# Model

> The brain the Digital Worker thinks and answers with

Every Digital Worker runs on a language model. The model decides how deeply the Digital Worker can reason, how much context it holds and how much each turn costs.

## What the Model screen shows

* **Connected** - the model the Digital Worker is running on, with figures such as context window and maximum output length.
* **Workspace models** - the list of models the workspace allows. Click **Use** on a card to switch the Digital Worker over.

Each card carries capability labels - **Reasoning** (for multi-step thinking) or **Vision** (can read images), for example - so you can tell at a glance which model suits the job.

## Choosing the right one

| What the Digital Worker does | Favour |
| - | - |
| FAQ answers, quick lookups, high volume | A small, fast model |
| Analysis, planning, multi-step work | A model strong at reasoning |
| Long documents, lots of context | A model with a large context window |
| Images, screenshots, scanned documents | A model with the vision label |

> [!TIP]
>
> After switching models, run **Test chat** through a few familiar scenarios. The same Instructions can read very differently to two different models.

## How to switch a Digital Worker's model

**1. Open the Model section**

On the Digital Worker page, go to the Digital Worker builder tab. The Configuration column on the right shows the model the Digital Worker is running on.

**2. Look at the alternatives**

Click the Model box for a short list, or click View all models to open the workspace's full catalogue with figures to compare - context window, output length and capability labels.

**3. Click Use**

Click Use on the model you want. The Digital Worker switches over immediately - there is nothing else to save.

> [!NOTE]
>
> There is no add, remove or enable/disable for models at the Digital Worker level. The catalogue is a fixed workspace list (Resources > Models), and a Digital Worker always runs exactly one model at a time - so switching is the only action there is.
