Every claim on this page is refundable if it is untrue — refund policy.
Building it yourself: ~2h of agent time across about 4 attempts. Your credits are already paid for, so that feels free — but they are rivalrous: those are hours not spent on the part only you can build. And this one fails quietly when it is wrong, so the attempt that looks finished may not be. $14.70.
Swap speech-to-text, the model, and text-to-speech independently — or use a bundled realtime session — behind one interface, with a pricing catalog and a cost estimator for your own session shape. Includes the finding nobody publishes: on a balanced session the voice costs more than the intelligence.
The table nobody publishes
A 10-minute session, 20 turns:
| Arrangement | Cost | Latency | | |---|---|---|---| | Free / keyless | **$0.0000** | ~1050ms | no key, on-device | | Fully on-device | **$0.0000** | ~1050ms | audio never leaves the machine | | Cheapest hosted | **$0.1278** | ~480ms | | | Balanced | **$0.2167** | ~960ms | | | Fastest (realtime) | **$3.0000** | ~320ms | |
**Realtime costs 23× the cheapest hosted pipeline** — and it is the default arrangement in most voice-assistant code. Sometimes that latency is worth paying for. It should be a decision, not a default you inherited.
The counterintuitive finding
**The voice can cost more than the intelligence.** On a balanced 20-turn session, TTS runs $0.12 and the model runs $0.09. Everyone assumes the LLM is the expensive part, so nobody scrutinizes the TTS choice — and the premium voice option is roughly 12× the alternatives. Hearing, meanwhile, is nearly free.
What you get
- One interface over STT, LLM, TTS, and bundled realtime providers.
- A pricing catalog with per-stage cost, typical latency, keyless/on-device flags, and an honest caveat on every "free" or "best" option — browser speech quality varies by browser, small local models can't tool-call reliably, premium voices are priced like it.
- `estimateCost(stack, session)` for **your** session shape, `recommendStack(preference)` across six preferences, and `compareStacks()` which generates the table above.
Honest about the numbers
Every catalog entry carries `asOf` and its pricing source. List prices move; these are estimates for comparison and the code never presents them as a bill.
Proof
17 tests, including guards that the estimator throws on an unknown provider rather than silently costing zero, and refuses a provider used in the wrong stage.
