API aliases
viduq2Source for API aliases (opens in a new tab)

This selector is scoped to reference2image. The same string on a video route is not the same image contract.

Maximum prompt characters
2,000Source for Maximum prompt characters (opens in a new tab)
Reference images
0–7 imagesSource for Reference images (opens in a new tab)
Image input limits
At least 128 × 128 pixels; provider states up to 50M per image, with a separate 20 MB HTTP body limit.Source for Image input limits (opens in a new tab)

The aspect-ratio wording is ambiguous: “less than 1:4 or 4:1.” Do not treat that sentence as a verified mathematical boundary.

Maximum request body
20 MB HTTP POST bodySource for Maximum request body (opens in a new tab)
Input image formats
PNG, JPEG, JPG, WEBPSource for Input image formats (opens in a new tab)
Input media transport
Accessible image URLs or Base64 with a content-type prefix.Source for Input media transport (opens in a new tab)
Output resolutions
1080p, 2K, 4KSource for Output resolutions (opens in a new tab)

1080p is the default. Exact pixel dimensions and guaranteed output encoding are not specified in this reference.

Aspect ratios
auto, 16:9, 9:16, 1:1, 3:4, 4:3, 21:9, 2:3, 3:2Source for Aspect ratios (opens in a new tab)

Default 16:9. auto uses the first input image; no-image behavior for auto is not documented.

Seed control
Integer seed; omitted or 0 selects a random seed. No supported numeric range or deterministic-output guarantee is published.Source for Seed control (opens in a new tab)
Asynchronous generation
SupportedSource for Asynchronous generation (opens in a new tab)
Request mode
Submit an asynchronous reference2image task, then query /ent/v2/tasks/{id}/creations. Optional signed callbacks report processing, success or failure.Source for Request mode (opens in a new tab)
Task callbacks
Terminal success/failure callback delivery is retried up to three times when delivery fails. See provider callback-signature documentation.Source for Task callbacks (opens in a new tab)
Pass-through payload limit
Optional payload is passed through without processing; maximum 1,048,576 characters.Source for Pass-through payload limit (opens in a new tab)
Output link expiry
Creation URL, cover URL and watermarked URL are valid for 24 hours. This is link expiry, not a guarantee that provider-stored content is deleted.Source for Output link expiry (opens in a new tab)
Request quotas
Default five concurrent tasks per organization, shared across API keys; excess tasks queue. Plan-specific concurrency and system load can change effective availability.Source for Request quotas (opens in a new tab)
Usage metering
Image generation is billed in credits per image, varying by resolution and reference-image count. No token or per-question tariff.Source for Usage metering (opens in a new tab)
Published price
Mainland schedule: 6–30 credits per image depending on resolution and references; CNY 0.03125 per credit.Source for Published price (opens in a new tab)
Pricing discrepancy
Current international pricing labels images q3-lite, q3-fast, q2-pro and q2-fast, while the direct API reference names viduq2 and viduq1. Exact selector mapping is unverified; no USD price is assigned to these q1/q2 records.Source for Pricing discrepancy (opens in a new tab)

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

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.
