What is sb0s Galaxy?+
sb0s is a new operating system, built from scratch with its own kernel. Galaxy is its first release. Independent of Linux, Windows, and macOS at its foundation, sb0s brings familiar apps and an AI companion into one fresh desktop.
Is sb0s really free?+
Yes. The sb0s operating system and installation image are free. The optional Premium AI experience costs $10 per month. You do not need a cloud subscription to use the OS.
What does Premium AI unlock?+
Our cloud model powers advanced AI and is designed for millisecond-scale task processing. For $10 per month, Edith can use cloud intelligence even on computers that cannot run AI locally. End-to-end speed depends on the request, app, and connection.
How does Edith get things done?+
Edith acts through tools exposed by apps, instead of moving a cursor around the screen. That lets it coordinate multiple tasks in parallel. Speak a request and let your computer get to work. Local AI runs on compatible hardware; Premium AI brings our cloud model to the experience.
Will my apps and laptop work?+
sb0s is built for native Windows, Linux, and Android app support without a virtual machine. Its 100 MB base leaves more room for your work, with apps, files, and local AI models adding storage. Compatibility depends on the app, hardware, and available drivers. The launch film shows Firefox and local voice interaction on an earlier preview build.
When can I get sb0s Galaxy?+
Desktop is coming first, with mobile and cross-device experiences to follow. Watch the launch film for a first look. The free installation image and release date will appear here when they are ready.
