  --header 'Content-Type: application/json' \
  --data '{
    "input_text": "Clearly, artificial intelligence is having a moment. Back in November of 2022, San Francisco–based OpenAI debuted ChatGPT, a large language model chatbot that can mimic human writing styles, from a simple Siri-level response to a novel short story in the style of Shakespeare. The reaction was voracious. \"The College Essay Is Dead,\" proclaimed one headline from The Atlantic of ChatGPT'''s potential to assist shortcut-seeking students. Seattle Public Schools banned it from learning devices, and the University of Washington released guidance for professors unsure how to navigate the plagiarism minefield. Not even three months later, after a rumored $10 billion investment in OpenAI, Microsoft unveiled \"new Bing\"—part search engine, part AI butler—during a Redmond press event."
