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 INPUT Process & retain The system processes eligible input and retains reusable state.
02 / LATER REQUEST Check available state Reuse depends on matching input, session state and the cache policy.
03 / CACHE HIT Reuse & generate Reusing state can reduce repeated work. Any charges follow the billing rules below.
enable_cached_responses is accepted but currently ignored; marked coming soon.

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 Inferred for this exact native API release/service from provider documentation and review of Sarvam’s public weight inventory. No weights for this identity were identified. Public Sarvam language/translation weights and hosted third-party weights are excluded. A named service or version does not establish an independently disclosed checkpoint.
