# Configuring your devbox architecture

> Configuring the architecture on launched devboxes

<Tip>Start with the [Runloop Quickstart](/docs/tutorials/quickstart) to use the examples below.</Tip>

### Standard architecture

Runloop Devboxes default to `x86_64` architecture.

You can specify either `x86_64` or `arm64` explictly to choose the architecture for launched devboxes.

<CodeGroup>
  ```python Python theme={null}
  devbox = await runloop.devbox.create(
    name="architecture-box",
    launch_parameters={"architecture": "x86_64"},
  )
  ```

  ```typescript TypeScript theme={null}
  const dbx = await runloop.devbox.create({
    name: 'architecture-box',
    launchParameters: { architecture: 'x86_64' },
  });
  ```
</CodeGroup>

### Incorrect usage: Mixing architectures between blueprints and devboxes

Blueprints created on `x86_64` will not work on `arm64` devboxes and
vice-versa.  If you do not specify an architecture for your Blueprint,
Runloop will default to `x86_64`.
