# Pi

> Install Pi and connect its model catalog to the Phaseo Gateway.

## Set up with the Phaseo CLI

These production-ready commands require a Phaseo account; the CLI creates the dedicated gateway credential during sign-in and setup.

```bash theme={null}
phaseo login
phaseo pi
```

Setup installs Pi when needed and writes a managed provider extension to `~/.pi/agent/extensions/phaseo.ts`. The extension exposes every active Phaseo text model compatible with Chat Completions and resolves its dedicated API key from the Phaseo CLI at request time.

Choose an initial model or configure only one model when needed:

```bash theme={null}
phaseo pi --model anthropic/claude-sonnet-4.6
phaseo pi --catalog default
```

Use `--skip-install` when Pi is managed separately, and `--dry-run` to preview installation and file changes.

## Start and verify

```bash theme={null}
pi
```

Open `/model`, choose the `phaseo` provider, and send a small prompt. Remove only the managed extension and revoke its dedicated key with:

```bash theme={null}
phaseo integrations remove pi
```

## Manual credential access

The generated extension uses Pi's command-backed key syntax:

```text theme={null}
!phaseo integrations credential pi
```

No plaintext key is written to the extension.
