# How do Credits work?
We introduced the credits system after our GPU cluster bill came back a few digits longer than expected. Credits allow you to continually run transcription and custom metadata jobs across your assets
{% hint style="info" %}
Enterprise customers are able to run transcription and metadata jobs for free as a part of the migration process
{% endhint %}
**The current rate for metadata is:**
* **5 credits per attribute per asset**
* **4 credits/minute for the nano model (96% accurate, 8 languages)**
* **8 credits/minute for the best model (99% accurate, 26+ languages)**
Credits can be purchased in bulk in different tiers from your workspace Settings/Usage page. The transcription model quality can be changed from your workspace settings.
### Example
This asset includes 3 attributes, 1 custom metadata attribute and 2 AI metadata attributes. Generating the 2 AI attributes incurred 10 credits (5 per AI attribute). Manual custom metadata attributes are free and do not incur credits. 10 credits will be used for every asset in this drive as AI metadata attributes are applied to every asset in a drive.
If an AI does not produce an output for an asset, it will not incur a credit.
