What is a LLM?

A Large Language Model (LLM) AI is a form of artificial intelligence program capable of recognizing and generating text, among various other tasks. LLMs derive their name from being trained on extensive datasets, earning the “large” descriptor. These models operate on machine learning principles, specifically utilizing a neural network known as a transformer model.

In simpler terms, an LLM is a computer program exposed to sufficient examples to recognize and interpret human language or other complex data. Many LLMs undergo training using vast amounts of data sourced from the Internet, often totaling thousands or millions of gigabytes of text. The quality of these samples significantly influences how well LLMs learn natural language, prompting some programmers to opt for more carefully curated datasets.

Utilizing deep learning, a subset of machine learning, LLMs grasp the interactions among characters, words, and sentences. Deep learning involves probabilistic analysis of unstructured data, enabling the model to discern distinctions between content pieces without human intervention.

LLMs undergo additional training through a process known as tuning. This involves fine-tuning or prompt-tuning, tailoring the model to the specific task desired by the programmer—whether it be interpreting questions, generating responses, or translating text between languages.

Great! Let’s get started on the blog post about large language models.


Let’s take a journey through the fascinating history of Large Language Models (LLMs). It all began back in ancient times when people meticulously recorded their knowledge on papyrus scrolls, stored in the renowned Library of Alexandria.

What are LLMs used for?

LLMs exhibit versatility in their ability to be trained for various tasks. One prominent application is as generative AI, where, prompted or queried, they can generate text responses. An example is the publicly accessible LLM ChatGPT, capable of producing essays, poems, and other textual content in reaction to user inputs.

These models can be trained on diverse and intricate datasets, encompassing programming languages. Some LLMs assist programmers by generating code. They can create functions upon request or, starting with existing code, complete the writing of a program. LLMs find application in several areas, including:

  1. Sentiment analysis
  2. DNA research
  3. Customer service
  4. Chatbots
  5. Online search

Real-world instances of LLMs include ChatGPT (OpenAI), Bard (Google), Llama (Meta), and Bing Chat (Microsoft).

What are some advantages and limitations of LLMs?

A distinctive feature of LLMs is their capability to respond to unpredictable queries, setting them apart from traditional computer programs. Unlike programs with predefined syntax or limited user inputs, LLMs can interpret and respond to natural human language, providing meaningful answers to unstructured questions or prompts. While conventional programs might struggle with a prompt like “What are the four greatest funk bands in history?” an LLM can generate a list along with a coherent defense of its choices.

However, the reliability of information provided by LLMs depends on the quality of the data they are trained on. If fed inaccurate information, they may produce misleading responses to user queries. LLMs may also “hallucinate,” creating fictional information when faced with challenges in producing accurate answers. For instance, in 2022, when asked about Tesla’s previous financial quarter, ChatGPT generated a coherent news article with invented information.

In terms of security, user-facing applications based on LLMs are susceptible to bugs like any other application. LLMs can be manipulated through malicious inputs to generate specific responses, potentially posing risks that are dangerous or unethical. Moreover, a security concern with LLMs involves users uploading secure, confidential data to enhance productivity. However, LLMs use these inputs to train their models and are not designed as secure vaults, potentially exposing confidential data when queried by other users.

How do LLMs work?

Machine learning serves as the foundational framework for Large Language Models (LLMs). Operating within the broader field of artificial intelligence (AI), machine learning involves training a program by exposing it to substantial data to autonomously identify features without direct human intervention.

LLMs specifically employ a form of machine learning known as deep learning. Deep learning models possess the ability to self-train and recognize distinctions without continual human intervention, although some fine-tuning by humans is usually required.

Deep learning relies on probability to “learn.” For example, in the sentence “The quick brown fox jumped over the lazy dog,” the letters “e” and “o” are the most common, occurring four times each. A deep learning model could correctly infer that these characters are likely to appear frequently in English-language text.

To facilitate deep learning, LLMs are constructed on artificial neural networks, akin to the interconnected neurons in the human brain. These artificial neural networks, or “neural networks,” consist of layers, including an input layer, an output layer, and one or more intermediary layers. Information is transferred between layers only if their outputs surpass a certain threshold.

The specific type of neural networks utilized in LLMs is known as transformer models. Transformer models excel at learning context, crucial for understanding human language’s context-dependent nature. Employing a mathematical technique called self-attention, transformer models detect subtle relationships within a sequence, enhancing their ability to comprehend context compared to other machine learning approaches. This capability allows LLMs to interpret human language, even in instances of vagueness, novel combinations, or new contextual frameworks. LLMs showcase a degree of “understanding” semantics, associating words and concepts by meaning, derived from exposure to millions or billions of instances where they are grouped together.

How developers can quickly start building their own LLMs
