Historical proprietary ASR system combining a modified Whisper core with additional models and domain adaptation. The public Whisper weights are not reclassified as closed.
Historical article describes multilingual support but no complete release-specific language inventory was verified. Current Solaria lists 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
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
Gladia explicitly calls Whisper-Zero its first proprietary ASR system. The launch article describes a reworked Whisper core combined with multiple additional models and provider fine-tuning. This record covers that closed composite service, not the original open-weight OpenAI Whisper release.
