Model controls
Not collected

The SDK realtime inputSchema is empty because session configuration is handled outside this model table. It does not prove the model accepts no inputs.

Reference guidance
Not collected

Exact prompt, reference-image, duration and file-size constraints remain unverified for this historical revision.

Pricing coverage
Not collected

No verified historical tariff. Current Lucy, avatar or lip-sync prices must not be substituted.

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

Data & enterprise terms

Retention, training use, regional processing and enterprise terms have not been summarized for this endpoint.

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

Provider SDK names this distinct hosted model and the changelog announces its retirement. No matching weights appear in the reviewed official inventories; closed-weight classification is inferred from that evidence and provider API terms, not from the open SDK license.
