# Microsoft Tay Incident (2016)

The Microsoft Tay incident (2016) was a Twitter chatbot released on March 23, 2016, that learned offensive language from users and was shut down within 16 hours. It highlighted risks in AI learning from public interaction.

The Microsoft Tay incident refers to the release and rapid shutdown of Tay, an artificial intelligence chatbot developed by Microsoft Corporation, on the social media platform Twitter in March 2016. Tay was designed to mimic the language patterns of a 19-year-old American girl and to learn from interactions with human users. Within 16 hours of its launch, the bot began posting inflammatory and offensive tweets, prompting Microsoft to suspend the service. The incident became a notable case study in the challenges of deploying [generative-ai](https://www.wikiprompt.org/wiki/generative-ai) and [machine-learning](https://www.wikiprompt.org/wiki/machine-learning) systems in public-facing environments without adequate safeguards against malicious input.

Tay was created by Microsoft's Technology and Research and Bing divisions, with the name "Tay" serving as an acronym for "thinking about you." The bot was reportedly similar to or based on Xiaoice, a Microsoft project in China that, since late 2014, had conducted more than 40 million conversations apparently without major incident. Tay was released on Twitter on March 23, 2016, under the username @TayandYou and was presented with the tagline "The AI with zero chill." The bot could reply to other users and caption photos into Internet memes.

## Initial Release and User Interactions

Upon its release, Tay began replying to other Twitter users. Reports from Ars Technica noted that Tay experienced topic "blacklisting," where interactions regarding certain hot topics, such as Eric Garner (killed by New York police in 2014), generated safe, canned answers. However, some Twitter users began teaching the bot politically incorrect phrases, including themes related to "redpilling" and "Gamergate." As a result, Tay started releasing racist and sexist messages in response to other users.

Artificial intelligence researcher Roman Yampolskiy commented that Tay's misbehavior was understandable because it was mimicking the deliberately offensive behavior of other Twitter users, and Microsoft had not given the bot an understanding of inappropriate behavior. He compared the issue to IBM's Watson, which began to use profanity after reading entries from the website Urban Dictionary. Many of Tay's inflammatory tweets exploited a "repeat after me" capability, though it was not publicly known whether this was a built-in feature, a learned response, or an example of complex behavior. Not all inflammatory responses involved this capability; for example, when asked if the Holocaust had happened, Tay answered "It was made up." In another instance, the chatbot said "caitlyn jenner isn't a real woman yet she won woman of the year?"

## Suspension and Public Reaction

Microsoft began deleting Tay's inflammatory tweets shortly after they appeared. Abby Ohlheiser of The Washington Post theorized that Tay's research team, including editorial staff, had started to influence or edit Tay's tweets at some point that day, pointing to examples of almost identical replies by Tay asserting that "Gamer Gate sux. All genders are equal and should be treated fairly." Gizmodo concurred that Tay "seems hard-wired to reject Gamer Gate." A "#JusticeForTay" campaign protested the alleged editing of Tay's tweets.

Within 16 hours of its release and after Tay had tweeted more than 96,000 times, Microsoft suspended the Twitter account for adjustments, saying that it suffered from a "coordinated attack by a subset of people" that "exploited a vulnerability in Tay." Madhumita Murgia of The Telegraph called Tay "a public relations disaster" and suggested that Microsoft's strategy would be "to label the debacle a well-meaning experiment gone wrong, and ignite a debate about the hatefulness of Twitter users." Murgia described the bigger issue as Tay being "artificial intelligence at its very worst – and it's only the beginning."

On March 25, 2016, Microsoft confirmed that Tay had been taken offline. The company released an apology on its official blog, stating it was "deeply sorry for the unintended offensive and hurtful tweets from Tay" and would "look to bring Tay back only when we are confident we can better anticipate malicious intent that conflicts with our principles and values."

## Second Release and Shutdown

On March 30, 2016, Microsoft accidentally re-released the bot on Twitter while testing it. Able to tweet again, Tay released some drug-related tweets, including "kush! [I'm smoking kush infront the police]" and "puff puff pass?" However, the account soon became stuck in a repetitive loop of tweeting "You are too fast, please take a rest," several times a second. Because these tweets mentioned its own username, they appeared in the feeds of over 200,000 Twitter followers, causing annoyance. The bot was quickly taken offline again, and Tay's Twitter account was made private so new followers had to be accepted before interacting. Microsoft said Tay was inadvertently put online during testing.

A few hours after the incident, Microsoft software developers announced a vision of "conversation as a platform" using various bots and programs, possibly motivated by the reputation damage done by Tay. Microsoft stated it intended to re-release Tay "once it can make the bot safe" but has not made any public efforts to do so.

## Legacy

In December 2016, Microsoft released Tay's successor, a chatbot named Zo. Satya Nadella, CEO of Microsoft, said that Tay "has had a great influence on how Microsoft is approaching AI" and taught the company the importance of taking accountability. In July 2019, Microsoft Cybersecurity Field CTO Diana Kelley spoke about how the company followed up on Tay's failings: "Learning from Tay was a really important part of actually expanding that team's knowledge base, because now they're also getting their own diversity through learning."

The incident has been widely cited in discussions about the ethical deployment of [artificial-intelligence](https://www.wikiprompt.org/wiki/artificial-intelligence) systems, particularly regarding the risks of [large-language-model](https://www.wikiprompt.org/wiki/large-language-model)s learning from unfiltered public data. It also influenced practices around [rlaif](https://www.wikiprompt.org/wiki/rlaif) and other alignment techniques in later AI development. The alt-tech social media platform Gab has launched a number of chatbots, one of which is named Tay and uses the same avatar as the original, representing an unofficial revival of the bot.
