Specifications

Provider-documented facts. “Not collected” means we have not verified that field yet, not that the feature is unsupported.

Reasoning
Not collected
Streaming
Not supportedSource for Streaming (opens in a new tab)

Returns a task ID; retrieve the completed transcript by polling. Asynchronous processing is not streaming or discounted batch inference.

Usage metering
Separate input and output token chargesSource for Usage metering (opens in a new tab)

Input audio, supplied context and result tokens must be accounted for under the specific API. No text-only per-question estimate is inferred.

Custom vocabulary
SupportedSource for Custom vocabulary (opens in a new tab)

Precompiled and inline hotword support; limits and weighting are endpoint-specific.

Audio duration limits
Up to 12 hours per fileSource for Audio duration limits (opens in a new tab)

With speaker diarization, the guide recommends staying within two hours to avoid failure or timeout.

Maximum audio file
2 GB; one input URL per taskSource for Maximum audio file (opens in a new tab)
Request mode
Asynchronous HTTP task; poll for completed transcriptSource for Request mode (opens in a new tab)

parameters is required even when empty; X-DashScope-Async: enable is required.

Result and task expiry
Result download URL and task query valid for 24 hoursSource for Result and task expiry (opens in a new tab)

Not a general deletion or zero-retention guarantee.

Supplied context limit
Up to 5 user and 5 assistant context messages; combined text ≤400 characters per turnSource for Supplied context limit (opens in a new tab)

Keep each user context message before its matching assistant message; overflow is truncated.

Dialect transcription controls
Preserve dialect expressions or normalize them to standard MandarinSource for Dialect transcription controls (opens in a new tab)

Controlled by keep_dialect; the default is false.

Data retention
Standard API inference prompts and responses are retained up to 30 days, subject to legal/security exceptions; stateful files remain until deleted. The 3.1 ASR family is listed for opt-in ZDR, but asynchronous task management is explicitly excluded; this Filetrans path is not covered.Source for Data retention (opens in a new tab)

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

Inference from the release-specific hosted Model Studio identity, official technical/deployment documentation and reviewed Qwen/FunAudioLLM public-weight inventories. No matching weights are published in those inventories. Public Qwen-Audio, Qwen3-TTS, Qwen3-ASR, CosyVoice and Fun-ASR checkpoints have distinct names; no equivalence with this hosted selector is assumed. This is not a claim that the whole family or all Alibaba models are closed-weight.
