Sam Altman Blasts Slack, Teases 'AI Cloud' as Elon Musk Predicts OpenAIMicrosoft Showdown

The remarks refocus attention on OpenAI's uneasy ties with Microsoft, a major investor that now lists the startup as a competitor.

Overview

  • In a viral interview, Sam Altman said Slack creates “a lot of fake work” and predicted AI agents could supplant tools like Google Docs, email, and Slides.
  • Altman separately posted that OpenAI is exploring ways to sell compute capacity, signaling a potential “AI cloud” offering rather than a launched product.
  • Elon Musk responded on X that OpenAI will compete directly with Microsoft and called continued Microsoft support for OpenAI “insanely suicidal.”
  • Microsoft has invested about $11.6 billion in OpenAI and holds a stake valued around $135 billion, even as the company develops its own models for Copilot.
  • The partnership increasingly overlaps with competition, as Microsoft has named OpenAI a rival and OpenAI executives have warned of cloud providers learning from its advances.
