![pi-ultra: a solar pi core coordinating three subagents](https://raw.githubusercontent.com/filipores/pi-ultra/main/assets/pi-ultra-hero.png)

Codex-style Ultra mode for Pi: GPT-5.6 Sol at `max` reasoning plus proactive delegation through [`pi-subagents`](https://www.npmjs.com/package/pi-subagents).

## Install

```bash
pi install npm:pi-subagents
pi install npm:pi-ultra
```

Restart Pi, then enable Ultra:

```text
/ultra on
```

`/ultra` toggles the mode. `/ultra status` reports its state.

Ultra switches to `openai-codex/gpt-5.6-sol` (falling back to the direct OpenAI provider), selects `max`, and tells the parent agent to delegate independent work proactively. Changing the model or thinking level disables Ultra. The mode is session-local.

This does not invent an `ultra` API reasoning value: like Codex, the model request uses `max`; the additional behavior comes from the delegation policy and subagent tooling.
