How it works

Pricing is pay-as-you-go by the audio hour in euros: the Solaria-3 model costs €0.16 an hour and Solaria-1 costs €0.27 an hour for async transcription, with real-time at €0.68 an hour. A one-time €50 credit, valid for a year, lets you test the API before paying.

Gladia is a good fit for developers building multilingual voice products, live captioning, or meeting analysis tools. The combination of transcription, translation, and real-time speed in one API is its main advantage. For a simple transcript, a cheaper batch API will do, but for live, multilingual audio, Gladia is a strong choice.
