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
Hosted API; account and API key required. No generation was submitted.

Required request fields

OpenAPI required-field list; conditional requirements in property descriptions are recorded separately.

Request quotas

Asynchronous generation
Asynchronous by default. Try-Sync=true waits up to 60 seconds; a prediction ID and status URL support longer jobs.Source for Asynchronous generation (opens in a new tab)
Result retrieval
GET /v1/predictions/status/{id}; download the result from the returned URL.Source for Result retrieval (opens in a new tab)
Reference guidance
Single-image mode uses image and prompt. When images is set, image is ignored and the request returns a results list. Per-image prompts must match images length; otherwise the shared prompt is reused.Source for Reference guidance (opens in a new tab)
Input limits
Not collected

No array maximum, image byte/resolution limit or prompt length bound established. Schema does not declare conditional fields required, though property descriptions require a prompt in single-image mode.

How to interpret scores
Not collected

Score names, numerical range, thresholds and underlying evaluator/checkpoint are not published in the reviewed schema.

Pricing coverage
Not collected

No verified P-Judger tariff. Image-generation prices must not be substituted.

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

Data & enterprise terms

Pruna API terms retain customer ownership of input/output and permit processing to provide the service. Operational telemetry is used for security and service improvement. A universal retention period and zero-training guarantee are not established.

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

Named hosted image-processing component. The exact underlying checkpoint and private-weight provenance are not established; this is explicitly a managed service record, not an additional claimed private foundation checkpoint.
