OpenAI adds 12-hour prompt caching option to its API
AIOpenAI says developers can now choose 12-hour prompt caching in the API, which keeps shared instructions, tools, and context cached longer, even when requests are hours apart. The longer cache keeps cached-input pricing available across that window, and 12-hour cache writes cost 2.5x the input token price.
