Large Language Models, better known as LLMs, are at the forefront of the ongoing Artificial Intelligence (AI) revolution that is transforming the world of technology. Popular representatives of AI such as OpenAI's ChatGPT and Google's Bard also deploy this astonishing technology, and the term "LLM" is mentioned constantly in discussions, events and keynotes. So, what exactly is an LLM? Let’s explore!

Large Language Models are a type of AI program, and to be more precise, a type of Machine Learning (ML) program. It is built on a neural network model known as transformer model. The model is fed large amounts of data, usually from well curated data sources and datasets found on the internet, and then trained to interpret diverse and complex types of data (including human language). Following this, Deep Learning (DL) is deployed to conduct an analysis of this unstructured data to distinguish between different pieces of input and research data. Through this process, LLMs are able to generate appropriate responses for any problem that they are presented with. 

LLM models are best used as a form of Generative AI (GenAI). GenAI can generate text-based responses to all kinds of problems and even write complex code in a matter of seconds! It also has several other applications such as sentiment analysis, customer service etc. As a technology it is still in its early stages, comprising of several key issues such as bugs and other types of manipulations. Regardless, LLMs are the next big thing in AI today, and are sure to become a staple of tomorrow.
