Legacy route scheduled to retire October 24, 2026 at 00:00 UTC. The changelog says it remains available until that cutoff. Current host-specific prices and non-default service tiers have not been collected. Use a Perplexity API key and POST /v1/agent.
audio_to_llm_config.model selects the external LLM after transcription.
Access
Enable audio_to_llm and provide prompts on a prerecorded Gladia job. Each prompt is run on the resulting transcript text. Raw audio and other response fields are not supplied to the LLM. Availability and access depend on the account.
Regions
External OpenRouter/provider routing; ASR cluster residency does not establish LLM residency
Endpoint pricing has not been collected. Check the provider for applicable rates.
Data & enterprise terms
Paid defaults: audio and transcripts 3 weeks, API metadata 1 year, logs an unspecified limited period. Free defaults retain all four data types for 1 year. Enterprise custom retention value 0 means deletion within 24 hours; separate ZDR means ephemeral processing and no later retrieval. ZDR disables file upload and polling: supply an external audio URL and receive callbacks. The compliance hub says no training without explicit agreement; a pricing blog says Starter training may be enabled by default, so confirm the applicable account agreement. External LLM/OpenRouter routing may use additional subprocessors and regions; Gladia ASR residency must not be treated as an end-to-end guarantee for this route.
Exact rendered-prefix matching. No sharing across organizations or processing regions. Routing and load can prevent hits. Check account retention policy before selecting persistent caching.Source for Limits & data boundaries (opens in a new tab)
Standard text-token rates. Other modalities, tool usage and processing modes are billed separately.

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.

Why it is included
Proprietary OpenAI release in the official hosted-model catalog. Explicit open-weight releases and unresolved routing aliases are excluded.
