AI Trained on 4Chan Becomes ‘Hate Speech Machine

AI researcher and YouTuber Yannic Kilcher trained an AI using 3.3 million threads from 4chan’s infamously toxic Politically Incorrect /pol/ board. He then unleashed the bot back onto 4chan with predictable results—the AI was just as vile as the posts it was trained on, spouting racial slurs and engaging with antisemitic threads. After Kilcher posted his video and a copy of the program to Hugging Face, a kind of GitHub for AI, ethicists and researchers in the AI field expressed concern.

The bot, which Kilcher called GPT-4chan, “the most horrible model on the internet”—a reference to GPT-3, a language model developed by Open AI that uses deep learning to produce text—was shockingly effective and replicated the tone and feel of 4chan posts. “The model was good in a terrible sense,” Klicher said in a video about the project. “It perfectly encapsulated the mix of offensiveness, nihilism, trolling, and deep distrust of any information whatsoever that permeates most posts on /pol.”

According to Kilcher’s video, he activated nine instances of the bot and allowed them to post for 24 hours on /pol/. In that time, the bots posted around 15,000 times. This was “more than 10 percent of all posts made on the politically incorrect board that day,” Kilcher said in his video about the project.
