OpenAI 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 smart mode in Copilot allows the AI assistant to switch models for you to use deeper reasoning or quickly respond based on the task. Much like how OpenAI is making GPT-5 available to free users of ChatGPT, Copilot will also have free access to GPT-5.

Microsoft 365 Copilot users will also get access to GPT-5 today. “With GPT-5, Microsoft 365 Copilot is better at reasoning through complex questions, staying on track in longer conversations and understanding the user’s context,” explains Microsoft in a blog post. Copilot Studio will also get access to GPT-5 as part of today’s releases.

GitHub is also bringing GPT-5 to all paid GitHub Copilot plans today, allowing developers to try out the code writing improvements to OpenAI’s latest model. OpenAI’s new GPT-5 model comes in four different versions, and has big improvements in reasoning and code quality. GPT-5 is designed for logic and multi-step tasks, while GPT-5-chat is tuned for enterprise applications with multimodal context-aware conversations.

Finally, Microsoft is also making GPT-5 available through Azure AI Foundry, so developers can utilize it in AI-powered apps. Developers will be able to use the model router in Azure AI Foundry “to ensure the right model is used” for the task or query.
