Access & pricing

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

Topaz Labs API

Provider source (opens in a new tab)
API model ID

Access
API-key authenticated https://api.topazlabs.com/image/v1/sharpen/async. Processing consumes credits; no paid call was performed during review.
Regions
Processing region not established in reviewed model documentation.
Request size limit
500 MB request-body limitSource for Request size limit (opens in a new tab)

This is an API request limit. The multipart video upload workflow does not establish a universal 500 MB maximum source-video file.

Request quotas
Load-dependent; HTTP 429 responses require retry/backoff. No fixed account RPM limit established.Source for Request quotas (opens in a new tab)
Processing workflow
Asynchronous image processing with an API key.Source for Processing workflow (opens in a new tab)
Model controls
denoiseStrength — decimal between 0 and 1, default 0.5, faceEnhancement — boolean, faceEnhancementStrength — decimal between 0 and 1, faceEnhancementCreativity — decimal between 0 and 1, subjectDetection — "All" , "Foreground" , or "Background", sharpenStrength — decimal between 0 and 1, default 0.5, opacity — decimal between 0 and 1, default 1.0Source for Model controls (opens in a new tab)

Exact documented field names and type/range lines; optional descriptions are omitted. These controls are not weight fine-tuning.

Training data policy
Not collected

The reviewed general privacy policy does not establish a model-specific prohibition on training use.

Data retention
Not collected

No precise uploaded-media retention duration established for this model.

Content provenance
Provider FAQ says API outputs are C2PA-compliant.Source for Content provenance (opens in a new tab)

Provider statement, not an independently verified credential check.

Input file formats

API model ID
Not collected

The application documents a UI model name, not an exact API checkpoint selector.

Access
Local processing in the licensed desktop application. Hardware and app-version restrictions apply.
Regions
Local computer; hardware compatibility applies.
Billing basis
Not collected

Commercial application access; no independent numeric model tariff established. API credit prices do not determine this app’s cost.

Recommended source
Images of at least 5 MP with low or moderate blur, after denoising and other corrections.Source for Recommended source (opens in a new tab)

Recommendation for texture-preserving finishing, not a minimum accepted API size.

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

Data & enterprise terms

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

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

The provider identifies these as its internally developed AI models. Its published proprietary software terms retain intellectual-property rights and prohibit redistribution and reverse engineering. API selectors are recorded without claiming the weights are openly licensed.
