× official = normalized price ÷ the cheapest official price for the same model and spec. ~ marks a relaxed match: tier, resolution or audio is unspecified on one side, and every compatible official spec costs the same. — = no unambiguous official price to compare.
Confidence: “Pricing page” = read on the provider’s own pricing or docs page; “Pricing API” = read from a public API response. “BYO” tiers are bring-your-own-account estimates, not per-call prices.
China (CNY) list prices (1)
Prices published on Chinese-market platforms in yuan. We do not convert them to dollars because the pages state no exchange rate. The last column divides the CNY price by the international official USD price for the same spec; a value below the market CNY/USD exchange rate means the China list price is lower in dollar terms.
