@async23/pi-codex-fast

A Pi extension that toggles OpenAI Codex Fast mode by setting service_tier to priority on Codex requests.

Install

pi install npm:@async23/pi-codex-fast

Restart Pi after installation, or run /reload in an existing session.

Usage

/fast    Toggle Fast mode on or off

The command does not accept arguments.

When enabled with an openai-codex model, the extension adds:

{
  "service_tier": "priority"
}

Fast mode is stored globally in codex-fast.json under Pi's agent configuration directory (normally ~/.pi/agent/codex-fast.json). It persists across projects, sessions, reloads, resumes, and Pi restarts.

Each running Pi instance reads the global state when its session starts. /fast updates the current instance and writes the new global state. Other Pi instances that are already running keep their in-memory state until their session restarts, /reload runs, or Pi restarts.

If another provider is selected, the footer shows a dim, struck-through fast; Fast mode takes effect again after selecting an openai-codex model.

Usage warning

Fast mode consumes Codex credits at a higher rate than Standard mode.
