# Pricing and Billing

## Model **API Pricing**

Model usage is charged either on per GPU-second basis or per Generation basis. You can view a specific model pricing on it's pricing tab. (example: <https://www.segmind.com/models/gpt-image-1/pricing>)

**Per-GPU-second**

Segmind charges API requests based on **GPU processing time**, measured **per second**. Each request’s cost is calculated according to how much GPU compute power is consumed during model execution.

We host our models across a variety of **GPUs** (such as A100, H100, and L40S) and **cloud providers**, which means the **price can vary by model** depending on the underlying hardware and infrastructure used. Models running on higher-end GPUs typically incur higher per-second charges but deliver faster performance.

You can find detailed information on each model’s **pricing**, **GPU type**, and **expected generation speed** directly on its model page. For example: [CogVideo5b-image2video pricing](https://www.segmind.com/models/z-image-turbo/pricing)

This transparent, usage-based pricing ensures you only pay for the **exact compute resources** your requests consume, making it easy to scale your workloads efficiently across different models and hardware configurations.

**Per-generation**

For these models, credits are deducted on per generation basis. Please note that some parameters such as number of generated seconds for videos or resolution of the output can vary the pricing per generation. Please check the pricing page of a specific model to know the exact details.

You can track exactly how much you’ve been charged for each request on your account’s [usage page](https://cloud.segmind.com/console/usage). From this page, you can see how much you have left in your account (in dollars), the number of requests you’ve made today, and the total number of requests you’ve made from this account

## **Billing logic**

Segmind uses a **credit reservation** system to ensure fair billing. Here is how it works:

1. **Before execution**: When you send an API request, Segmind reserves an estimated amount of credits from your account balance based on the model and expected processing time.
2. **On success (HTTP 200)**: Credits are deducted based on the **actual GPU time** consumed during the request. Any over-reserved credits are returned to your balance.
3. **On failure (HTTP 4xx/5xx)**: Reserved credits are **fully rolled back** to your account. You are **not charged** for failed requests.

{% hint style="info" %}
**Key point:** If a request fails for any reason — whether due to invalid parameters, server errors, timeouts, or content moderation — your credits are returned in full. You only pay for requests that successfully produce an output.
{% endhint %}

If you notice a temporary dip in your balance during processing, this is the reservation in action. The balance corrects itself once the request completes or fails.

## **PixelFlow Pricing**

The charge for running Workflows created on PixelFlow will simply be the sum of the parts (the sum cost of running each model in the workflow).

### **PixelFlow Platform Subscription Pricing**

Detailed Pricing for the PixelFlow graphic user interface where you can create custom workflows can be found on the [pricing page](https://www.segmind.com/pricing). Users who subscribe to PixelFlow will be given credits equivalent to the amount they pay.

* Pro accounts will be credited $39/month.
* Business accounts will be credited $99/month.

## **Billing**

Every account, by default, starts as a “Free Account” on Flexible plan. Recharge with as low as $10 to get started.

From the [Billing Page](https://cloud.segmind.com/console/billing), you will find two methods of adding credits to your account.

1. Recharge. Simply use your credit card to add any dollar amount to your account.
2. Convert to Auto Recharge Billing. Enter in your credit card information and setup auto recharge to add credits once you balance falls below a selected number. Track your usage from your account’s [usage page](https://cloud.segmind.com/console/usage).
