This isn’t open source. It s the equivalent of headers being available to a dylib, just that they happen to be a python API. Most of the magic is behind closed source components, and it’s posted with a fairly restrictive license.

And people say nvida doesn't have a moat.

  donno. it's clear they have no effective moat. they still try hard, making themselves quite customer-hostile.

    CUDA is a moat. What's ineffective about it?

In a similar fashion, you'll see that JAX has frontend code being open-sourced, while device-related code is distributed as binaries. For example, if you're on Google's TPU, you'll see libtpu.so, and on macOS, you'll see pjrt_plugin_metal_1.x.dylib. The main optimizations (scheduler, vectorizer, etc.) are hidden behind these shared libraries. If open-sourced, they might reveal hints about proprietary algorithms and provide clues to various hardware components, which could potentially be exploited.
