There isn't any open-source AI. There is Open AI (not to be confused with the closed company called OpenAI, which was unable to trademark its name). There's no open source AI both because the open source community doesn't have the resources to train a useful AI and because AI doesn't have source code.
Is training code and dataset not source?
Are they open?
I’m just challenging your point that ai doesn’t have source.
This is just wrong on multiple levels, the open source model ecosystem is very much a thing.
I don't know of any useful model that would match the usual definition of "open source". That is, where everything needed to build the thing is provided, such as the training data and code. Not that it would be tremendously useful anyways considering how expensive training a model is.
I much prefer the "open weights" term. It is not open source in the sense that you only get the finished product, not the actual source, but it is still open in the sense that it is not only accessible as a service.
For an analogy, take Quake for instance. When it was launched, its game server was available as an executable, so you could run it your machine, but that didn't make it open source. Only much later it was released as true open source software.
There are fully open models, it's just not as common because that's basically giving away the sauce, which is non-viable for many.
