What's new in Microsoft Copilot | October 2025

GPT-5 will soon be established as the default model in Copilot Chat. The real-time router in GPT-5 enables Copilot to automatically select the most appropriate model for each prompt, using a high-throughput chat model for faster replies and a reasoning model for complex, multi-step queries.

A toggle option will temporarily allow switching between models when the reasoning model is selected. This toggle will be enabled by default and later removed as part of the rollout.

Rollout timeline:

• General Availability: Beginning November 2025 for Microsoft 365 Copilot users
• Subsequent rollout: Extended later to users without a Microsoft 365 Copilot license

Impact:

• Who is affected: Copilot Chat users across Microsoft 365 environments
• What will happen: GPT-5 will replace previous versions as the default model, enhancing response efficiency and reasoning depth.
