# Fish Audio models now available on Vercel AI Gateway for free By Steven Van · 2026-08-19 Fish Audio's audio models are now available on AI Gateway. Vercel's [AI Gateway]() now offers [four Fish Audio models](), and every one is free through September 18 to mark the launch. - **fish-audio/s2.1-pro**: text-to-speech built for low-latency streaming, clones a voice from a reference recording. - **fish-audio/transcribe-1**: transcription that returns text plus timestamped segments down to individual words. - **fish-audio/s2-pro**: text-to-speech covering around eighty languages, with inline tags to change how a single word or phrase is delivered. - **fish-audio/s1**: text-to-speech that reads text carrying markers for emotion, tone, and sound effects. Text-to-speech normally costs $15.00 per million characters and speech-to-text $0.36 per hour of audio; both are free until the offer ends. Using a model's standard name, such as fish-audio/s2.1-pro, will start billing automatically once the period closes; adding a -free suffix instead makes the model stop serving at that point rather than bill. Speech and transcription work with the current AI SDK 7 release, through generateSpeech and transcribe, and the models can also be tried without code in the Playground.
