Output resolutions
Up to 4KSource for Output resolutions (opens in a new tab)

Model capability: 1080p generation followed by a distilled refinement/upscale stage for 4K. App export resolution depends on the subscription.

Generation controls
Find first for review or Smooth all; five cuts processed at a time, remaining cuts queuedSource for Generation controls (opens in a new tab)

This UI work queue is not proof of a discounted batch-inference API.

Input requirements
Complete rough edits first. Multitrack sequences support audio smoothing only.Source for Input requirements (opens in a new tab)
Usage metering
Shared AI-credit allowance; exact feature cost depends on the operationSource for Usage metering (opens in a new tab)

Media imports/recordings use separate media minutes. Subscription credits do not roll over. A subscription price is not a per-inference rate.

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 standalone model API ID is published for this editing feature.

Access
Use Smooth jump cuts in the AI tools panel; review identified cuts or smooth all, with audio/video or audio-only output.
Regions
Managed service; exact model-processing region not verified

Billing basis
Manual effects scale with job size. Underlord charges separately for its agent reasoning and the tools it invokes; identical prompts can use different credit amounts.Source for Billing basis (opens in a new tab)
Included plan allowances
Hobbyist: 400 AI credits + 10 media hours per editor/month, Creator: 800 AI credits + 30 media hours per editor/month, Business: 1,500 AI credits + 40 media hours per editor/month, Free: 100 one-time AI credits + 1 media hour/month; limited feature trialsSource for Included plan allowances (opens in a new tab)

Editor seats contribute to a shared Drive pool. Enterprise has custom allowances. Plan limits and export resolution are not model context/output limits.

Rate conditions

  1. Shared editor subscription including credit/media allowances and other features; AI operations consume credits. Not a flat per-model or per-question price.
  2. Monthly-equivalent shared subscription with annual commitment. Included monthly credits do not roll over. Not an independent inference tariff.
  3. Creator/Business only. Shared across the Drive, expires 12 months after purchase, consumed after monthly allowance. Credit cost of an operation varies; do not convert this into a universal media-minute rate.

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.

API model ID
Not collected

No standalone model API ID is published for this editing feature.

Access
Paid Descript users can ask Underlord to edit a project. This is agent-orchestrated access, not a dedicated or pinned media-model endpoint.
Regions
Managed service; exact model-processing region not verified
API endpoint URL
POST https://descriptapi.com/v1/jobs/agent; poll GET /v1/jobs/{job_id}Source for API endpoint URL (opens in a new tab)
Authentication
Authorization: Bearer personal token, scoped to a Drive and inheriting its permissionsSource for Authentication (opens in a new tab)
Request limits
Supply exactly one of project_id or project_name; optional composition_id requires project_id. Callback URL supports completion/failure notifications.Source for Request limits (opens in a new tab)
Model routing
model selects the editing agent’s LLM, not this media model. GET /agent/models is authenticated and dynamic; documentation examples are not the full available catalog.Source for Model routing (opens in a new tab)
Request quotas
On HTTP 429 respect Retry-After; response also exposes remaining/consumed quota headers. No numeric fixed quota collected.Source for Request quotas (opens in a new tab)
Billing basis
No additional API access fee for paying users; operations use the account’s AI credits and media minutes. Agent reasoning and the tool are both metered.Source for Billing basis (opens in a new tab)

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

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

Descript identifies its media-editing models as proprietary and reserves service/model rights. The record is a documented proprietary model generation or explicitly labeled managed enhancement family; project-page code is not released model weights. Separately downloadable DAC and Mouse research weights are excluded.
