Microsoft has released its multi-model Copilot harness, which powers various Copilot products and is now available through Microsoft Foundry for developers and enterprise customers.
Key points
- Microsoft Copilot harness is now available through Microsoft Foundry.
- The harness enables multi-model agentic work for developers and enterprises.
- It provides an orchestration layer for AI agents to reason and use tools.
- The system supports open standards and agent plugins for enhanced functionality.
The harness acts as an orchestration layer, providing AI agents with the necessary instructions, context, execution environment, and controls to perform complex work across different AI models.
This offering allows users to build agents that can reason, utilize tools, and complete long-running tasks without needing to switch the harness or their existing technology stack.
Microsoft states that the harness is designed to solve challenges related to performance, quality, and cost in multi-model AI systems, and it is continuously improved to ensure efficiency and low-cost performance.
The GitHub engineering team developed the harness, which supports open standards like MCP and agent skills, as well as agent plugins, enabling users to build on the same technology used in Microsoft and GitHub's own products.
