Fast source checkSource check: OpenAI announced July 9, 2026 that GPT-5.6 will become the preferred model in Microsoft 365 Copilot for Word, Excel, PowerPoint, Chat, and Cowork.

Why preferred model status matters

Preferred status means default capability inside Word, Excel, PowerPoint, Chat, and Cowork for Microsoft 365 customers. OpenAI and Microsoft frame GPT-5.6 as stronger useful work per token for drafting, analysis, presentations, and cross-functional collaboration.

Training, policy, and quality review become more important than model shopping. If Copilot gets sharper by default, bad prompts and weak review processes will scale faster too. Document ownership, citation habits, and approval rules before power users improvise them.

Alberta SME takeaway

Many local firms already pay for Microsoft 365. The practical path is often Copilot governance plus private AI for sensitive work — not a sudden full-stack rebuild. Measure one workflow: proposals, invoices, or weekly reporting.

Opcelerate recommendationOpcelerate recommends a Copilot Default Pilot: one department, three recurring tasks, quality scorecards, and a private-AI overflow lane for confidential data.
