How this price is scoped: OpenAI's rate card prices this model by context length: the tracked figure is the short-context tier (prompts up to 272K input tokens), and longer prompts bill at 2x input and cache rates and 1.5x output for the full request ($2 input / $0.10 cached input / $2.50 cache write / $7.50 output per 1M). Short-context cache writes bill at $1.25 per 1M for 30-minute retention and $2.50 for 12-hour retention. Batch and Flex are half the Standard rate ($0.50 / $0.025 / $0.625 / $2.50); the Fast tier is double ($2 / $0.10 / $2.50 / $10). Regional (data-residency) endpoints carry a 10% uplift.
