# Millis AI pricing (2026): plans, cost, and compliance

**Entry price:** $0 (free)/mo (Pay as you go). Among the 13 ai voice agents we track it is the cheapest; median entry $0/mo.
**Domain:** millis.ai
**Free tier:** Not published
**Compliance:** HIPAA Not published · SOC 2 Not published · GDPR Not published
**Integrations:** OpenAI, Meta Llama, ElevenLabs, Deepgram, Rime, Twilio, Webhooks, Custom LLM endpoints
**Best for:** Cost-sensitive developers who already run their own LLM and want to pay only for orchestration; Teams comfortable assembling and tuning their own STT/TTS/LLM stack and metering each piece; Rapid prototyping where cheap unbundled minutes beat enterprise assurances

## Plans

| Plan | Monthly | Annual | Billing | Notes | Source |
| --- | --- | --- | --- | --- | --- |
| Pay as you go | $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 monthlyUsd is 0 and minutesIncluded is null. 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 |

## Price changes

No change record has cleared two sources yet, so nothing is published on the wire.

**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 all three are null; Pricing lives only in developer docs, not on a commercial pricing page, so terms can change without a versioned announcement.

Provenance: 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: the draft 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. The draft's per-minute range was an unpublished conversion and has been replaced with the published units. Three keyFeatures claims the draft 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.
