Generative Pre-trained Transformers (GPTs) are a family of large language models that use a transformer deep learning architecture. They are pre-trained on vast amounts of text data and then fine-tuned for specific tasks. GPT models can generate human-like text, translate languages, summarize content, analyze data, and write code. These models utilize self-attention mechanisms to process input and predict the most likely output, with a focus on long-range dependencies. GPT models have accelerated generative AI development and are used in various applications, including chatbots and content creation.
