# @dust Agent

## What is `@dust` and how to use it?

`@dust` is the general-purpose agent set up by default in every workspace. Mention it with `@dust` in the composer to ask a question, or simply send a message without mentioning any agent: Dust routes unmentioned messages to the workspace's default agent, which is `@dust` unless an admin has configured a different one.

`@dust` answers using all the Company Data your account has access to: the connected data sources, tools, and knowledge integrated into your workspace.

<Info>
  Default agents like `@dust` are provided by Dust and can't be edited through the Agent Builder. Workspace admins can only enable or disable them; their instructions and tools aren't customizable.

## When to use `@dust`

Use `@dust` as your starting point for:

* General questions about your company's internal documentation and connected data sources.
* Quick, single-turn requests that don't need a dedicated custom agent.
* Getting started with Dust before building specialized agents for your team.

For questions that need extended, multi-step research across many sources, mention [`@deep-dive`](/docs/user-documentation/agents/default-agents/deep-dive-agent) instead.

## Choosing a model

By default, `@dust` runs on the auto-model level configured for your workspace. You can pick a different model for a single conversation from the model picker in the composer, without editing the agent. See [Auto models and the model picker](/docs/user-documentation/agents/model-selection) for details.

## Admin control

Workspace admins can deactivate `@dust`, like any other default agent, from workspace settings. If your workspace has `@dust` disabled, the model picker and your other agents (including custom agents) remain available; an admin can re-enable `@dust` at any time.
