Last updated: 2026-08-08

## Model

Mia21 uses a **prepaid credit wallet**. There is **no free tier**.

- **1 credit = $0.001 USD** (1,000 credits = $1.00 of usage value before fees)
- **Minimum first load: $5**
- Credits **never expire**
- Wallet UI is a **fuel gauge** (credits left), not a lifetime total that grows forever

## Managed usage (Mia keys)

- Model tokens billed at **provider cost + published provider tax** (Swiss VAT standard rate on managed provider usage, currently **8.1%**)
- **Token markup: 0%** — Mia does not mark up model tokens
- Margin comes from: memory, voice, BYOK platform fee, and top-up platform fee

## Top-ups

- Platform fee on every top-up: **~5.5%** (covers Stripe processing + margin)
- Credits granted ≈ `floor(paid_usd × (1 − fee) / 0.001)`
- Example: $5 load → **4,725 credits** after fee

## Bring your own keys (BYOK)

- Pay OpenAI / Anthropic / Google / etc. directly for tokens
- Mia charges a **platform fee per 1M tokens** for routing, memory orchestration, and analytics
- Same memory & voice APIs; still one Mia API key for your app
