I don't know if there is one. There are models people can run on fairly expensive hardware at home, but will those be 'good enough' compared to the heavier duty resources that a big, well-funded corporation can deploy?
Like... while the open source models are improving, does that converge with the fancy models with tons of money behind them?
My understanding of the economics of it - so far - is that "more computing resources leads to better results" and capital wins that game.
