DeepSeek has released a ton of low-level AI infrastructure code, libraries, and mathematical models on GitHub. Their tools and agent environments are fully open sourced including their harness. They release complete PyTorch and Hugging-face compatible python files detailing their configuration, tokenizers, and layers of the architecture.
The only thing they don't release is their data-filtering pipelines but they detail even that in their public-access papers.
DeepSeek is truly as open source as you can possibly legally get. Besides the data itself, it's completely reproducible by anyone else.
I don't think americans yet acknowledge just how radically transparent Chinese labs are being (and how much even the west benefits from it).
