Large Language Models, such as GPT (Generative Pre-trained Transformer), are advanced AI models designed for natural language processing. They are trained on vast amounts of text data to learn language patterns, context, and relationships. GPT, specifically, refers to a popular large language model developed by OpenAI. It utilizes the Transformer architecture and excels in generating coherent text. These models can be fine-tuned for specific tasks and domains. GPT models have a wide range of applications, including text generation, summarization, sentiment analysis, and chatbot development. They demonstrate impressive language understanding capabilities, making them valuable tools for processing human-like text.
