In a story that they could have predicted in their own work, a science fiction magazine has asked people to stop sending stories generated by artificial intelligence in the latest sign of apps like ChatGPT gaining prominence.

Clarkesworld, an award-winning sci-fi and fantasy publication based out of New Jersey, has temporarily cut off all submissions because they’ve gotten too many written by AI.

The irony is not lost on the magazine, which has a robot for a mascot.

Publisher and editor-in-chief Neil Clarke cut everyone off on February 20 after he was able to tell that hundreds of stories were not written by humans.

‘By the time we closed on the 20th, around noon, we had received 700 legitimate submissions and 500 machine-written ones,’ Clarke told NPR.
