The Basics of Large Language Models

In recent months, large language models (LLMs) have been a topic of conversation for everyone from business leaders to high school students, and for good reason. That’s because this technology has witnessed unprecedented growth. Just this past January, there was record-breaking growth of ChatGPT's user base. Combine that with the introduction of Google’s model Bard, in Feb 2023 and it’s safe to say that LLMs are here to stay. 

Large language models have unlocked new possibilities for businesses by automating processes, driving personalization, increasing accuracy in tasks, and ultimately saving time and money. However, large language models are still a relatively novel concept in computer science, which may make it difficult for business leaders to stay updated on their potential applications. In this blog post, we’ll provide a basic understanding of LLM’s along with a glossary of terms, phrases, and concepts that we hope you’ll find useful. Want to learn more about ai technology?

What are Large Language Models? 

Large language models are a type of artificial intelligence (AI) system that can generate text that is similar in style and content to human-written text. These models use deep learning techniques, specifically neural networks, to analyze and generate text. 

The term "large" in "large language model" refers to the vast amounts of data and computing resources required to train these models. Training a large language model requires feeding the neural network with massive amounts of text data, typically hundreds of billions of words or more. This data is used to train the model to recognize patterns and relationships in language, such as word meanings, sentence structure, and grammar. 

Once trained, a large language model can generate text by predicting the next word or sequence of words based on the context of the input text. This is done using a technique called "auto-regression," where the model generates text one word at a time based on the previous words it has generated. 

Large language models have a wide range of applications, including language translation, content creation, chatbots, and more. They have been used to generate news articles, social media posts, and even poetry and fiction.  

Terms to Know 

This glossary covers essential terms and concepts related to large language models, with a focus on providing accessible explanations for those without a technical background. These terms will help you better understand the development, functionality, and potential applications of large language models like GPT. 

1. Large Language Model - A type of AI model that has been trained on vast amounts of text data to understand and generate human language, enabling applications such as translation, summarization, and question-answering. 

2. GPT (Generative Pre-trained Transformer) - A series of large language models developed by OpenAI, known for their ability to generate coherent and contextually relevant text based on a given input. 

3. Transformer - A type of neural network architecture designed for handling sequences of data, particularly in natural language processing tasks. Transformers are known for their self-attention mechanism, which allows them to weigh the importance of different parts of an input sequence. 

4. Pre-training - The initial phase of training a large language model, during which the model learns general language patterns and structures from a vast corpus of text data. 

5. Fine-tuning - The second phase of training a large language model, during which the model is fine-tuned on a smaller, domain-specific dataset to specialize in a particular task or field. 

6. Tokenization - The process of breaking down text into individual words or subwords, called tokens, which are then used as input for a language model. 

7. Vocabulary - The set of unique tokens (words or sub-words) recognized by a large language model, used for both input and output text generation. 

8. Context Window - The maximum number of tokens a language model can consider from the input text when generating a response or prediction. 

9. Zero-Shot Learning - The ability of a pre-trained language model to perform a task without any additional fine-tuning or task-specific training, relying only on its general understanding of language. 

10. Few-Shot Learning - The ability of a pre-trained language model to perform a task with minimal fine-tuning or exposure to task-specific examples. 

11. Transfer Learning - The process of leveraging the knowledge acquired by a model during pre-training on one task to improve performance on a different, but related, task. 

12. Model Size - The number of parameters (weights and biases) in a neural network, often used as a measure of the complexity and capacity of a language model. 

13. Bias - The presence of unfair or unjustified assumptions in a language model's output, often resulting from biases present in the training data. 

14. Overfitting - A situation in which a model becomes too specialized to its training data, leading to poor performance on new or unseen data. 

15. Generalization - The ability of a model to perform well on new, unseen data, by learning the underlying patterns and structures of the training data without memorizing specific examples.
