What stands the letter GPT in ChatGPT for?

The letters «GPT» in ChatGPT stand for «Generative Pre-trained Transformer.» This refers to the type of language model used to create the ChatGPT AI, which is a specific implementation of the Transformer architecture developed by OpenAI. The «Generative» part of the name indicates that the model can generate text independently rather than just recognizing patterns or responding to prompts. The «Pre-trained» part means that the model was trained on a large amount of text data before being fine-tuned for its specific application, in this case, generating human-like responses to user queries.
