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 the long-context tier of $4 input / $0.20 cached input / $5 cache write / $15 output per 1M. Short-context cache writes bill at $2.50 per 1M. Batch is half the Standard rate ($1 / $0.05 / $1.25 / $5). Regional (data-residency) endpoints carry a 10% uplift.
