ChatGPT is an artificial-intelligence chatbot developed by San Francisco-based AI research company Open AI. Released in November 2022, it can have conversations on topics from history to philosophy, generate lyrics in the style of Taylor Swif. or Billy Joel, and suggest edits for computer programming code.
ChatGPT is trained on a vast compilation of articles, websites and social-media posts collected from the Internet as well as real-time conversations—primarily in English—with humans hired by Open AI. It learns to mimic(模仿) the grammar and structure of the writing and reflects frequently-used phrases.
The chatbot isn't always accurate: its sources aren't fact-checked and it relies on human feedback to improve its accuracy.
Open AI developed ChatGPT as part of a strategy to build AI software that will help the company turn a profit. In January, Microsoft unveiled a fresh multibillion-dollar investment in Open AI and said it planned to add ChatGPT into its Bing search app and other products. Competitors Google and Baidu are pushing to launch similar tools.
ChatGPT is free. Open AI released the chatbot as a research preview and users can try it through a particular website. In February, Open AI also launched a high-level version for $20 a month, starting in the US, that will give subscribers priority access.
Media companies including Buzz Feed and the publisher of Sports Illustrated have announced plans to generate content such as quizzes and articles with Chat GPT. Some schools have blocked access to the service on their networks to reduce cheating, while others are actively encouraging students to use the tools ethically(道德上).
AI chat bots and other generative AI programs are mirrors to the data they consume. They repeat and remix what they are fed to both great effect and great failure. Transformer-based AI program failures are particularly difficult to predict and control because the programs rely on such vast quantities of data that it is almost impossible for the developers to grasp what that data contains.
ChatGPT, for example, will sometimes answer questions correctly on topics where it gained high-quality sources and frequently talked with its human trainers. It will respond nonsense to topics that contain a lot of misinformation on the Internet such as conspiracy theories.
Some artists have also said that AI image generators copy their artwork and threaten their livelihoods, while software engineers have said that code generators rip large amounts of their code.
