Rate conditions
Converted from $0.03/1,000 characters. Character billing, not tokens or a fixed audio-minute rate. Starter concurrency 20; enterprise terms negotiated. Free allowance is inconsistent across the page (about 800 minutes vs 3,000), so no exact free quota is assumed.
Rime documents character-count-only collection by default and no customer-content model training without opt-in. Optional request retention is disabled by default and can be enabled for support/quality investigation; enabling it does not authorize training. Voice-clone recordings have separate customer-specific training permission. MSA/BAA terms may vary.
Parameters are fixed at connection creation. segment=bySentence/never/immediate controls when buffered text is synthesized; explicit flush is available. Inline per-word speed is not read by WebSocket endpoints.Source for Generation controls (opens in a new tab)
The per-word restriction is established in the speed guide, even though legacy parameter lists still show inlineSpeedAlpha.

Single engine serves HTTP POST / or /invocations, gRPC and WebSocket. Protocol envelopes differ from cloud ws3; all share one capacity pool.Source for Request mode (opens in a new tab)
Image language coverage can differ from cloud; confirm the selected image.
Endpoint pricing has not been collected. Check the provider for applicable rates.
Data & enterprise terms
Runtime license checked locally; aggregate usage counts sent over HTTPS to Rime. Synthesis text and audio remain in the deployment. A metering outage does not stop synthesis; in-memory reports retry and older pending windows can be dropped.
Exact image from official deployment config, not a guarantee of the latest cloud checkpoint.
Access
Licensed private single-container deployment in the customer’s Baseten workspace. The repository currently pins an older image than the on-prem quickstart; confirm image/license compatibility.
Regions
Region selected in the customer’s Baseten workspace.
Endpoint pricing has not been collected. Check the provider for applicable rates.
Data & enterprise terms
Rime license and metering credentials are supplied as secrets; callers authenticate to Baseten. Complete host retention and operational terms require the deployment contract.
LiveKit documents no inference-content retention by default, including underlying providers, with optional observability and voice storage handled separately.
Dedicated deployment offered by Together’s model card. Provision GPU capacity; not a current serverless listing. Pricing includes both character usage and GPU time.
Regions
Dedicated deployment region and capacity depend on the provisioned endpoint.

Rate conditions
This $10/1M-character component excludes required GPU hourly charges, whose amount depends on hardware and provisioning. It is not an all-inclusive serverless rate. Native Rime cloud retirement does not automatically retire this dedicated deployment.
General Together policy stores prompts/responses by default with an organization ZDR setting; training sharing is separately opt-in. The dedicated Arcana launch advertises ZDR, so confirm the actual dedicated endpoint contract and logging configuration rather than applying a blanket assumption.
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.

Voice choices

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
Rime reserves ownership of its AI voice models and grants a limited service license. Current Coda/Mist deployments explicitly use private, closed-source licensed engine images; Together describes Arcana as proprietary. The separately released Rimecaster speaker-embedding model is CC-BY-4.0 and is excluded.
