PHYSIX OBSERVATION

By locking its fastest model behind the $500 tier, OpenAI is effectively using speed as a tiered pricing lever, splitting high-frequency professional users from ordinary subscribers. For developers, 8x speed in scenarios like Codex can save considerable waiting time, but the monthly fee threshold also means frontier capability is rapidly becoming a paid privilege, and the experience gap between free or low-cost tiers will only widen.
