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)

Current service policy, not proof of deletion timing for past calls.

Access & pricing

Prices belong to an endpoint and billing tier. A provider listing does not guarantee access for every account or region.

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.

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.
