ChatGPT (English)

Where does "ChatGPT" come from?

ChatGPT is a modern compound word formed by combining 'chat,' a clipping of the verb 'chatter,' with the acronym 'GPT.' While GPT is technically an initialism for a specific data storage format, in this context it stands for 'generative pre-trained transformer,' describing the core artificial intelligence technology behind the bot. The term first appeared in 2022 to name the now-ubiquitous AI assistant.
