Billed per second, so a 90-second call costs ninety seconds — not two minutes. Nothing here is a plan; there is nothing to outgrow.

of every minute goes to Talkif rather than to a vendor. Here is what it is.

The transcriber, the language model and the voice are metered by their vendors and passed through untouched. What you pay us for is everything that has to be running for those three to work at all — noise cancellation on the inbound audio, voice-activity detection deciding when you have actually stopped speaking, a turn model judging whether a pause means thinking or your go. None of them are sold by the minute. All of them run from connect to hang-up, on a container kept warm for that one call.

Our margin is in there too. We would rather it sat on the invoice as a line you can argue with than vanish into a per-minute rate you cannot.

Every rate

Pick a different stack, pay a different rate.

The estimate above opens on the cheapest live model for each part, over SIP; you are not held to it. Each group below is the spread you are choosing within — open one for the full list. Every figure is read from the same pricing API the platform bills against, on each page load.

What the agent thinks with. Cheaper models answer scripted, well-bounded calls perfectly well; you pay up for reasoning the hard ones need.

What it hears. The spread here is mostly accents, background noise and how fast a word is recognised — on a clean line the cheapest is hard to fault.
