Regions
Automatic routing to Mumbai, India or Oregon, USA; api.india.smallest.ai and api.us.smallest.ai pin a region. Language availability can differ by region.
Content is retained unless an eligible Enterprise data policy is enabled. Options: no content storage, a 24-hour to 90-day window, or x-expire-content: true for seven-day expiry. On other plans the header is ignored. Billing/usage metadata remains; settings are not retroactive. TTS saved history is excluded from window expiry. Speech-to-speech and cloning are not expressly covered.
No pinned inference selector verified for this access route.

Customer-managed infrastructure
Endpoint pricing has not been collected. Check the provider for applicable rates.
Data & enterprise terms
Inference runs on customer infrastructure. A license proxy needs outbound access for license validation and usage reporting; do not assume fully air-gapped operation.
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.

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
Smallest retains rights in its AI models and prohibits model extraction. Its model cards name Smallest as developer; Electron, Hydra and Lightning v3.1 explicitly use proprietary licenses. Commercial self-hosting requires licensed artifacts and a license proxy, not an open-weight grant.
