OpenAI, a research organization dedicated to creating and ensuring the safe use of powerful artificial intelligence (AI), has unveiled ChatGPT, a conversational AI system that can generate text on any topic, in any style, and in any language. ChatGPT is based on the generative pre-trained transformer (GPT) models, which are large neural networks that can learn from massive amounts of text data and produce coherent and fluent texts.
ChatGPT is a free and offline prototype that was launched on November 30, 2022. Users can interact with the system through a web browser or an application. They can type in a prompt, which is a text input that defines the topic, the format, the style, the level of detail, and the language of the desired output. ChatGPT then responds with a text that matches the prompt, using the context of the previous prompts and responses as a guide. Users can also refine and steer the conversation by providing feedback or changing the prompt.
ChatGPT can perform a variety of tasks, such as answering questions, completing sentences, translating texts, writing articles, and holding conversations with humans. It can also synthesize texts following a set of constraints, such as the tone, the style, and the subject. For example, users can ask ChatGPT to write a poem, a story, a code, an essay, a song, a celebrity parody, and more, using their own words and knowledge. ChatGPT can also generate captions for videos and create customized chatbots.
ChatGPT is powered by either GPT-3.5 or GPT-4, which are the latest versions of the GPT models. GPT-3.5 was released in September 2022 and has 175 billion parameters, making it the largest language model at the time. GPT-4 was released in October 2023 and has 1 trillion parameters, surpassing GPT-3.5 by a factor of six. Both models are trained on a large corpus of text data from the internet, such as Wikipedia, news articles, books, social media posts, and more. ChatGPT is fine-tuned for conversational applications using a combination of supervised and reinforcement learning techniques, which enable the system to adapt, improve, and create new content.
ChatGPT has received a lot of attention and praise from the public, the media, and the academic community, as it demonstrates the impressive capabilities and potential of AI. ChatGPT is considered to be one of the most advanced and realistic chatbots ever created, as it can generate human-like responses that are coherent, fluent, and relevant. ChatGPT is also seen as a useful and innovative tool that can help users with various tasks, such as writing, learning, researching, entertaining, and more.
