PHYSIX OBSERVATION

The mid-tier market is the real battleground for AI commercialization, and the price war has already spread from closed-source to open-source. Enterprises buy intelligence per dollar, and frontier models' share keeps shrinking. It's good for users, but for vendors it means surviving on scale or vertical integration alone.
