Millis AI plans & pricing
| Plan | Monthly | Annual | Billing | Notes | Source |
|---|---|---|---|---|---|
| Pay as you go STALE · 2026-09-10 | $0 | — | Per minute | Millis publishes exactly one platform rate: 'We charge a base rate of $0.02 per minute for using the Millis AI platform.' There is no monthly subscription tier and no published included-minute bundle, so the monthly price is 0 and included minutes are not recorded. That $0.02 is orchestration ONLY — STT, LLM and TTS bill separately on top. STT: $0.0043/min. LLM, per minute: GPT-3.5 Turbo ~$0.0004, Meta Llama-3 ~$0.00018, GPT-4o ~$0.004, GPT-4 Turbo ~$0.008, and no charge for a custom LLM endpoint. TTS is priced PER 1,000 CHARACTERS, not per minute: Neets $0.001, OpenAI $0.015, Deepgram $0.015, Cartesia $0.0392, Rime $0.075, ElevenLabs $0.10, PlayHT $0.25. Because TTS is character-metered, all-in cost depends on how much the agent actually speaks, and voice choice is the dominant variable. No free-tier allowance, trial length or concurrency limit is published. | docs.millis.ai |
Last verified 2026-09-10. STALE marks a plan we have not re-checked at its source in over 30 days. Every plan above is marked — we flag rather than silently retain. Re-verified against docs.millis.ai/pricing on 2026-09-10, which is Millis' only pricing page. The $0.02/min base rate and the STT and LLM per-minute rates are confirmed verbatim. ONE MATERIAL CORRECTION: an earlier version of this record stated TTS as '$0.0005/min to $0.125/min'. The page publishes TTS per 1,000 CHARACTERS, not per minute — ElevenLabs $0.10, PlayHT $0.25, Rime $0.075, Cartesia $0.0392, OpenAI $0.015, Deepgram $0.015, Neets $0.001 per 1,000 characters. That per-minute range was an unpublished conversion and has been replaced with the published units. Three key features claims that an earlier version of this record carried (a 600ms latency figure, no-code/low-code builders, and phone numbers in 100+ countries) do not appear on this page and were removed rather than sourced to marketing copy. Millis publishes no monthly tier, no free-tier allowance and no concurrency limit, so one pay-as-you-go plan is listed rather than an invented ladder.

Capabilities
Integrations: OpenAI, Meta Llama, ElevenLabs, Deepgram, Rime, Twilio, Webhooks, Custom LLM endpoints.
Key features: Lowest published orchestration rate in this set at $0.02/min, with the model and voice layers fully unbundled so buyers optimise each independently; Custom LLM endpoints carry no Millis surcharge, making a self-hosted model genuinely free at the model layer; Seven TTS vendors and five-plus LLM options priced individually, so the stack can be tuned rather than accepted; STT at a flat $0.0043/min is among the cheapest transcription lines published in this category.
Plan limits: The $0.02/min headline is orchestration only; STT, LLM and TTS are three further meters on top; TTS is billed per 1,000 characters rather than per minute, and the spread is 250x between the cheapest and dearest voice vendor ($0.001 to $0.25 per 1,000 characters), so voice choice dominates the real bill and is hard to forecast from a per-minute budget; No monthly plans, no published concurrency limits, and no published free-tier or trial allowance; No HIPAA, SOC 2 or GDPR statement published anywhere, so none of the three is recorded; Pricing lives only in developer docs, not on a commercial pricing page, so terms can change without a versioned announcement.

This standing as a plaque
Millis AI currently holds a gold deskmark here — Rank 2 of 13 · AI Voice Agents. Anyone may show it. There is nothing to apply for, nothing to pay, and displaying it changes no score: the standing comes from the published algorithm, which never reads commission data. We never ask anyone to show it, and its link carries rel="nofollow".
The image is drawn from our live data, so it follows the standing rather than freezing it: if Millis AI moves up or down a tier, the plaque on your own site says so at our next publish. Nothing is tracked beyond the ordinary web-server log that records any image request.
