Use standard model names if automatic billing after the offer is acceptable, or append -free to make requests stop when it ends. The free period is temporary. The material gives capability descriptions but no comparative quality, latency, or reliability measurements for choosing among the models.
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.
