Output duration
Podcasts: up to 240 seconds; other scenarios: up to 120 seconds per requestSource for Output duration (opens in a new tab)
Reference audio
Up to 3 clips; each ≤30 seconds and ≤10 MB; WAV, MP3 or OGG OpusSource for Reference audio (opens in a new tab)

Raw PCM input is unsupported. Provide a publicly accessible URL or Base64 data per clip, never both.

Voice references
@voice1, @voice2 and @voice3 refer to clips in list orderSource for Voice references (opens in a new tab)

System/cloned voice IDs are not accepted; supply reference clips directly.

Output formats
WAV, MP3, PCMSource for Output formats (opens in a new tab)

Opus is accepted as a reference format but is not supported for output.

Audio sample rates
8000, 16000, 24000, 44100, 48000Source for Audio sample rates (opens in a new tab)

Hz; default 48,000.

Audio channels
Mono or stereo; default stereoSource for Audio channels (opens in a new tab)
Voice controls
Volume 0–100; speech rate 0.5–2.0; MP3 CBR or VBR settingsSource for Voice controls (opens in a new tab)

MP3 bitrate bounds depend on sample rate; not every integer within those bounds is supported.

Seed control
Request-level integer seed; default 42Source for Seed control (opens in a new tab)

No guaranteed reproducibility or numeric seed bounds are stated.

Request mode
Synchronous HTTPS; download the completed audio file from the result URLSource for Request mode (opens in a new tab)
Result and task expiry
Audio download URL valid for 24 hoursSource for Result and task expiry (opens in a new tab)

Link expiry is not a general data-deletion guarantee.

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

Card and pricing table agree on token billing. The general audio-generation guide still describes duration billing; the API states usage.duration is not used for token charges.

Data retention
Standard API inference prompts and responses are retained for up to 30 days, subject to legal/security exceptions; stateful files remain until deleted. The ZDR roster lists the 3.1 TTS family but does not explicitly name Next; coverage of its generated-file route requires confirmation. Eligibility is opt-in, not a default guarantee.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.

Rate conditions

  1. Original Beijing list rate. Input and output charged separately. The pricing table corroborates token billing, while the general guide has a conflicting duration statement. No generic text-question quote or seconds-to-token conversion is inferred.

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 distinct hosted release selector, official deployment documentation and reviewed Qwen/FunAudioLLM public-weight inventories. No corresponding weights or mapping to a published checkpoint were verified. This classification applies to the hosted tier, not to the public CosyVoice or Qwen model family. Private lineage and parameter counts remain undisclosed.
