PromptCacheOptions - OpenRouter

Request-level prompt-cache controls. mode: "explicit" disables OpenAI-managed breakpoints so only blocks marked with prompt_cache_breakpoint are cached. ttl sets the minimum cache lifetime for every breakpoint the request writes: “30m” (default) or “12h” (billed at the higher 12h cache-write rate). Only supported by OpenAI GPT-5.6 and newer.

Example Usage

import { PromptCacheOptions } from "@openrouter/sdk/models";

let value: PromptCacheOptions = {
  mode: "explicit",
};
