# vastai update

Update the CLI to the latest version

## Usage

```bash theme={null}
vastai update [--check | --version VERSION]
```

## Options

<ParamField path="--check" type="boolean">
  only check for a newer version; exit 0 if current, 10 if an update is available
</ParamField>

<ParamField path="--version" type="string">
  install a specific version instead of the latest (also how you pin or roll back)
</ParamField>

## Description

Updates a CLI installed with the managed installer
(curl -fsSL [https://vast.ai/install.sh](https://vast.ai/install.sh) | bash). The new version is
installed into a fresh environment and verified before it is swapped
in, so an interrupted update never leaves a broken CLI. To roll back a
bad release, pin the previous one: vastai update --version 1.2.3
For pip installs, update with: pip install --upgrade vastai
