A GPT-3-powered bot has been caught posing as a human on Reddit after more than a week of rampant posting on one of the site's most popular subreddits. Under the username of thegentlemetre, the bot had been churning out a post per minute on /r/AskReddit, a sub with more than 30 million users. That behavior raised the suspicions of writer Philip Winston. "I read through some of the posts and they reminded me of text I'd seen from OpenAI's language model GPT-3," Winston wrote on his blog. Winston shared his theory on the subreddit /r/GPT3. Another Redditor named Wiskkey noticed that the structure of its writing was similar to that used by the Philosopher AI, a controversial text generator powered by GPT-3.

Busted: A bot powered by OpenAI's powerful GPT-3 language model has been unmasked after a week of posting comments on Reddit. Under the username /u/thegentlemetre, the bot was interacting with people on /r/AskReddit, a popular forum for general chat with 30 million users. It was posting in bursts of roughly once a minute. Fooled ya--again: It's not the first time GPT-3 has fooled people into thinking what it writes comes from a human. In August a college student published a blog post that hit the top spot on Hacker News and led a handful of people to subscribe.
