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 the share of frontier models keeps shrinking. It is good news for users, but for vendors it means surviving only through scale or vertical integration.
