Specifications

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

Input token limit
1,024 tokensSource for Input token limit (opens in a new tab)

Text-input token limit; not a video duration or a general chat context.

Maximum output

Videos per request
1 video per requestSource for Videos per request (opens in a new tab)
Output resolutions
720p, 1080p, 4KSource for Output resolutions (opens in a new tab)

These resolutions have separate rates.

Video duration
4, 6 or 8 secondsSource for Video duration (opens in a new tab)

1080p and 4K (where supported) require 8 seconds. On models supporting reference images, those requests also require 8 seconds.

Frame controls
First and last frame interpolationSource for Frame controls (opens in a new tab)
Video extension
SupportedSource for Video extension (opens in a new tab)

Uses a video from a prior generation; extension is limited to 720p.

Context caching
Not collected

See endpoint caching records. No verified support claim for this model.

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

Access
Google AI Studio / Gemini API account; region, tier and quota restrictions apply.
Regions
See Google supported-region and account requirements; region-specific availability not yet collected.

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: Veo 3.1. 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
Veo 3.1Source 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.
