Choose a model or agent

Last published : Nov 09, 2026
This guide shows you how to pick what the assistant runs on for a chat: a preset, an agent, or a specific model.
The button next to Add context (+), under the message box, shows your current choice. By default it shows Default.

Pick a preset

  1. Under the message box, select the current choice (for example, Default).
  2. Select one of the following:
    • Default: fast, cost-efficient, and recommended for everyday work.
    • Thinking: a higher-capability model for advanced, complex reasoning.
Your workspace decides which model backs each preset.

Pick an agent

An agent is the assistant with its own instructions, and sometimes its own model and permissions.
  1. Under the message box, select the current choice.
  2. Select an agent from one of these lists:
    • Provided by IT: agents your administrator assigns to your workspace.
    • My agents: agents you created or imported.
A list only appears when it has agents in it. To create an agent, select Build a new agent. For more information, see Create your own agents.

Pick a specific model

  1. In the message box, type /model. Select /model in the list that appears, and press Enter.
    The 🤖 Select Model dialog lists the models you can use, grouped by provider.
  2. Select a model. To find one, type in Search models....
The choice applies to this chat. If no models are listed, connect a model provider first. For more information, see Connect to a model provider.
You can also change the model in the chat's settings: at the top of the chat, select More actions (⋯), and then Chat settings. Leave Model as Default model to use the default.

Use a saved prompt with its own agent

A saved prompt can remember which agent to use. For more information, see Save prompts you reuse.
