Interactions supports implicit caching only. For explicit caching, create a cache with the GenerateContent API and pass its name as cached_content.Source for How to enable it (opens in a new tab)
Reads use the cached-input rate. Explicit cache storage is billed per million tokens per hour, in addition to generation. Free-tier eligibility and audio rates vary by model.Source for Billing rules (opens in a new tab)
Limits & data boundaries
Cached content is a prompt prefix and counts toward the input limit. Implicit hits are not guaranteed. Explicit caching uses GenerateContent v1beta; API and model eligibility must match.Source for Limits & data boundaries (opens in a new tab)
No verified cache rate for this endpoint. An empty rate is not a zero charge.

What the measurements say
No benchmark observations have been added for this model. We do not turn a vendor description into a performance score.
Latency and throughput depend on the host, request size, reasoning settings and load. There is no measured speed or global usage figure in this record.
