I'm sorry if I was unclear the first two times I asked, but when I said:
care to link me to all these great models from academics and open-source institutions?
I was interested in the models you're currently using, not the ones you're speculating about. Hopefully it goes without saying that "open" weights are precompiled closed-source blobs, and "Open"AI is anything but, etc.
I'm aware new models are trained at the speed of light and hardware is going obsolete faster than it can be put on racks, which is already a problem, so I would love to believe your theory about inexpensive AI GPUs but those very same companies are already going into debt without selling their current stock.
Edit: we have a reason to not assume GPUs will suddenly become cheap.
