Chat GPT (Generative Pre-trained Transformer) is an advanced artificial intelligence (AI) model created by OpenAI. It belongs to the family of large language models (LLMs) and is designed to understand and generate human-like text. Chat GPT’s primary function is to engage in conversations, answer questions, and create various forms of written content. To fully grasp how Chat GPT learns, it is essential to understand its underlying architecture and training process.

• Architecture: Chat GPT is based on the Transformer architecture, which uses self-attention mechanisms to weigh the importance of different parts of the input data. This allows the model to understand context and relationships between words in a sentence more effectively.
• Pre-training: The model is pre-trained on a massive dataset of text from the internet, including books, articles, and websites. During this phase, Chat GPT learns the structure and patterns of language by predicting the next word in a sequence.
• Fine-tuning: After pre-training, Chat GPT is fine-tuned on a smaller dataset of conversational text. This process optimizes the model for dialogue-based interactions, enabling it to provide coherent and contextually relevant responses.

Understanding Chat GPT involves recognizing its capacity for language generation and the architectural and training foundations that enable it to perform tasks effectively. These factors play a crucial role in how the model learns and adapts to new information.
