Rate conditions

  1. 4 API credits per second. Round audio duration up to whole seconds. Calculated PAYG equivalent using the published $10 / 2,000-credit pack ($0.005 per credit). Membership credits have different effective rates; API credits are separate from the web app. The pricing page’s video-count examples are inconsistent and are not used in this calculation.
  2. 4 API credits per 15 UTF-8 bytes. Round up the UTF-8 encoded script length in 15-byte units. This is not 15 characters or tokens. Calculated PAYG equivalent using the published $10 / 2,000-credit pack ($0.005 per credit). Membership credits have different effective rates; API credits are separate from the web app. The pricing page’s video-count examples are inconsistent and are not used in this calculation.

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

Managed production service in the official PixVerse video API. No downloadable production weights or open-weight license for this exact service were established. This is not an assertion of a separately disclosed foundation checkpoint; internal composition is not pinned.
