Native model options
krisp-nc-o-pro-v1Source for Native model options (opens in a new tab)

Published SDK model name or model filename, not a hosted LLM model selector.

Audio sample rates
32 kHzSource for Audio sample rates (opens in a new tab)

Model working sample rate. SDK resamples streams to and from this rate; it is not a token limit.

Published model size
5.8 MBSource for Published model size (opens in a new tab)

Published model file size, not RAM requirement or parameter count.

Model aliases
c8.f.s.026300Source for Model aliases (opens in a new tab)

Legacy filename stem for this model.

Input requirements
Raw microphone/uplink stream with one primary speaker. Do not substitute for a codec-degraded multi-speaker downlink model.Source for Input requirements (opens in a new tab)

Access & pricing

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

API model ID
krisp-nc-o-pro-v1

SDK model identifier; exact artifact availability depends on the supplied SDK bundle.

Access
Request commercial SDK access; load the licensed model artifact and process audio frames on your infrastructure.
Regions
Customer-managed device or server deployment
Deployment mode
Licensed local inference; customer device/serverSource for Deployment mode (opens in a new tab)
Billing basis
Commercial SDK pricing by agreement; public developer tiers list no numeric model-level priceSource for Billing basis (opens in a new tab)

Meeting Assistant seat prices do not establish a developer inference tariff.

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

Data & enterprise terms

SDK processing stays on the customer’s machines. The SDK security guide says Krisp does not collect audio or derived metadata and network access is for licensing. Optional metadata is generated locally. This policy does not describe the cloud Voice Translation API or meeting-recording service.

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

Krisp identifies its AI models as proprietary, licenses the software and restricts extraction, modification and redistribution. The commercial SDK distributes licensed .kef inference artifacts through its customer portal, not open-source model releases. Historical/current generations are included only where named in provider sources.
