# pi-codex-5.5

A [pi](https://shittycodingagent.ai) extension that adds a `gpt-5.5` model to the existing built-in `openai-codex` provider.

> This extension is just a quick win. Official `pi.dev` support for `openai-codex/gpt-5.5` should land soon.

## What it does

- reuses the built-in `openai-codex` provider
- preserves the existing OpenAI Codex OAuth login flow
- keeps all currently built-in `openai-codex` models
- adds or overrides `gpt-5.5`

`gpt-5.5` is derived from `gpt-5.4` with these changes:

- **context window:** `1,000,000`
- **cost:** doubled from `gpt-5.4`

## Install

Local path install:

```bash
pi install npm:pi-codex-5.5
```

## Auth

Log in with the normal Codex provider if needed:

```text
/login openai-codex
```

## Result

After install/reload, select:

- provider: `openai-codex`
- model: `gpt-5.5`
