About Lucebox

Lucebox makes workstations for local AI inference. They're private, always-on machines that arrive with Lucebox's inference engine installed and tuned, so developers point Claude Code, Codex or OpenCode on their own hardware. Lucebox is building toward a new category of self-improving personal AI computers that learn from the work you do every day, training small models on your own context until they're faster and better than the cloud at your tasks. The engine is open source, with 2.9K stars on GitHub and 95K+ downloads on Hugging Face.
