# Tasks

## Use cases

* Tasks used for wrapping [**predictors**](/predictors.md). 
* Tasks include chains of actions that can be predefined to be executed before and after predictor execution. That can help with formattting of inputs and outputs of predictors. See:

[Predictors](/predictors.md)
{% endcontent-ref %}

{% content-ref url="/pages/AvAI7BBSttNLIBvNY0RS" %}
[Task](/tasks/task.md)
{% endcontent-ref %}

## Functionality

Task based on an [**Executable**](/core/executable.md) and introduces **preproccess** and **postprocess** chains of actions that are executed before and after predictor, respectively. See:
