# Understand pricing

> Use this guide to understand CometAPI billing units, pricing pages, and account-level pricing notes before calling models.

CometAPI adheres to a **transparent, fair** pricing system, divided into the following two situations:

***

## **1. Models with unified official pricing**

* **Billing Method**: Billed by **Token**.

* **Applicable Models**: Such as OpenAI, Claude series models, etc.

* **Billing Rules**:
  * The consumer price follows an official billing ratio of **0.8:1** compared to the official price, offering users a \*\*20% discount \*\*.

* **Volume Discounts**:
  * For monthly consumption exceeding **3000 USD**, or for enterprise users, please contact customer service for **lower discounts**.

***

## **2. Models without official APIs**

* **Billing Method**: Billed by **number of calls**.
* **Applicable Models**: Such as MidJourney, Kling, Luma, and other models without official APIs.
* **Billing Rules**:
  * cometAPI implements APIs for these models through technical means, charging per call, with pricing determined by cometAPI.
  * When using these services, prices also enjoy a **20% discount**.
