Microsoft has upgraded all its Copilot tools with OpenAI's latest GPT-5 model, now available through a new Smart Mode.

The update brings enhanced speed and better performance across Microsoft 365 Copilot, Azure AI Foundry, GitHub Copilot, and the Windows AI chatbot pre-installed on PCs.

Users can try the Smart Mode via the Copilot website, which can be selected from a model selector below the text input. Notably, a Microsoft account is not required to use this new mode.

The Smart Mode rollout is gradual, and while not yet visible in the Windows Copilot app for everyone, early users have reported that GPT-5 delivers faster and more accurate responses compared to earlier models.

Unlike the free ChatGPT tier that limits queries and switches automatically to older versions after usage caps, Copilot offers fewer restrictions, allowing more extensive use.

Microsoft's AI Red Team tested GPT-5 thoroughly before release, highlighting its strong safety profile and improved reasoning capabilities.

Microsoft 365 Copilot benefits from GPT-5's advanced abilities to answer complex questions, maintain coherence over long conversations, assist with email replies, and analyse documents effectively.

GitHub Copilot has also been enhanced with GPT-5, significantly improving reasoning, code quality, and overall user experience. The upgrade positions Microsoft's AI tools to support developers and professionals across multiple platforms better.
