A Large Language Model (LLM) is a type of artificial intelligence model designed to understand, generate, and manipulate human language. LLMs are built using deep learning techniques, specifically a type of neural network architecture called the Transformer. They are trained on vast amounts of text data from diverse sources such as books, articles, and websites to learn the patterns, structures, and nuances of language.
The “large” in Large Language Model refers to the scale of the model, both in terms of the number of parameters and the size of the training data. A model with more parameters can learn and represent more complex relationships in the data, which often leads to better performance. However, it also requires more computational resources to train and use.
Large Language Models have shown impressive capabilities in various natural language processing (NLP) tasks, such as machine translation, summarization, sentiment analysis, question-answering, and conversational AI. Some well-known examples of LLMs include OpenAI’s GPT series (GPT-3 being one of the most popular), Google’s BERT, and Facebook’s RoBERTa. These models have greatly advanced the state of the art in NLP and enabled the development of numerous applications across domains like search engines, chatbots, and content generation tools.
