From shaping stories to simplifying complex articles to engaging in conversations that feel genuinely human, large language models (LLMs) are driving a new era of AI.
In this article, we share our decade-long experience as an AI software development firm and dive into the world of LLMs, unraveling their innards and exploring how they’re reshaping the future of artificial intelligence.
Let’s kick it off with the basics: what are large language models?
A large language model is an algorithm trained to recognize, summarize, translate, predict, and generate any form of text.
How do LLMs differ from traditional language models?
Large language models fall under the umbrella of deep learning algorithms known as transformer neural networks. It is the transformer architecture that helped surpass the limitations of traditional language models that have been around for years.
Traditional language models operated in a sequential manner, processing one word (or character) at a time and delivering an output once the entire input text had been consumed. While quite functional, these models had a notable flaw: they used to “forget” the beginning of a sequence by the time they reached the end.
It all changed in 2014 when the attention mechanism was first introduced that was later popularized by Google. The attention mechanism enabled a paradigm shift from sequential processing, allowing a transformer model to perceive the entire sequence simultaneously.
This revolutionized the machines’ understanding of context. By embracing the entirety of the input at once, the transformer model gains the ability to comprehend the nuances and complex relationships among words in a text.
How do LLMs work under the hood?
Large language models learn from data.
The datasets used to train LLMs are massive. For example, OpenAI’s well-known and much loved GPT4 is believed to have been trained on about 13 trillion tokens (think: basic units of text that a model can process.)
The model gradually learns words, the concepts behind them, and the relationships between. Once a model has learned enough, it can transfer its “knowledge” to solving more complex problems, like predicting and generating text.
It is possible thanks to a two-component transformer architecture consisting of an encoder and a decoder:
In the picture, “shifted right,” means that during the generation of each token in the output sequence, the model considers the previously generated tokens (that are “situated” to the left) as context. So, the model “looks back” at the tokens it has already generated to determine the next token in the sequence. Image source: ITRex
Once an input text is fed into a model, it is converted into tokens that can be parts of words, entire words, parts of sentence, or full sentences. The tokens are then converted into vector-space representations that preserve the initial token meaning.
The encoder structures these representations, picking out important details and creating a context vector based on that. So, the context vector holds the essence of the entire input text.
Based on the initial output and relying on the context vector, the decoder generates a coherent output, say, picking out the most suitable word to finish a sentence. By repeating this process, a transformer model can generate the entire passage word by word.
Due to this extensive training process, LLMs are not limited to performing any specific task and can serve multiple use cases. These types of models are also referred to as foundation models. However, you can fine-tune the foundation models to perform a narrow task by feeding them small bits of data to focus on.
How are large language models used in business?
Large language models are proving to be valuable assets across sectors. Here are just a few use cases to give you an idea of what LLMs are capable of.

LLMs are driving the evolution of customer service and engagement. Chatbots and virtual assistants powered by LLMs can handle complex inquiries, provide personalized recommendations, and engage in human-like conversations, enhancing user experiences and operational efficiency.
Energy companies, like Essent, deal with a consistent influx of customer service demands. Jeroen Roes, lead conversational AI program manager at Esse nt, says that the company had relied on telephony as its primary customer service tool for decades. However, in the face of intensifying competition and a surge in customer service requests, Essent recognized the need to reinvent its operations to maintain a competitive edge.
The company saw an opportunity in LLM-based chatbots. By harnessing this innovative technology, Essent managed to meet the growing customer service needs.
2. Sentiment analysis, market research, and trend prediction
Businesses are leveraging LLMs for sentiment analysis to gauge public opinion, track brand perception, and predict market trends. By analyzing vast datasets, LLMs help businesses make informed decisions, optimize marketing strategies, and stay ahead of the competition.
For example, Sprinklr, a social media management and customer engagement platform, harnesses large language models for sentiment analysis. This assists businesses in monitoring and engaging with discussions related to their brand or product on social media. Sprinklr’s platform analyzes social media data to identify sentiment patterns and provide valuable insights into customer behavior and preferences.
3. Content generation

Adopting LLMs for business: factors to consider
Incorporating large language models into your business operations is a strategic move that can yield significant benefits. However, it’s crucial to navigate this transformation thoughtfully and meticulously. Here, we delve into the essential factors you should consider when adopting LLMs for your enterprise.
1. Available infrastructure and resources
LLMs are hungry for processing power, so they require a robust infrastructure. Before diving in, assess your current IT infrastructure and determine if it can accommodate the substantial computational demands of LLMs, or if an upgrade or expansion is necessary.
Also, keep in mind that LLMs can be resource-intensive. As your business grows and your reliance on LLMs increases, scalability becomes pivotal. Ensure that your infrastructure is not just suitable for current needs but can also adapt to future ones. Scalability might involve adding more powerful servers, utilizing cloud-based solutions, or a combination of both.
2. Choose whether to go open-source or custom
There are two common ways to adopt LLMs: fine-tune an open-source model or train a custom one. Your choice should align with your business objectives.
Open-source models, like GPT-3,5, offer a cost-effective entry point for experimenting with AI-powered applications.
