# Choose your generative model

> Pick the right model for speed, quality, vision, and privacy in Alter

Use this when you want better results for a specific task, not just the default model.

## Quick model selection in chat

<Steps>
  <Step title="Open model picker">
    In Alter, type `/` to open the model list.
  </Step>

  <Step title="Choose the model">
    Select a model based on your task type, then send your prompt.
  </Step>

  <Step title="Favorite frequent models">
    Click the star next to a model to pin it for faster access.
  </Step>
</Steps>

## Set your default model

Use `/` to pick a model. The selected model becomes your default model immediately and stays active until you choose another one.

## Practical model choices

* Use a fast model for short daily tasks.
* Use a stronger reasoning model for complex planning or coding.
* Use a vision-capable model when you add images.
* Use local or custom models when privacy requirements are stricter.

<Tip>
  If you are unsure, start with `/best`, then switch only when you need lower latency or a specific capability.
