Frontier AI you can hold, inspect, and run yourself.
We take models that only work inside someone else's walls and make them run in the open, on hardware you own. Every release ships with the recipe, so you can rebuild it, or build your own.
The repack tool and the build pipeline are open: deepseek-v41-upstream on GitHub. Bring any DeepSeek-V4.1-Flash checkpoint, a fine-tune, a merge, your own variant, and get a one-card file in the same size class.
The open engine everyone depends on is only as good as what people put back into it. This is our part. More in Why We're on Hugging Face.
