Caching

Caching can reuse earlier input processing. Availability, lifetime and billing depend on the endpoint. A cache hit still generates a new response.

01 / INITIAL INPUTProcess & retain

The system processes eligible input and retains reusable state.

02 / LATER REQUESTCheck available state

Reuse depends on matching input, session state and the cache policy.

03 / CACHE HITReuse & generate

Reusing state can reduce repeated work. Any charges follow the billing rules below.

How it works
Implicit caching; explicit cache objects on eligible GenerateContent calls.Source for How it works (opens in a new tab)
Minimum reusable input
Not collected
Lifetime & refresh
Explicit objects default to 1 hour; set ttl or expire_time, update or delete the object. The implicit cache lifetime is not specified in this guide.Source for Lifetime & refresh (opens in a new tab)
How to enable it
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)
Usage fields
Interactions: usage.total_cached_tokens. GenerateContent: usage_metadata reports cached tokens.Source for Usage fields (opens in a new tab)
Billing rules
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)

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.

The record behind the model

Why it is included
