Audio sample rates

latency
Approximately 120 msSource for latency (opens in a new tab)

Provider-reported processing latency, not end-to-end network latency or a guaranteed SLA.

Audio formats
Interleaved float32 PCM through the Python SDKSource for Audio formats (opens in a new tab)
Audio direction
Desktop inventory includes independently trained inbound and outbound variantsSource for Audio direction (opens in a new tab)

A single SE2.1 version label groups those variants; public SDK-to-direction checkpoint mapping is not disclosed.

Access & pricing

Prices belong to an endpoint and billing tier. A provider listing does not guarantee access for every account or region.

Sanas enterprise application

Provider source (opens in a new tab)
API model ID
Not collected

A desktop model version or family name is not an exact public inference selector.

Access
Licensed Sanas desktop application; account/group administrators select the model and required feature entitlement.
Regions
Customer device or enterprise-configured remote inference; verify the selected account deployment

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

Data & enterprise terms

Deployment and diagnostic configuration affect data handling. Provider privacy policy covers account/usage information and voluntarily supplied audio samples; do not infer that every desktop feature processes locally or that all personal data is discarded.

Sanas Cloud · Python SDK

Provider source (opens in a new tab)
API model ID
SE2.1

SDK model key, not a REST language-model identifier.

Access
Create and activate an SDK instance, choose AudioAttributes.model_name, wait for RUNNING, then process interleaved float32 PCM frames at realtime speed.
Regions
Sanas Cloud: AWS Ohio us-east-2 and Mumbai ap-south-1; select region through account/project configuration
Audio formats
Interleaved float32 PCM framesSource for Audio formats (opens in a new tab)
Streaming audio chunks
Example feeds 20 ms frames every 20 ms; source must be paced in real timeSource for Streaming audio chunks (opens in a new tab)

An integration contract/example, not a maximum audio or context duration.

Request quotas
Not collected

No hard per-account concurrency or request cap verified. Marketing claims of hundreds of streams are not an entitlement.

Billing basis
Prepaid wallet; metered minutes deducted in real timeSource for Billing basis (opens in a new tab)
Included free allowance
$10 introductory credit, with expiry shown in the account walletSource for Included free allowance (opens in a new tab)

Promotional allowance, not a zero-dollar ongoing model rate.

Audio sample rates
16 kHz input and returned cloud audio; native model output is 8 kHz and is upsampledSource for Audio sample rates (opens in a new tab)

Rate conditions

  1. Published Sanas Cloud developer rate, metered from a prepaid wallet. Volume discounts by agreement. Desktop subscriptions, self-hosting and partner contracts are separate. Rounding and simultaneous-direction billing are not specified here.

Data & enterprise terms

Developer documentation says live call audio is processed without cloud audio storage. Account, usage and other personal data have contract-based retention: six-month post-termination deletion and up to one year for backups, with 30 days to request return/deletion. This is not a promise that all metadata is discarded. Consented samples and diagnostics require separate review.

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

Sanas documents these as its trained speech models and supplies them through licensed applications and hosted SDK inference. Its terms reserve the software/content rights and prohibit reverse engineering and redistribution. No open-weight release is established by these primary model and access documents.
