I think you're misunderstanding what I'm saying. I don't think its technically feasible for current models to be open source, because there is no source code to open. Yes, there is a harness that runs the model, but the vast, vast amount of instructions are contained in the model weights, which are akin to a compiled binary.

If we make large strides in interpretability we may have something resembling source code, but we're certainly not there yet. I don't think the solution to that problem should be to change the definition of open source and pretend the problem has been solved.
