# Credits

> Credits are the universal currency of the Profy platform

Credits are the **universal currency** of the Profy platform. Whether you're chatting with an Expert, generating images, or executing code — all AI calls are metered in credits.

## Where Credits Come From

You can obtain credits through the following channels:

## How Credits Are Spent

Every AI call consumes credits. The amount depends on the **model used** and the **billing unit**:

### Billing Units

| Billing Unit      | Calculation                                           | Use Case                                   |
| ----------------- | ----------------------------------------------------- | ------------------------------------------ |
| **Per Token**     | Based on the number of input and output tokens        | Text conversations (most scenarios)        |
| **Per Call**      | Fixed cost per call                                   | Image generation, music generation         |
| **Per Character** | Based on the number of input text characters          | Text-to-speech (TTS)                       |
| **Per Duration**  | Based on the duration of generated content in seconds | Video generation, speech recognition (ASR) |

<Tip>
  Different AI models have different rates. Generally, more powerful models consume more credits. You can switch models in conversation settings to control credit consumption.
</Tip>

### Consumption Examples

The following are intuitive references — actual consumption is shown in the product in real time:

* **A typical text conversation**: Tens to hundreds of credits (depending on conversation length and model choice)
* **Generating an image**: Hundreds to thousands of credits (depending on the selected image model)
* **Generating a video**: Billed by video duration
* **Text-to-speech**: Billed by text character count

## Credit Consumption Priority

When you have credits from multiple sources, the platform consumes them in a specific priority order. The core rule is: **consume expiring credits first, then non-expiring ones**.

<AccordionGroup>
  <Accordion title="Consumption Priority Details">
    The platform divides your credits into multiple buckets, consumed in this order:

    1. Daily bonus credits (consumed first)
    2. Signup bonus credits
    3. Plan bonus credits
    4. Referral reward credits
    5. Top-up bonus credits
    6. Purchased credits (consumed last)

    This order ensures that bonus credits with expiration dates are used first, preserving the credits you paid for as long as possible.
  </Accordion>
</AccordionGroup>

## Credit Expiration

<Warning>
  Bonus credits have expiration dates and will automatically expire if unused. **Purchased credits never expire.**
</Warning>

Expiration rules vary by source:

| Source               | Expires? | Details                                       |
| -------------------- | -------- | --------------------------------------------- |
| Signup bonus         | ✅ Yes    | Validity period shown in the product          |
| Plan bonus           | ✅ Yes    | Typically valid within the subscription cycle |
| Referral rewards     | ✅ Yes    | Validity period shown in the product          |
| Top-up bonus portion | ✅ Yes    | Extra credits included in top-up packs        |
| Direct purchase      | ❌ No     | Base credits from top-up packs                |
| Team plan credits    | ✅ Yes    | Expires with the team license validity period |

<Tip>
  You can check the remaining balance and expiration dates for each credit type on your account's credits page.
</Tip>

## Team Credits

Team plan users share an **organization credit pool**:

* When the team is activated, credits are automatically injected into the organization pool
* All members' AI consumption is deducted from the same pool
* Administrators can view team usage reports to understand each member's consumption
* Administrators can purchase top-up packs for the team, with credits going directly into the organization pool

Team members' **personal credits are completely isolated** — leaving the team does not affect personal credits.

<Note>
  Team credit pool recharges are restricted to administrators. Regular members will receive a prompt when attempting to recharge.
</Note>

## Checking Your Credit Balance

You can check your current credits in the following places:

* **Avatar menu**: Click your avatar in the top-right corner to see a balance overview
* **Credits page**: View detailed credit breakdowns and consumption records in your account settings

The credit details show the source of each charge — which Expert was used, how many tokens were consumed, and how many credits were spent.
