At Red Hat Summit 2026, the company announced Fedora Hummingbird will be delivered as an OCI image that is a standardized, lightweight, and portable package containing everything needed to run a Linux application – code, runtime, system tools, and settings.

Fedora Hummingbird will run within a container, include no package manager, and have no shell. This means it will contain the application and its runtime dependencies. This new OS will run in containers, virtual machines, and on bare metal. With the help of Syft and Grype, vulnerability scans will run continuously; when an upstream fix is made available, it will be patched, rebuilt, tested, and published.

Hummingbird will also be both atomic and immutable, to add even more security.

But what is the true purpose of Fedora Hummingbird? According to Red Hat, it's all about agentic AI – or, rather, agent-first builders.

Gunnar Hellekson, vice president and general manager for Red Hat Enterprise Linux, said of the need for Hummingbird, "The Linux market has split: IT operations teams need the decades-long stability of Red Hat Enterprise Linux, while builders, both human and agentic, demand upstream velocity and image-based workflows." Hellekson continues, "Fedora Hummingbird Linux will define the platform for the agents that build the future of enterprise software."

Fedora Hummingbird will be free and offer frictionless onboarding for AI agents, upstream velocity for rapid innovation, an agent-enhanced software pipeline, support through a Red Hat subscription, and extended offerings for compliance, scale, and production workloads.
