Specifications

Provider-documented facts. “Not collected” means we have not verified that field yet, not that the feature is unsupported.

Context / input limit
Not collected
Maximum input tokens

Reasoning

Streaming
SupportedSource for Streaming (opens in a new tab)

Live video is delivered through the SDK session; this is not a text-token SSE interface.

Knowledge cutoff
Not collected
Release date
2026-09-17Source for Release date (opens in a new tab)

Documented International/Global Model Studio availability, not the family’s earlier product-preview date.

Parameters
Not collected
Architecture
Not collected
Languages

Maximum prompt characters
2,000Source for Maximum prompt characters (opens in a new tab)

World theme / synopsis limit in characters, not tokens. Directing script beats have a separate limit.

Image input limits
One required first-frame image; strictly under 6 MB; JPG/JPEG/PNG/WebPSource for Image input limits (opens in a new tab)
Aspect ratios
9:16 (default) or 16:9; reference ratio 0.5–0.667 or 1.5–2.0 respectivelySource for Aspect ratios (opens in a new tab)
Input media transport
Image URL or base64, mutually exclusive for each imageSource for Input media transport (opens in a new tab)
Request mode
Create a world, obtain a Travel ticket, then start an SDK video sessionSource for Request mode (opens in a new tab)

World creation is asynchronous by default. A 120-second creation polling timeout is not a generation-duration limit.

Live session controls
Text instructions, pause and resume; no rewindSource for Live session controls (opens in a new tab)
Authentication
Server-side primary API key; temporary client API key and single-use Travel ticketSource for Authentication (opens in a new tab)

Authentication tokens are credentials, not billable language-model tokens.

Video duration
3-minute experience described in the product guideSource for Video duration (opens in a new tab)

The SDK ignores maxExperienceTimeSec for this mode. The guide describes the experience; this is not an independently verified universal API hard cap.

Instruction character limit
2,000Source for Instruction character limit (opens in a new tab)

Non-empty text instructions, measured in characters.

Usage metering
World creation + instruction calls where supported + generated experience secondsSource for Usage metering (opens in a new tab)

Regional original API prices; web credits and subscriptions have separate terms.

Data retention
Model Studio standard inference retention is up to 30 days, with legal/security exceptions; stateful files persist until deleted. HappyOyster is absent from the documented ZDR-supported model list. Do not treat a session ticket or artifact URL as a zero-retention guarantee.Source for Data retention (opens in a new tab)
Web product content-use policy
Web terms allow use of user content for model development and grant a broad content licenseSource for Web product content-use policy (opens in a new tab)

Separate from the Model Studio API deployment policy.

Web product retention
Purpose-based retention, including legal exceptions; no fixed general periodSource for Web product retention (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.

Not supported

Context caching is explicitly unsupported. Reusing a world or Travel recording does not establish discounted prompt caching.

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

Official terms reserve rights in the models, license service access and prohibit extraction of underlying parameters or weights. The reviewed releases are hosted model services without a documented public-weight license. Public SDKs and OpenAPI documentation do not release their weights.
