Microsoft Build 2025 delivered a wave of updates for agent makers. I’ve pulled together the announcements across Copilot Studio and Power Platform that stood out most to me- especially those that will shape how we build intelligent, responsive, and business-aware agents.
Copilot Tuning in Copilot Studio
Copilot Tuning is a leap forward for customisation. It allows organisations to fine-tune Microsoft 365 Copilot using their own data, workflows, and tone—without writing code. This means you can build domain-specific agents that reflect your business’s language, structure, and expertise.
For example, a legal firm could create an agent that drafts documents in their preferred format, using past work as a guide. This kind of tuning makes Copilot more than just a helpful assistant—it becomes a true extension of your team, grounded in your unique context.
Agent Feed and Agent Flows in Power Apps
The new Agent Feed in Power Apps introduces a dynamic way to interact with your agents. It functions like a social feed, surfacing updates, suggestions, and insights in a format that’s easy to scan and act on. This makes it easier to stay on top of what your agents are doing and how they’re evolving.
Furthermore, Agent flows bring deeper integration between Power Apps and Power Automate. You can now trigger flows directly from within Power Apps with easy-to-configure actions, like sending alerts or initiating approvals.
Multi-Agent Support
Multi-agent support in Copilot Studio means that you can design and deploy multiple agents that can work together, each with its own role, responsibilities, and knowledge base to solve more complex, multi-step business problems. For example:
- One agent might handle data intake—gathering information from users or systems.
- Another could be responsible for summarising or transforming that data.
- A third might manage approvals or escalations, interacting with human stakeholders.
Each agent can be tuned to a specific domain or task, and they can pass context and outputs between one another. This modular approach mirrors how teams work in real life and it makes your AI solutions more maintainable, scalable, and adaptable.
