ChatGPT is, quite simply, the best artificial intelligence chatbot ever released to the general public. It was built by OpenAI, the San Francisco A.I. company that is also responsible for tools like GPT-3 and DALL-E 2, the breakthrough image generator that came out this year. Users have also been finding more serious applications. For example, ChatGPT appears to be good at helping programmers spot and fix errors in their code. It also appears to be ominously good at answering the types of open-ended analytical questions that frequently appear on school assignments. (Many educators have predicted that ChatGPT, and tools like it, will spell the end of homework and take-home exams.)
