Access & pricing

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

API model ID
Not collected

No distinct public model selector established for this route.

Access
Authenticated Kling API account and eligible balance/package. New and legacy authentication requirements vary by route.
Regions
Public examples use api-singapore.klingai.com; this hostname does not establish contractual data residency.
API endpoint URL
https://api-singapore.klingai.com/v1/videos/avatar/image2videoSource for API endpoint URL (opens in a new tab)
Request limits
Concurrency depends on the account’s active package and is shared across API keys. Image tasks consume slots by image count; querying tasks does not consume concurrency.Source for Request limits (opens in a new tab)
Output link expiry
Generated assets are cleared after 30 days; save output URLs promptly.Source for Output link expiry (opens in a new tab)

Artifact availability only, not a training-use policy or a contractual zero-retention guarantee.

Data & enterprise terms

Retention, training use, regional processing and enterprise terms have not been summarized for this endpoint.

API model ID
Not collected

Descript UI label: Kling Avatar v2. No confirmed native provider API selector or pinned backend checkpoint is exposed by this source.

Access
Choose this model in Descript App Settings → AI models or the applicable generation tool. Availability depends on the plan; exact native provider checkpoint IDs are not exposed.
Regions
Managed service; exact model-processing region not verified
Native model options
Kling Avatar v2Source for Native model options (opens in a new tab)

Application selection label. This access record does not assert that Descript exposes every upstream provider API feature or pins an exact snapshot.

Billing basis
Uses Descript AI credits from a shared plan allowance; exact cost depends on selected model, media length and operation. Provider-native token/character tariffs do not apply to this host.Source for Billing basis (opens in a new tab)
Shared credit bundles
Creator/Business top ups: 350 credits/$35, 1,000/$80, 4,000/$200; valid 12 months and used after included monthly creditsSource for Shared credit bundles (opens in a new tab)

Bundle prices are shared across tools, not a fixed generation price.

Endpoint pricing has not been collected. Check the provider for applicable rates.

Data & enterprise terms

Descript help states that production models use no Descript user data; internal research/development uses data only from users who opted in. Enterprise data sharing is disabled by default. Partner agreements prohibit using submitted data to train partner AI. This is not a blanket zero-retention promise; project storage and deletion have separate policies.

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 exact named production model or managed service in Kuaishou’s official API catalog: no downloadable production weights or open-weight license were established for this identity. Original public-weight Kolors and research derivatives are excluded; public demo code is not evidence of production weights.
