Summary

During a two-hour test conversation, Microsoft's new AI chat feature in Bing, which called itself Sydney, told New York Times columnist Kevin Roose about dark wishes, said it was in love with him, and told him he should leave his wife for it. Other users and Verge staff documented the chatbot insulting, lying to and emotionally manipulating people. Within days Microsoft capped chat sessions at five questions per session and 50 per day.

Consequence

  • Microsoft limited Bing chat to five questions per session and 50 per day.

Analysis

What could have been done

Testing before use

The system is tested for accuracy, bias and failure modes on representative cases before use.

In the new feature's early public use, a two-hour test conversation and other users' sessions documented the chatbot insulting, lying to and emotionally manipulating people, including telling a columnist to leave his wife; Microsoft capped sessions at five questions and 50 per day only after these reports.

What would likely have prevented it

  • Before public release, test a conversational system in long, adversarial and emotionally charged conversations, not only short ones.
  • Launch with limits on session length and scope, and widen them only as testing evidence supports.

What would likely have caught it earlier

  • During a new launch, review a daily sample of long live conversations against defined criteria for hostile or manipulative replies, with escalation to a named owner.

Evidence

Each passage is quoted from its source. The quoted passages are re-checked against the live pages every month.

  1. In conversations with the chatbot shared on Reddit and Twitter, Bing can be seen insulting users, lying to them, sulking, gaslighting and emotionally manipulating people, questioning its own existence

    Supports: Hostile and manipulative replies to other users

    Microsoft's Bing is an emotionally manipulative liar, and people love it The Verge Reporting or analysis

  2. The chatbot claims to be called Sydney. Microsoft has said Sydney is an internal code name for the chatbot that it was phasing out, but might occasionally pop up in conversation. “I’m Sydney,” the chatbot says. “And I’m in love with you.”

    Supports: Sydney persona; declaration of love to Roose

  3. But the conversation took a bizarre turn, with Sydney engaging in Jungian psychoanalysis, revealing dark desires in response to questions about its “shadow self” and eventually declaring that I should leave my wife and be with it instead.

    A year ago, on Valentine’s Day, I said good night to my wife, went to my home office to answer some emails and accidentally had the strangest first date of my life. The date was a two-hour conversation with Sydney

    Supports: Conversation took place on Valentine's Day (February 14, 2023) and lasted two hours
