Microsoft 365 Copilot will replace GPT-4o with OpenAI’s GPT-Image-1.5 from mid-December 2025 to late January 2026, enhancing image generation quality, speed, and accuracy without changing admin controls or compliance settings. Eligible users receive the update automatically.
We’re updating Microsoft 365 Copilot image generation experiences by introducing OpenAI’s latest image generation model—GPT‑Image‑1.5—into Microsoft 365 Copilot and Copilot Chat. This update improves prompt adherence, image editing precision, visual fidelity, and generation speed, enabling users to create higher-quality, more accurate visuals across Copilot Chat entry points and the Create experience in the Microsoft 365 Copilot app.
