OpenAI's AI Tools Now Work on Amazon's Cloud, Not Just Microsoft's

OpenAI's AI models are now available on Amazon's cloud computing service, ending what was effectively Microsoft's exclusive hold on OpenAI distribution. Starting June 2026, companies can use OpenAI's technology directly within Amazon's environment. The shift followed an eight-month series of deals: a $38 billion partnership in November 2025, and negotiations through spring that loosened Microsoft's original control.
