Global Frontier LLM API Pricing × Token Structure (June 2026)
One ruler for 20 high-traffic frontier LLMs: Chinese models average ~6–9x cheaper than US ones — yet input dwarfs output by tens of times and cache covers 50–94% of input, so the bill is driven by input & cache pricing, not the headline output price. Full price × token-structure table and a cost-formula breakdown included.
