Trains cancelled over fake bridge collapse image

> A BBC journalist ran the image through an AI chatbot which identified key spots that may have been manipulated.

The image is likely AI generated in this case, but this does not seem like the best strategy for finding out if an image is AI generated.

Someone I know is a high school English teacher (being vague because I don’t want to cause them trouble or embarrassment). They told me they were asking ChatGPT to tell them whether their students’ creative writing assignments were AI-generated or not-I pointed out that LLMs such as ChatGPT have poor reliability at this; classifier models trained specifically for this task perform somewhat better, yet also have their limitations. In any event, if the student has access to whatever model the teacher is using to test for AI-generation (or even comparable models), they can always respond adversarially by tinkering with an AI-generated story until it is no longer classified as AI-generated

Reminds me of a Reddit story that made the rounds about a professor asking ChatGPT if it wrote papers, to which it frequently responded afirmatively. He sent an angry email about it, and a student responded by showing a response from ChatGPT claiming it wrote his email.

> student responded by showing a response from ChatGPT claiming it wrote his email

Which is actually fine. Students need to do their own homework. A teacher can delegate writing emails.
