Rate conditions
Published self-service hourly audio rate, credit-based billing; taxes and negotiated enterprise terms are separate. Optional feature surcharges, where applicable, require the provider’s current account conditions. No text-token rate or cost per question is inferred.
Terms: standard API content and outputs are not retained unless storage is enabled or required by the feature; stored content defaults to 35 days, with separately retained usage metadata and temporary residual backup/log copies. Self-service accounts are automatically enrolled in model improvement. FAQ narrows training to audio marked for storage; enterprise participation and opt-out depend on the agreement. Accent documents a per-request training_permitted=false opt-out. Do not infer a universal no-training or immediate-deletion guarantee.
Endpoint path selects the served family; not a request model parameter or immutable checkpoint ID.
Access
Connect to wss://platform.modulate.ai/api/velma-2-pii-phi-redaction-streaming with api_key in the WebSocket query. Send the endpoint-specific audio/config frames and finish with its documented end-of-stream signal.
Regions
Public endpoint deployment region and regional routing are not specified in the reviewed API contract.

A binary frame follows an utterance only when redacted_audio is non-null. The done event can also be followed by trailing audio when trailing_redacted_audio is non-null. Do not parse the entire stream as JSON.

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
Modulate presents these as its Velma model suite and audio-native proprietary technology. Its terms retain rights in algorithms and models and license hosted inference, with no public weight artifact identified. Entries represent the named closed managed model families, including ensembles, not invented individual internal checkpoints.
