The route, job ID, voice ID or avatar ID does not identify a native serving checkpoint.
Access
POST https://openapi.akool.com/api/open/v3/content/video/createbytranslate. Authenticate with x-api-key or Bearer authorization. Account, plan and feature availability apply.
Regions
Published personal-data storage: AWS in the EEA or United States unless otherwise specified. This is not a guarantee of a selectable inference region.
Customer Content is stored for 365 days and users can clear it; other data categories and contractual/legal exceptions have separate retention rules.Source for Data retention (opens in a new tab)
duration
Current createbytranslate validation does not impose a 60-second limit; under 60 seconds is a recommendation. The separate legacy /content/video/translate endpoint rejects longer videos. Downstream constraints may still apply.Source for duration (opens in a new tab)
voiceSelection
Original-voice cloning for exact codes: en fr zh ar bg hr cs da nl fil fi de el hi hu id it ja ko ms nb pl pt ro ru sk es sv ta tr uk vi. Other codes use AI voices; zh-CN differs from zh. Server overrides voices_map.voice_type; voice_id is optional in current validation.Source for voiceSelection (opens in a new tab)
controls
Comma-separated targets without spaces; automatic source language and speaker detection. Lip sync defaults false. SRT/ASS subtitles, caption modes 0–4, terminology/pronunciation mappings, background-music removal and dynamic duration. merge_interval and face_enhance are deprecated.Source for controls (opens in a new tab)

Rate conditions
Explicitly labeled limited-time; Pro Max and Business. No expiry date or permanent post-promotion rate established.
Terms state customer content and usage data will not be used by Akool or third parties to train machine-learning models. Privacy policy gives Customer Content a 365-day retention period with user deletion, and AWS storage in the EEA or US unless otherwise specified. Generated-resource expiry is separate from storage retention. Contract-specific and legal exceptions apply.
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
Documented named hosted service, product or voice-engine selector. The underlying native checkpoint is undisclosed or explicitly supplied by a third party, so this record does not assert independent proprietary Akool weights.
