# Optimize

In Optimize mode, Redefine optimizes your CI builds by selectively running tests that are related to code changes. This results in much quicker feedback from your CI processes and significantly better resource utilization. You can configure the desired [Configuration Parameters](/configuration/configuration-parameters.md#confidence) for the run; if it is not configured, Redefine will use the default confidence level.

```bash
redefine install --optimize --<testing_framework>
```

{% hint style="warning" %}

#### **Optimize mode requires feedback**

In order to use the Redefine Optimize mode, the tests need to receive feedback from a Discover mode run at least once a day. This is because Optimize mode relies on the feedback collected by the Discover mode to validate its predictions. Without regular feedback from Discover mode, Optimize mode may not perform optimally, which could result in inaccurate predictions.
