The update is part of Microsoft’s ongoing commitment to bring OpenAI’s latest models to 365 Copilot users within 30 days of their release. Here’s everything you need to know.
With GPT 5, Copilot can now take a request, understand it, and use a real-time router to choose the best AI model for the job. For straightforward queries, it uses a fast, high-throughput model that provides concise responses. For more complex or open-ended questions, Copilot will use GPT 5’s deeper reasoning model that takes extra time to plan, gather relevant context, and check its work before replying.
Microsoft says this “right model for the right job” approach works much like human problem-solving, handling simple tasks quickly while investing more thought and time into challenging ones.
“With GPT-5, Copilot can provide both fast, fluent responses and deep, reasoned analyses. This two-brain approach is what makes the GPT 5 era of Copilot particularly powerful,” Microsoft said.
Licensed Microsoft 365 Copilot users can use GPT 5 for reasoning over both web and work data. A new “Try GPT-5” button will appear in Copilot Chat. Once activated, GPT-5 will power that session. Meanwhile, the rollout for users without a Copilot license will happen in the coming weeks.
