"open source" has come to mean "open weight" in model land. It is what it is. Words are used for communication, you are the one misusing the words.
You can update the weights of the model, continue to train, whatever. Nobody is stopping you.
- a-dub 11mo agoit still doesn't sit right. sure it's different in terms of mutability from say, compiled software programs, but it still remains not end to end reproducible and available for inspection. these words had meaning long before "model land" became a thing. overloading them is just confusing for everyone.
- danielmarkbruce 11mo agoIt's not confusing, no one is really confused except the people upset that the meaning is different in a different context. On top of that, in many cases a company/group/whoever can't even reproduce the model themselves. There are lots of sources of non-determinism even if folks are doing things in a very buttoned up manner. And, when you are training on trillions of tokens, you are likely training on some awful sounding stuff - "Facebook is trained llama 4 on nazi propaganda!" is not what they want to see published. How about just being thankful?
- a-dub 11mo agoi disagree. words matter. the whole point of open source is that anyone can look and see exactly how the sausage is made. that is the point. that is why the word "open" is used. ...and sure, compiling gcc is nondeterministic too, but i can still inspect the complete source from where it comes because it is open source, which means that all of the source materials are available for inspection.
- danielmarkbruce 11mo agoThe point of open source in software is as you say. It's just not the same thing though. Using words and phrases differently in different fields is common.
- a-dub 11mo ago...and my point is that it should be. the practice of science itself would be far stronger if it took more pages from open source software culture.
- h33t-l4x0r 11mo agoI agree that they should say "open weight" instead of "open source" when that's what they mean, but it might take some time for people to understand that it's not the same thing exactly and we should allow some slack for that.
- a-dub 11mo agono. truly open source models are wonderful and remarkable things that truly move the needle in education, understanding, distributed collaboration and the advancement of the state of the art. redefinition of the terminology reduces incentive to strive for the wonderful goal that they represent.
- HarHarVeryFunny 11mo agoThere is a big difference between open source for something like the linux kernel or gcc where anyone with a home PC can build it, and any non-trivial LLM where it takes cloud compute and costs a lot to train it. No hobbyist or educational institution is going to be paying for million dollar training runs, probably not even thousand dollar ones.
- a-dub 11mo ago"too big to share." nope. sharing the finished soup base, even if well suited for inclusion in other recipes, is still different from sharing the complete recipe. sharing the complete recipe encourages innovation in soup bases, including bringing the cost down for making them from scratch.
- mensetmanusman 11mo agoWeights are meaningless without training data and source.
- antiframe 11mo agoI get a lot of meaning out of weights and source (without the training data), not sure about you. Calling it meaningless seems like exaggeration.
- mensetmanusman 11mo agoCan you change the weights to improve?
- HarHarVeryFunny 11mo agoYou can fine tune without the original training data, which for a large LLM is typically going to mean using LoRA - keeping the original weights unchanged and adding separate fine-tuning weights.
- danielmarkbruce 11mo agoit's a bunch of numbers. Of course you can change them.
