From open source to agentic systems: Microsoft at Open Source Summit North America 2026
Open source is the foundation for AI and, as AI workloads scale, developers need that foundation to be more secure, more predictable, and easier to build apps and agents.
Conductor: Deterministic orchestration for multi-agent AI workflows
Conductor is an open-source CLI (MIT license, Microsoft org) that takes a different approach: you define your multi-agent workflows in YAML, and the routing between agents is deterministic. Jinja2 templates and expression evaluation handle conditions and branching. The orchestration layer consumes zero tokens. The structure is fixed at definition time—and that's the point.
PostgreSQL enters its AI era: Run PostgreSQL like a pro in the era of AI and rapid growth
Postgres can handle intelligent workloads and scale without sacrificing security, performance, reliability, or operational ease.
Continuing the story of early DOS development
In 2018 we (re)-open-sourced MS‑DOS 1.25 and 2.11, and more recently in 2024 we were able to make the source for MS‑DOS 4.0 available to the public as well. Today, on 86-DOS 1.00’s 45th anniversary, we’re continuing that tradition with the earliest DOS source code discovered to date.
How Drasi used GitHub Copilot to find documentation bugs
