The popularity of fine-tuning demonstrates that the weights are actually the preferred form for making changes.

The precursor form (training data etc) is only needed if you want to recreate it from scratch. Which is too expensive to bother with.

My point is, wanting a finished product that cost millions, without paying for it, is very different than it being open sourced. Models are an artifact, a result, not a source.

I would argue that the weights are as much source code as source code. Them being generated doesn't demote them.

I don't even think the distinction is important. The "system" should be open, and that includes data central to the system's operation within certain bounds.

You can open source parts of a system at whichever fine slice you wish, you just have the part which is open A and the part which isn't B.

It's the value of A and B being open that matters, not what A and B are composed of.

Great point. Open source is different from free product.
