No model-specific prompt-cache contract verified. Server-side audio segmentation, speech buffers and reused decoders do not establish discounted token caching.
No public immutable checkpoint selector or standalone API contract verified for this dated/internal system.
Access
Internal shipped model line documented in the September paper. Exact private artifact, current selector, access and price require provider confirmation.

Data & enterprise terms
The paper releases no model weights, data or internal tooling. No standalone processing agreement or data-retention contract is established for this paper-only/datetime-specific record; current preview policies are not backfilled.
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
Large production model · FLEURS Greek
KIEFER SA / Sophea authors · provider-reported
9.13% WER
Table 2 large production model column. Not Table 3’s separate Whisper ensemble member or an all-Greek accuracy 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
The provider-authored production paper identifies internal adapted speech models and combined systems and explicitly releases none of their weights, data or tooling. This record covers the specified proprietary adaptation/system; the original Qwen, Whisper and Canary base weights and stock-weight Turbo are not reclassified as closed.
