About Vapi
Vapi widens its transcriber menu as Soniox hits GA and Deepgram Flux goes multilingual
Vapi is a platform for building voice AI agents. The substantive recent shipping is concentrated in its speech-to-text layer: the Soniox transcriber reached general availability for all customers, and Deepgram's Flux model gained multilingual support — both configurable per assistant. Most other weekly changelog entries in this window are empty placeholders with no described changes.
