Between $0.06 and $0.13 per minute all-in. The $0.05 platform fee is fixed; the rest is provider usage passed through at cost plus telephony. A budget cascade (Deepgram, gpt-4o-mini, Cartesia) runs about $0.10 per minute on our keys and $0.06 on yours.
The runtime itself: every pipeline mode, web and phone calls, call recording, transcripts, and post-call processing. It is billed per second, not rounded up to whole minutes.
Provider lines drop to $0. You are billed by OpenAI, Deepgram, ElevenLabs, or whoever you use directly, and we add no markup on top. All that remains from us is the $0.05 platform fee and any telephony you buy through us.
