I take your points, but I think the trend cuts both ways. Open source never really dies. So paying a modest annual fee for a strong local model — not the latest frontier model, but still very capable — seems perfectly plausible.
I also don’t buy the idea that free models are just tasters. We’re in an AI arms race. Open releases help stop one company becoming too dominant, while building ecosystems, adoption and hardware demand.
The very best models may remain closed, but strong local models being open or low-cost feels more likely than local AI fading away.
