An llm isn't software any more than a matrix is.
What do you think an open source matrix should look like?
What do you think an open source matrix should look like?
Its about reproducibility and modifiability. Compiled executables (and their licences) lack that. The same as these downloadable blobs.
You can absolutely have open source machine code.
The issue is and always has been that you need to have access to the same level of abstraction as the people writing the source code. The GPL specifically bans transpilers as a way to get around this.
In ML there is _no_ level of abstraction other than the raw weights. Everything else is support machinery no different to an compiler, and os, or a physical computer to run the code on.
Linux isn't closed source because they don't ship a C compiler with their code. Why should llama models be any different?
I'm not even necessarily advocating that these things should be released, but the term "open source" has a pretty well-understood meaning that is being equivocated here.
