# Choosing a Model

> What an AI 'model' is, and how to pick the right one — explained with a simple analogy.

## What is a "model"?

A **model** is the "brain" the AI uses to answer you. AI Suite offers several models, and you can switch between them.

Here's the easy way to think about it:

> Choosing a model is like choosing a **worker for a task**. Some workers are super fast and great for everyday jobs. Others are slower but think more carefully — perfect for hard problems. You pick the right one for what you need.

You don't need to understand the technology. You just need to know: **fast models for quick, simple things; smart models for hard, important things.**

## The simple rule

  <Card title="Pick a FAST model when..." icon="bolt">
    You want quick answers, simple writing, short summaries, or casual brainstorming. Great for everyday use.
  </Card>

  <Card title="Pick a SMART model when..." icon="brain">
    The task is tricky, detailed, or important — deep analysis, careful reasoning, or long, high-quality writing.
  </Card>

<Note>
  Smart models can take a little longer and may use more of your credits. That's normal — they're doing more thinking. See [Team & billing](/user-guide/team-and-billing) to understand credits.

## How to switch the model

<Steps>
  <Step title="Find the model picker">
    In Chat (and in apps and agents), there's a small dropdown showing the current model's name, usually near the message box or at the top of the conversation.

    </Frame>
  </Step>

  <Step title="Open the list">
    Click it. You'll see the models you can choose from, each with a short label.
  </Step>

  <Step title="Pick one">
    Click the model you want. Your next message will use it. You can change it again any time — even mid-conversation.
  </Step>
</Steps>

## Which one should I start with?

<Tip>
  If you're not sure, **use the default model**. It's chosen to work well for most everyday tasks. Only switch to a smarter model if an answer feels too shallow, or to a faster one if you just want quick replies.
</Tip>

## A quick way to compare

Not sure if a smarter model is worth it? Ask the same question with two different models and compare the answers. You'll quickly get a feel for which one suits your work.
