Availability
Announced family; operational availability unverified. Public playground source explicitly says its backend endpoints do not exist yet, and the inspected repository tree has no playground handlers. The live deployment may differ. Terms describe active development and demonstration/evaluation use; no inference was attempted.Source for Availability (opens in a new tab)
Family display name and UI route are not immutable native checkpoint IDs.
Access
Contact-sales offering. Public source proposes /api/playground/transcribe but explicitly says handlers do not yet exist. This is not a verified callable API. Live deployment parity unverified.
Regions
No production inference region established. Public-service privacy mentions transfers to Niger, United States and provider countries.

Rate conditions
Model-page advertised rate. Public source describes unimplemented playground handlers; actual service availability, billing rounding, minimum charges, taxes and plan conditions unverified. Not a token price or a verified production quote.
Reviewed privacy policy covers the public website and Playground and explicitly excludes unreleased products. Training/evaluation use is permitted with permission or where otherwise allowed by law, with withdrawal and deletion requests. Retention is purpose-based without an exact TTL. Transfers may involve Niger, the United States and other provider countries. This is not a blanket no-training, zero-retention or production API residency guarantee.
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
Read-speech word error rate
Namu · Provider-reported; not independently verified
8.4% WER
Clean read Hausa speech; corpus, normalization rules, test size and dialect breakdown not published. Lower is better. No complete evaluation artifact, versioned serving checkpoint or independently reproduced result reviewed. Operational availability remains unverified.
Namu · Provider-reported; not independently verified
14.1% WER
Market and street recordings; corpus, normalization and test size not published. Lower is better. No complete evaluation artifact, versioned serving checkpoint or independently reproduced result reviewed. Operational availability remains unverified.
Namu · Provider-reported; not independently verified
11× real time
Batch, single GPU; GPU type, batch size and recording lengths not specified. Not a batch API contract. No complete evaluation artifact, versioned serving checkpoint or independently reproduced result reviewed. Operational availability remains unverified.
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
Named proprietary service family advertised under Namu service terms, which reserve technology rights and prohibit extracting weights. A private native checkpoint and its ancestry have not been established. Kept as a managed family, not a verified closed-weight foundation-model release; public Tiny Aya and educational MMS derivatives are separate projects.
