# cancel\_generation

Cancel a feature's in-flight generation. The feature's status becomes `cancelled` and it unlocks for edits, deletes, and a fresh generation.

{% hint style="info" %}
Credits already consumed by the cancelled generation are not refunded — cancel early if the [status](/testvibe-api/api-reference/generation/get_generation_status.md) shows it heading the wrong way.
{% endhint %}
