意味

OpenAI's AI chatbot; the tool that introduced millions of Japanese people to generative AI in 2023, often shortened to GPT or チャGPT.

ChatGPT became a cultural phenomenon in Japan in 2023, with its usage spreading from tech enthusiasts to students, office workers, and creators almost overnight. Japanese users frequently shorten it to GPT (ジーピーティー) or affectionately write it as チャGPT. Discussions range from practical uses like writing emails and summarising documents to concerns about academic cheating and job replacement. The term is now part of everyday Japanese tech conversation.
