The research repository reports 7.7B for its closed Fun-ASR evaluation model and 800M for public Nano models. Exact mapping to this hosted selector is not established.
Chinese dialect/accent coverage is model-specific. Stable Realtime and its February 2026 snapshot have different published language rosters.

Data retention
Standard API inference prompts and responses are retained up to 30 days, subject to legal/security exceptions; stateful files remain until deleted. Fun-ASR is absent from the published ZDR-supported model roster. Result URL expiry is not a general deletion guarantee.Source for Data retention (opens in a new tab)

Rate conditions
Original regional list rate; transcription output has no separate charge. File transcription bills each requested track separately. Free quotas and promotional rates are separate; no generic text-question estimate.

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
The official Fun-ASR repository explicitly labels its evaluated 7.7B Fun-ASR model as not open-source, separately from public 800M Nano checkpoints. Hosted release cards and API selectors establish these service identities. Extending family-level closed-weight classification to each private revision is an inference; exact research-checkpoint mapping and parameter counts are not copied onto every hosted release.
