Is my audio data used to train Gladia's models?

By default on Growth and Enterprise plans, there is an option for automatic model training opt-out. On Enterprise plans, it is the default. This is contractually guaranteed in the DPA.

What is the difference between Async and Real-time STT?

Async STT is for pre-recorded files and offers the highest accuracy. Real-time STT provides sub-300ms latency for live streaming audio from microphones or calls.

Can I bring my own LLM to the Audio Intelligence pipeline?

Yes, Gladia's Audio-to-LLM pipeline supports both integrated LLM options and a 'Bring Your Own Model' (BYOM) approach for custom processing.

Do you offer volume discounts?

Yes, volume discounts are available, primarily through the Enterprise plan. Contact our sales team for custom pricing based on your audio volume.

What are the concurrency limits?

Limits vary by plan. Starter has 30 real-time and 25 async concurrent requests. Growth offers flexible limits, and Enterprise provides unlimited concurrent requests.

How does Gladia compare to self-hosting Whisper?

Teams moving from self-hosted Whisper to Gladia report ~20% less DevOps effort. Gladia provides managed scaling, SLAs, and a broader feature set like real-time streaming and Audio Intelligence without infrastructure overhead.
