That's great if they actually work. But my experience with the big, corporate-funded models has been pretty freaking abysmal after more than a year of trying to adopt them into my daily workflow. I can't imagine the performance of local models is better when they're running on much, much smaller datasets and with much, much less computing power.
I'm happy to be proven wrong, of course, but I just don't see how it's possible for local models to compete with the Big Boys in terms of quality... and the quality of the largest models is only middling at best.
