Evolution of Language Models
To truly appreciate the capabilities of generative language models, let’s first look back at their evolution. We’ll explore the traditional rule-based approaches, statistical language models, and how they paved the way for the emergence of powerful generative models.
Traditional Rule-based Approaches
In the early days, language models relied on predefined grammatical rules to generate text. However, these systems were limited in scope and struggled with the complexity of human language.
Statistical Language Models
Statistical language models brought about a significant improvement by analyzing the distribution of words and their probabilities in a given dataset. While they showed promise, they still lacked the ability to grasp the semantic context of language.
The Emergence of Generative Language Models
Enter Generative Pre-trained Transformer (GPT), a revolutionary approach that shook the AI landscape. Developed by OpenAI, GPT leverages the Transformer architecture, offering unparalleled natural language processing capabilities.

How Generative Language Models Work
Before we get into real-world applications, it’s essential to understand the core mechanisms that drive generative language models. In this section, we’ll explain tokenization, self-attention, and the training objectives that contribute to GPT’s success.
Tokenization and Input Representation
Tokenization is the process of breaking down text into smaller units called tokens. GPT uses subword tokenization, enabling it to handle out-of-vocabulary words and improve efficiency.
Self-Attention Mechanism
The self-attention mechanism allows GPT to weigh the importance of each word in a sentence concerning the others, capturing contextual relationships and generating coherent responses.
Training Objective and Loss Functions
During pre-training, GPT uses unsupervised learning with objectives like masked language modeling. We’ll explore these objectives and loss functions that optimize the model’s performance.
