O penAI officially launched its new GPT-5 models today, and Microsoft is now bringing GPT-5 to Copilot, Microsoft 365 Copilot, Azure AI Foundry, GitHub Copilot, and more. It’s part of a big simultaneous release of GPT-5 that will show up in Copilot as the new smart mode that I detailed in Notepad last month.

The new GPT-5 Smart mode, which OpenAI describes as the 'best model to date', is automatically rolling out for free to Copilot users.

GPT-5 is here, and Microsoft is integrating it into everything from chatbots to developer tools. Here's what's new, what works, and what to expect.
