Microsoft MAI voice models land on Vercel AI Gateway, callable through one API with no inference markup
Vercel and Microsoft AI (MAI) have partnered to bring MAI models to AI Gateway, making the platform one of a limited number of places that offer access to MAI models. Three audio models are supported: MAI-Voice-2.1 generates expressive speech in 23 languages and keeps a consistent speaker across longer passages, MAI-Voice-2.1-Flash targets lower-latency interactions, and MAI-Transcribe-2 Streaming returns partial transcripts as audio arrives. AI Gateway bills these models at their listed rates, with no platform fee or markup on inference.
