model plus input.messages containing exactly one message. At least one non-empty text field is required; the first non-empty text is used as prompt, and all image fields are references.Source for Required request fields (opens in a new tab)
n accepts only 1. Field table marks n optional, but a failure example calls it required; explicitly supplying n=1 avoids relying on the inconsistent default.
Only the enumerated presets are documented; default 1024*1024. Tier names do not imply a fixed long-edge dimension.
Seed control
Integer from 0 through 2,147,483,647; 0 or omission chooses a random seed. Repeated seeds are described as yielding similar outputs, not guaranteed identical images.Source for Seed control (opens in a new tab)

Rate conditions
Original Beijing CNY rate per output image, excluding limited-time promotions. Only output is billed; no free quota. Pricing labels the first tier 1080P, while the API size table calls it 1K; do not replace explicit dimensions with a 1080-pixel assumption.

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
Qualified classification inference: native Vidu service/variant with restricted API access; operator terms reserve proprietary service rights and prohibit reverse engineering. No exact downloadable checkpoint is identified in reviewed primary documentation. This is not proof of private weights, or of distinct checkpoint lineage between similarly named hosted variants.
