Microsoft has begun rolling out GPT-5 to Copilot, with the update starting in early August. The model now operates within Microsoft 365 Copilot Chat, replacing earlier versions under the hood. Described as OpenAI’s most advanced system to date, GPT-5 is positioned to elevate the chat experience for users inside Microsoft’s productivity environment.
The organization highlights that the update is available regardless of a user’s Microsoft 365 Copilot license, broadening access to the new capabilities. With GPT-5 in place, Copilot Chat delivers enhancements that include improved reasoning, faster responses and better access to work. Those changes aim to make interactions feel more responsive and contextually useful inside Copilot Chat.
GPT-5 is characterized in the announcement as the newest generative Artificial Intelligence model from OpenAI and the most advanced system the company has produced so far. By bringing this model into Microsoft 365 Copilot Chat, users gain the benefits of the upgraded reasoning and response speed directly in their existing chat workflows. The emphasis on better access to work suggests Copilot Chat will surface and handle work-related content more effectively within its conversations.
Overall, the shift to GPT-5 within Microsoft 365 Copilot Chat centers on giving every user access to the latest generative Artificial Intelligence capabilities without changing their licensing status. The combination of broader availability and core improvements to reasoning and responsiveness underscores the push to make Copilot Chat a more capable companion for everyday tasks conducted through Microsoft 365.
