open-infra-index is a central “infrastructure index” repository maintained by DeepSeek AI that acts as a catalog and hub for a collection of production-tested AI infrastructure tools and internal building blocks they have open-sourced. Instead of a single monolithic codebase, it functions more like an index or launching point: linking and documenting a set of library repos (e.g. FlashMLA, DeepEP, DeepGEMM, 3FS, etc.) that together form DeepSeek’s infrastructure stack. The repo's README describes the project as sharing “humble building blocks” of their online service—code that is documented, deployed, and battle-tested in production. The timing of its opening matches DeepSeek’s “Open-Source Week” campaign (starting around February 2025) when they gradually released internal infrastructure components publicly. It is licensed under CC0-1.0 (Creative Commons Zero) to maximize openness.
Features
- Catalog of open infrastructure repos — acts as a central hub pointing to multiple internal tools (FlashMLA, DeepEP, DeepGEMM, 3FS, etc.)
- Production-vetted building blocks — each subproject is claimed to be used in DeepSeek’s live systems, not just experimental code
- Roadmaps and open development announcements — the index publishes DeepSeek’s plans, e.g. open-sourcing their inference engine
- Permissive license (CC0-1.0) — maximally opens the content for reuse and modification
- Transparency narrative & context — includes “Open-Source Week” context, mission statements, and rationale for sharing
- Community interface and engagement — discussions, issue tracking, and a structure for users to follow and contribute to the ecosystem
