Understanding GPT models

GPT, which stands for Generative Pre-trained Transformer, is an artificial intelligence model known as a transformer model. It's called "pre-trained" because it's trained on a large body of text data before it's fine-tuned for specific tasks. This equips it with grammar, factual knowledge, and reasoning abilities. When you ask GPT for something, it thinks about the words that should come next based on what it knows. It does this one word at a time, using what it just said to help with the next word.

Different GPT models exist because they are created at different times with improvements in technology and training methods, leading to better performance and capabilities. The latest model is GPT-5, the most advanced and powerful version developed by OpenAI.^[1]

Today, there are several content creation tools that operate using GPT technology, such as ChatGPT, Copy AI, Writesonic, and Jasper, among many others. Some products, like Notion, have incorporated GPT to enable AI writing as part of their offerings.
