In this edition of our monthly roundup, we’re recapping new features released in Microsoft Copilot Studio in October 2025.

Today, we are making GPT-5.1 available in Microsoft Copilot Studio, alongside OpenAI’s release. This is available as an experimental model for U.S. customers in early release cycle Power Platform environments. The GPT-5.1 series brings improved adaptability in thinking time in both chat and reasoning.

Today, we’re bringing AI-powered building to employees across the organization, with new agents for Microsoft 365 Copilot customers in the Frontier program: App Builder and Workflows. Using these agents and Copilot Studio, Copilot now enables employees to turn ideas into impact by creating apps, workflows, and agents.

We are excited to share that agent publishing from Microsoft Copilot Studio to Microsoft 365 Copilot is now generally available.

MCP now includes a new set of features and enhancements that support more robust and scalable deployments: tool listing, enhanced tracing, and more.

Copilot Studio is excited to introduce two major updates: agent evaluation and enhanced analytics, both designed to support makers across the agent lifecycle.

The new unified authoring canvas in Power Virtual Agents has only been in preview for a few weeks but it has already received a ton of positive community reviews and coverage. This article is a summary of these and a grateful testimony to the Power Platform community members who created these amazing contents.

We are excited to announce the Public Preview launch of Power Virtual Agents’ new and enhanced authoring canvas!.
