Xbox Manager Says Company Uses AI After Posting Rapid 'Vibe‑Coded' Prototype

The public thread raises questions about transparency, developer practices, reputational risk for Xbox.

Overview

  • Brandon Stirrup, a senior Xbox business strategy manager, posted a thread Monday saying he ‘vibe coded’ a rudimentary game in about three hours and that Xbox uses AI, then deactivated his X account within 24 hours due to the volume of replies.
  • Stirrup argued developers who refuse to adopt AI risk obsolescence and claimed “hundreds at Xbox” use AI, a figure that multiple outlets reported could not be independently verified and that Xbox has not publicly quantified.
  • The posts followed Microsoft’s recent launch of Xbox Labs, the company initiative to experiment with emerging tech including AI, which Microsoft presents as a cautious, exploratory effort to test tooling and prototypes.
  • Coverage noted persistent negative player reaction to low‑quality AI outputs—often called ‘Gen‑AI slop’—and said that visible use of generative tools raises disclosure and trust challenges that can damage a studio’s reputation.
  • Stirrup’s willingness to accept consequences and his account deactivation underscore internal sensitivity about public comments on AI and make clearer oversight of disclosure and internal policies at Xbox a likely next step.
