This means you can achieve significantly higher effective throughput by using prompt caching.  To make the most of your rate limits, cache repeated content such as system instructions and prompts, large context documents, tool definitions, and conversation history; see prompt caching for guidance. With effective caching, you can substantially increase your actual throughput without raising your rate limits. Monitor your cache hit rate on the Usage page to tune your caching strategy.@@ -114,17 +114,19 @@ Rate limits are currently shared across all `inference_geo` values.
