GPT (Generative Pre-trained Transformer) is a 📝Large Language Model (LLM) architecture that uses deep learning to generate human-like text. Developed by 📝OpenAI, GPT models are pre-trained on massive text datasets and fine-tuned for specific tasks. 📝ChatGPT, OpenAI's conversational 📝Artificial Intelligence (AI) interface, uses GPT architecture to engage in dialogue. In March 2026, OpenAI released GPT-5.4 with native computer-use capabilities, 1M token context window, and agent capabilities for executing complex workflows. GPT technology powers a wide range of generative AI applications across industries.
