What is GPT?
TL;DR
OpenAI's series of large language models. The foundational technology behind ChatGPT, which brought AI to the mainstream.
GPT: Definition & Explanation
GPT (Generative Pre-trained Transformer) is a series of large language models developed by OpenAI. The name reflects three key characteristics: 'Generative' (generates text), 'Pre-trained' (trained on large datasets before deployment), and 'Transformer' (built on the Transformer architecture). The series began with GPT-1 in 2018 and has evolved through GPT-2, GPT-3, GPT-3.5, GPT-4, and GPT-4o. The release of ChatGPT in November 2022 — built on GPT-3.5 — brought AI technology into mainstream public awareness. GPT-4 introduced multimodal capabilities, enabling the model to understand images as well as text. Through the OpenAI API, developers can integrate GPT's capabilities into their own applications, making it the backbone of countless AI-powered services.
