OpenAI designates GPT‑5.6 as preferred model for Microsoft Copilot 365

OpenAI has announced a new family of language models that will continue to underpin Microsoft’s suite of workplace and productivity applications. The updated models, which include the latest iterations of the GPT series, are designed to deliver more reliable, context‑aware responses and tighter integration with Microsoft’s cloud services.

Microsoft will embed these models across its flagship productivity tools, such as Word, Outlook, Teams, and Power Point, enhancing features like smart drafting, real‑time translation, and advanced data analysis. The partnership also extends to the Microsoft Graph API, enabling developers to build custom applications that leverage the models’ capabilities for workflow automation and knowledge management.

By extending OpenAI’s technology into Microsoft’s enterprise ecosystem, the collaboration aims to streamline daily work tasks and improve productivity for businesses worldwide. The rollout is expected to roll out in phases over the coming months, with ongoing updates to refine performance and security.
