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
arcanav2
Access
Native cloud retirement on August 15, 2026. This selector now serves Coda; it does not select the original Arcana weights.
Regions
US West (us-west-2) and US East (us-east-1) native regions. These routing details are not a blanket contractual residency guarantee.

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

Data & enterprise terms

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.

API model ID
Not collected

A version-pinned deployment selector is not established.

Access
Existing Arcana images remain pullable but receive no updates or support, including security patches. Exact image/license availability depends on the existing customer agreement.
Regions
Customer-controlled deployment.
Endpoint retirement date
2026-08-15Source for Endpoint retirement date (opens in a new tab)

End of Rime updates/support for legacy on-prem Arcana, not loss of all ability to run an already licensed image.

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

Data & enterprise terms

Legacy licensed image behavior and telemetry must be checked against the specific deployment. The current standalone Coda/Mist policy is not applied retroactively.

Access
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

  1. 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.
Pricing source (opens in a new tab)

Data & enterprise terms

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

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

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.
