What Is GPT (Generative Pre-trained Transformer)?
GPT (Generative Pre-trained Transformer) is a family of large language models developed by OpenAI that use the transformer architecture to generate coherent, human-like text based on input prompts.
How GPT (Generative Pre-trained Transformer) Works
GPT models are 'generative' because they produce new text, 'pre-trained' because they learn from massive internet text data before being fine-tuned for specific tasks, and based on the 'transformer' neural network architecture. Starting with GPT-1 in 2018, each generation has grown significantly larger and more capable. GPT-4 and its variants (GPT-4o, GPT-4o mini) power ChatGPT, one of the most widely used AI applications in the world. The GPT series popularized the concept of general-purpose AI assistants and demonstrated that scaling model size and training data leads to emergent capabilities like reasoning and code generation.
