# Speech-to-text pricing

> 47 STT model(s) from 7 provider(s), cheapest first.

47 STT model(s) from 7 provider(s). Priced from `input_audio_kseconds`, US dollars per 1,000 seconds of input audio. Shown per minute, the unit vendors quote. Pick a vendor in the sidebar to see that vendor alone.

Streaming and batch ship as separate rows, as do language tiers, because vendors price them separately.
