## Why Included

Vercel AI Gateway added four Fish Audio models for speech generation and transcription, with AI SDK 7 support and a free window whose model naming determines later billing.

## Source Summary

AI Gateway added **four Fish Audio models** for text-to-speech and transcription. Regular prices are **$15 per million characters** and **$0.36 per audio hour**, but both are free through September 18.

## Practical Implication

Builders can call speech and transcription through **AI SDK 7**. Use standard model names if automatic billing after the offer is acceptable, or append -free to make requests stop when it ends.

## Agent-Ready Context

The free period is temporary. The material gives capability descriptions but no comparative quality, latency, or reliability measurements for choosing among the models.

## Connected Context

Feed7 judgment across 542 accumulated Signals:

This extends the shared AI SDK and Gateway surface from visual generation into both speech output and transcription, enabling audio pipelines without a separate provider integration. The temporary free routes are useful for bounded evaluation, and the -free suffix uniquely prevents accidental paid continuation; absent comparative measurements, the release establishes access and billing behavior rather than a preferred audio model.

- [AI Gateway now supports streaming transcription](https://feed7.dev/p/ai-gateway-now-supports-streaming-transcription-1sq8mn3) — Streaming transcription supplies the lower-latency input path that can operationalize Fish Audio’s transcription models; model availability and the streaming transport are complementary prerequisites for live voice-input workflows.
- [Grok Voice Think Fast 2.0 now available on AI Gateway](https://feed7.dev/p/grok-voice-think-fast-2-0-now-available-on-ai-gateway-1dacr27) — Grok provides an integrated realtime speech-to-speech agent route, whereas Fish Audio exposes separate synthesis and transcription components; choosing between them changes orchestration, latency testing, and credential requirements.
- [Gemini 3.7 Flash now available on AI Gateway for 50% off](https://feed7.dev/p/gemini-3-7-flash-now-available-on-ai-gateway-for-50-off-040tuet) — Both use temporary Gateway pricing to lower evaluation cost, but Fish Audio’s -free model names can fail closed when the offer ends, avoiding the automatic transition to paid billing that promotion-based routes otherwise require teams to reassess.
