# Codex

> Run Codex through Avibe — from the browser Workbench or any chat app.

# Codex

Codex is the OpenAI coding-agent path for Avibe users.

## Install

```bash theme={null}
npm install -g @openai/codex
```

Verify:

```bash theme={null}
codex --version
```

## Models & reasoning effort

Codex runs on your own OpenAI access. In the [Workbench](/concepts/workbench) you pick the model and the **reasoning effort** per agent — lower for quick edits, higher for hard problems — the same knobs you'd set on the CLI, surfaced where you route work. Keep credentials local.

## Configure in Avibe

In the setup wizard:

1. Enable Codex.
2. Confirm the `codex` CLI path.
3. Choose a default working directory.
4. Route one or more chat channels to Codex.

## Best for

Quick experiments and prototypes, and tasks where you want to dial reasoning effort up or down. Route your `#prototypes` or experiment channels here — see [Thread sessions](/concepts/thread-sessions) for routing.

## Usage notes

* Keep OpenAI credentials local.
* Use one chat thread per task.
* Keep large tasks scoped with clear acceptance criteria.
