GPT, or Generative Pre-trained Transformer, is an advanced language model developed by OpenAI. It uses deep learning techniques to understand and generate human-like text based on the input it receives. By analyzing vast amounts of text data, GPT can produce coherent and contextually relevant responses, making it useful for various applications, including chatbots, content creation, and language translation. The model operates by predicting the next word in a sentence, allowing it to generate complete thoughts and ideas. Its versatility and ability to learn from diverse sources enable it to assist users in numerous tasks, enhancing communication and information accessibility.
