Exact SDK model selector. Current Compose OpenAPI omits the model property even though the SDK sends it; backend acceptance and family mapping are not independently exercised.
Access
POST https://api.simli.ai/compose/token with x-simli-api-key and a compatible faceId, then use the SDK with P2P or LiveKit WebRTC transport. Account and face availability apply.
Regions
No model-specific processing-region guarantee established. Provider is based in Norway; its privacy policy lists international service providers, which does not establish Norway-only inference.
audio
SDK streaming input: PCM16 audio at 16 kHz. The general audio guide demonstrates mono conversion; compressed-file support on the static route is separate.Source for audio (opens in a new tab)
sessionDefaults
maxSessionLength defaults to 3,600 seconds and maxIdleTime to 300 seconds. These are configurable defaults; a hard maximum is not published in the schema.Source for sessionDefaults (opens in a new tab)
transports
P2P and LiveKit WebRTC. Current AsyncAPI names /compose/webrtc/peer_to_peer and /compose/webrtc/livekit. The migration guide uses an older p2p shorthand; prefer the current SDK.Source for transports (opens in a new tab)
connectionDeadline
P2P offer must arrive within 30 seconds; LiveKit join must complete within 30 seconds. These are connection deadlines, not inference latency guarantees.Source for connectionDeadline (opens in a new tab)
handleSilence defaults to true. The JavaScript guide recommends false when using listenToMediastreamTrack to avoid artifacts.Source for silence (opens in a new tab)
Standard published terms and privacy policy permit training and service-development use of user content and activity data. No enterprise opt-out or inference-specific deletion guarantee established here.Source for Training data policy (opens in a new tab)
monitoring
GET /history/sessions supports Unix start/end-time filters. GET /ratelimiter/sessions reports active sessions. These are account APIs, not additional models.Source for monitoring (opens in a new tab)
selectorContract
SDK type exposes model=fasttalk or artalk and serializes it in the token request. Current REST Compose schema omits this field; treat the discrepancy as unresolved, not a verified immutable serving checkpoint.Source for selectorContract (opens in a new tab)
Pricing terms
Public rates are split by Trinity versus Legacy faces. No reliable mapping from this selector to one pricing family is established, so no selector-specific numeric tariff is assigned.Source for Pricing terms (opens in a new tab)
Endpoint pricing has not been collected. Check the provider for applicable rates.
Data & enterprise terms
Published privacy policy permits use of content and activity data for training/research. User content is retained as necessary; account data is deleted on request or within 12 months after account termination, while name/email have a separate 24-month period. Legal exceptions and connected providers apply; no default zero-retention promise.
Explicit SimliModels enum in ConfigurableSessionRequest; route is deprecated.
Access
Deprecated POST https://api.simli.ai/auto/start/configurable supports a model selector and external TTS/LLM configuration. Simli Auto development has ceased according to the migration guide; current SDK rendering is a separate integration path.
Regions
No model-specific processing-region guarantee established. Provider is based in Norway; its privacy policy lists international service providers, which does not establish Norway-only inference.
Endpoint availability
Route marked deprecated; migration guide says Auto development has ceased for now. Do not infer that the selector itself has been retired from all SDK rendering.Source for Endpoint availability (opens in a new tab)
externalModels
Configurable external speech and LLM stack. Current schema defaults to Cartesia sonic-turbo-2025-03-07 and OpenAI gpt-4o-mini, with ARTalk as the rendering default. These are external providers, not Simli foundation models.Source for externalModels (opens in a new tab)

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
An explicitly documented version family or callable service selector. Underlying checkpoint identity is undisclosed, so this is cataloged as a managed component rather than a claim of independently identified native weights.
