# How pricing works

> Elaris billing has two layers — a subscription plan (Free / Basic ~$49 / Pro ~$399 / Enterprise) and usage credits priced at ~$0.008 each for every image, video, audio, and VTON generation.

Elaris billing is two-layered: a **subscription plan** that controls seat access and feature entitlements, plus **usage credits** that meter every AI generation.

## What are the two billing layers?

| Layer                 | What it covers                                                                             |
| --------------------- | ------------------------------------------------------------------------------------------ |
| **Subscription plan** | Seat access, plan-included credits, feature entitlements (Free / Basic / Pro / Enterprise) |
| **Credits**           | Per-generation usage across Studio, Campaigns, URL to Video, VTON, and MCP                 |

You need both: a plan for access, and a credit balance to generate.

## How is the credit amount calculated?

<CodeGroup>
  ```text Credit formula theme={"dark"}
  1 credit ≈ $0.008 model cost
  credits  = ceil(usd / 0.008)   # minimum 1 credit per generation
  ```
</CodeGroup>

This anchor is consistent across all media types. The same formula converts underlying model cost to credits whether you're generating a single image or a 12-second video clip.

## How are different media types priced?

<Tabs>
  <Tab title="Images">
    Image costs vary by model family and generation method:

    * **Per-image** — flat cost per output (e.g. Flux 2 Flash = 1 credit, Flux 2 Max = 8 credits)
    * **Per-megapixel** — cost scales with output resolution
    * **Token / quality tiers** — used by models like GPT Image (21 credits base; quality tiers may add more)

    Higher resolution outputs (2K, 4K) apply a resolution multiplier on top of the base model cost.

    See [Image models](/docs/models/image) for the full per-model credit table.
  </Tab>

  <Tab title="Video">
    Video is priced primarily **per second of output**, with multipliers for:

    * **Duration** — longer clips cost more proportionally
    * **Resolution / tier** — premium models carry a higher per-second rate
    * **Audio** — models with built-in audio (e.g. Veo 3.1) may include an audio multiplier

    Studio shows the estimated credit cost before you confirm. MCP video tools accept `durationSeconds` (commonly 2–12 seconds).

    See [Video models](/docs/models/video) for per-family pricing guidance.
  </Tab>

  <Tab title="Audio & VTON">
    * **Text-to-speech (TTS)** — fixed-ish action cost per generation (varies by model and character count)
    * **Dialogue** — higher credit cost than single-voice TTS
    * **Virtual Try-On (VTON)** — metered **per second** of session time

    See [Audio models](/docs/models/audio) for TTS model options and relative costs.
  </Tab>
</Tabs>

## How are campaign batches billed?

Large campaign wizard flows use **flow-level deductions** rather than dozens of tiny per-asset charges. You see one predictable deduction per wizard phase, not incremental charges mid-flow.

| Campaign flow            | Typical deduction |
| ------------------------ | ----------------- |
| Full AI generation batch | 60 credits        |
| Moodboard generation     | 50 credits        |

<Tip>
  Studio always shows a cost estimate before you commit to a generation. For campaigns, the total deduction appears at the wizard confirmation step — review it before proceeding.
