# Select the models for the Agent in Excel

In [GPT for Excel – Autosheet](https://autosheet.com/docs/gpt-for-excel), the Agent uses two types of models:

- **Agent models** handle chat messages, create formulas, and execute complex tasks by breaking them down into smaller tasks and delegating these to bulk models.
- **Bulk models** handle bulk tasks and web search tasks. The Agent uses bulk models when needed. The Agent can only use the bulk models you set in the [Autosheet dashboard](https://autosheet.com/docs/gpt-for-excel/agent/select-models#set-the-default-bulk-models).

## Recommended models

For information about recommended models for the Agent, see [Recommended models](https://autosheet.com/docs/resources/models/recommended-models).

## Select the Agent model

You can select the Agent model in the GPT for Excel – Autosheet sidebar. The models available depend on the models enabled for your space in the [Autosheet dashboard](https://autosheet.com/docs/admin/ai-configuration/manage-models#enable-and-disable-models).

In addition to built-in models, you can select [connected models](https://autosheet.com/docs/resources/guides/concepts#connected-model) in the model switcher. To make a connected model available, [set an API key](https://autosheet.com/docs/gpt-for-excel/setup/manage-models/manage-api-keys) or [set up an OpenAI-compatible API endpoint](https://autosheet.com/docs/gpt-for-excel/setup/manage-models/connect-to-api-endpoints).

1. In the sidebar, select **Agent**.
2. Open the model switcher and select the Agent model.

The Agent now uses the selected model.

## Set the default bulk models

**Prerequisites**

You are the owner or an admin of the space.

You can set two default models for bulk tasks:

- The **Default bulk model** is used by the Agent for bulk tasks. For new users in your space, this model is also selected by default for bulk tools and GPT functions.
- The **Default bulk model for web search** is used by the Agent for bulk tasks that require web search. This model is also used by the [**GPT_WEB**](https://autosheet.com/docs/gpt-for-excel/gpt-functions/reference#gpt_web-function) function.

You can only select [enabled bulk models](https://autosheet.com/docs/admin/ai-configuration/manage-models#enable-and-disable-models).

1. Sign in to the [Autosheet dashboard](https://dashboard.autosheet.com/) with your Microsoft or Google account.

2. In the sidebar, select **Bulk models**.

3. In the **Default bulk model** and **Default bulk model for web search** dropdowns, select the default bulk models for your space.
