No, the inference/training algorithms, being math, are not copyrightable. OP just wrote another implementation. What's copyrighted are the models, which OP did not train from scratch (having neither the training material nor the compute to do that).
Is upstream dependency licensure necessary to establish copyright? For example, I Need a Haircut was still a unique work regardless of the rights to sample Alone Again.
I mean, if you take a match to a blank CD-ROM, or shoot neutrinos at a USB drive, there is a very small chance that you get the SD weights stored on them
The code outlining the network vs. the resultant weights. (Also vs. any training, inference, fine tuning, misc support code, etc.)
The theoretical diagram of how the code networks and modules are connected is math. But an implementation of that in code is copyrightable.
Afaik, the weights are still a grey area. Whereas code is code and is copyrightable.
Weights are not produced by humans. They are the result of an automated process and are not afforded copyright protection. But this hasn't been tested in court.
If OpenAI GPT 4o weights leak, I think the whole world could use it for free. You'd just have to write the code to run them yourself.
