughout India. As luck would have it, Ahmedabad was just around the corner and I did my booking. WordPress is also used as a quick fix for landing pages in advertising, and hence I thought it would be a good exercise for Harshaja to attend, hoping that she meets some competent (and affordable) WordPress agency to handle the development side of things at 13 Llama‘s end. That, and the super interesting schedule that Ahmedabad had put up.

Getting to Ahmedabad

We chose to take the early morning flight to Ahmedabad. That just meant that the day of the event would be super long for us. Since we hardly knew any folks in the city, this was an easy decision to make. I personally wanted to stay and do some site seeing in this city, but no harm – we could always hop by on one of our annual trips to Vadodara.

The flight was short and getting off the airport and into the cab was one of the smoothest exits we have had. Carrying everything in an overnight handbag does have its advantages!

Venue: Babasaheb Ambedkar Open University

One of the supercool things that struck me during this event was the way Babasaheb Ambedkar Open University (BAOU) was setup. Within a 30 minute drive from the airport, the venue is a sprawling university campus that had access to multiple halls, classrooms, and a great open space where the attendees could congregate in.

I honestly cant imagine the cost of such a large sized venue in Mumbai.

Attendees

We thought that instead of checking-in at the hotel, we would directly attend the event and during the breaks in the afternoon do a quick run to the hotel and finish the checkin process. Thus we directly stopped over at the BAOU campus.

At a little bit earlier than 8am, I was expecting the organizers to be just about gathering and deciding on how they want to execute the rest of the day. To my surprise, there was the beginnings of a crowd already gathering.

What ended up as a small crowd quickly grew to a large congregation, with over 1100 attendees, the WordCamp Ahmedabad 2023 was the second largest WordCamp in Asia, second only to WordCamp Asia!!

I could not help but compare this large audience to what we had in Mumbai. This was more than double the audience of Mumbai and then some!

Talks and Speakers

One thing that always strikes me is that every WordCamp I learn something new. Something that helps me in the future years. Even this time, one of the highlights of the event was the last talk by Nirav Mehta. This one was on public speaking and one of the reasons why I had made sure that the both of us were there to attend.

Some of the other notable talks were on Link Building by an agency owner, Custom Blocks by Amartya Gaur, Yoast’s acquisition by Chaya Oosterbroek. It’s uncanny that even when my functional domain has completely changed, I still took a bunch of learning back from the event!

Ahmedabad, you beauty!

As the day came to an end, I could not help but get overwhelmed with the vibrant PHP developer community that I could see in Ahmedabad. It’s definitely larger and more vocal than the Mumbai community and thus would always be one of the factors for us if we were to open a secondary development office. In fintech, I am seeing more companies shift their technical operations to T2 and T3 cities like Ahmedabad and how!

Nitropack review

Those of you who are running some sort of a content management system (CMS) for your websites would be familiar with the problem of improving the site loading speed through different methods. From the age old caching methods of using op cache module, to using an application specific caching method such as WP-Supercache for your WordPress installations, the sheer variety of solutions out there is a lot.

For a non-tech webmaster (these days, this term seems like a conundrum!), it becomes difficult to choose. At the end of the day, what one ends up going for is how fast the website is loading and more importantly how is the web performance of the site.

Let’s take a look at what are some of the common factors that any webmaster would like at for their caching solution.

Server site rendering time

This is effectively how fast is your server giving the response on the browser. Let’s say that you are running a blog on a small instance or a shared hosting solution. This would usually have limited resources associated with it, be it computing or memory. For instance, currently, these pages are being served off a 512 MB droplet.

Needless to say as your traffic increases, these limited resources are then not enough to address the entire traffic and thus, the response time for all your visitors starts to increase. A simple solution for these problems could be to bump up the hardware and increase the computing and memory being made available for the server. The computing speed is obvious, but why the memory you might ask? Well, since most web servers are softwares running on servers (for e.g Apache or Nginx are the servers most commonly used for WordPress), these software processes have to run on the server. The more the traffic, the more the number of processes.

If you are running WordPress and are facing a load of traffic, and if you are running your database on the same server, then you might sometimes be seeing images like the one below –

MySQL error with WordPress

Seems familiar? A common reason for this is when there are too many apache2 processes and not enough memory to handle all of them. The server promptly terminates the other processes, including the MySQL daemon.

