What is ChatGPT? The BBC Science Focus describes ChatGPT as a "language processing AI model. This simply means it is a program able to understand human language as it is spoken and written, allowing to understand the worded information it is fed, and what to spit back out."
What are ChatGPT's limitations? It can understand spoken or written language, but it can’t produce video, sound, or images. Additionally, since it relies on its input to generate responses, ChatGPT can have trouble with more recent (1 year or less) events, issues, or topics. (Source: BBC Science Focus)