Caching to the rescue

This is where server side caching comes to the rescue. Take this blog post for instance. How many times in the week am I going to edit this? Not many right?

In which case, instead of the PHP script executing every time, why can I not serve the static (HTML pre-rendered) version of this post?

WP-Supercache does a good job as a plugin to do this, however, in this case, for supercache to execute, the WordPress PHP scripts are still executing. How can we stop those?

Another option would be to run caching at Apache or Nginx’s level. This is a much better approach since instead of calling PHP scripts, the server will serve the last known cached static file. The problem with this approach is cache management and storage.

With a small server, you may not have a lot of storage, and if you have been maintaining a content heavy site, then caching all pages might be a storage intensive process. The expectation from your instance’s compute power also increases.

This is where you will find reverse proxy servers shining.

Reverse proxy servers

A reverse proxy server is a server that sits in front of the web servers and forwards client requests. One of the older versions for PHP based websites was Varnish. Nginx also offers this, and newer versions of Apache also do offer this functionality.

What the reverse proxy does is for each request, it caches the response from the down stream server and serves that response for each subsequent request. Think of it as a smart cache manager that sites seamlessly between your CMS and the user.

Traditionally, these were a bit difficult to setup, and therefore were the domain of only the tech oriented webmasters. However, of late, there have been a couple of smart SasS based reverse proxies, and that’s what I wanted to write about.

Cloud-based reverse proxies

A cloud based reverse proxy is a reverse proxy server that’s not on your network/server infrastructure, but rather hosted as a separate service that you choose to buy.

I had initially tried Cloudflare, but wasn’t really impressed with the results. There were a couple of Indian service providers as well, but the outcome wasn’t that great.

Then, one of my colleagues pointed me to Nitropack. Getting started with Nitropack was a breeze and I could easily set this up. There was also a plugin to be installed in my WordPress setup and that’s about it. Nitropack even had a CloudFlare integration (since I manage my DNS on CloudFlare), where it made the relevent DNS entries and I was able to use this without too much of a hassle.

I am currently on the free plan, but the immediate impact on my server response times, and my web performance has been substantial.

If you are a website owner and if you have been harangued with web performance issues, do give this solution a try. It makes a sufficient impact on your response times.

My first Ionic App

The couple of Phonegap apps that I worked on, things were too messed up.

  1. Is it Phonegap or is it Cordova?
  2. Do I build locally or do I used Phonegap Build?
  3. Using jQuery Mobile, which event happens first – device ready or jquery ready?
  4. Why is this too slow?

There were times, when I felt that I had absolutely no control on the app. This is where my frustrations with Phonegap started growing … not to mention the insane compile complications.

Enter Ionic

This is where I first learn about the Cordova project and how there are multiple spin-offs of that. Phonegap being just one of those … I always assumed that PG and Cordova were synonyms. Guess not.

To start with Ionic, the getting started guide to Ionic is a pretty decent place to start. Keep in mind though that it’s best that you go through some basic Angular tutorials before you dive into Ionic.

Enter Angular

The thing about javascript based apps is that you need a javascript library to run the app on. You could arguably use native JS methods and create your own bespoke app.

But that’s not really a wise choice (unless you are a freaky javascript ninja). I don’t know about you, but I for certain am not. Let me at those libraries!

This is where jqm or angular really matter. My experience with jqm was pretty bad and although I am liking angular, things seem far more in my control.

Who really owns the code?

At 13 Llama Studio, we have no qualms of handing over the code base and giving away the ownership of the code to the client. The way I figure it is this –

Since most of the work we do is based on derivative works under the GPL license, the source code by default needs to be included as part of the deliverable. Yes, we build multiple interesting things with WordPress, but WordPress as a platform is under GPL.

Rise of the App Economy

As a technical architect and a start-up enthusiast, part of my work is consulting organizations on how to go about implementing and monetizing their ideas. The past decade’s experience of working in this field, as well as having successfully built the product and development teams of two start-ups (which secured VC fundings) ensures that a lot of people are willing to share their ideas so that I can advise them on the implementation.
