pi-sticky-model

Keeps your model and thinking-level selections across /new, /resume, and /fork without mixing settings between sessions. Resets on Ctrl+C — no settings.json override needed.

What this is

Pi extension. When you switch models with /model or Ctrl+P, or change the thinking level, the selection sticks across /new, /resume, and /fork for the lifetime of the Pi process. Close Pi (Ctrl+C) and everything resets to your settings.json default.

For anyone tired of their model snapping back to the settings.json default every time they start a new conversation. Each session keeps its own model; a new or forked session inherits only from its predecessor.

Features

• Sticky model: /model selection persists across /new, /resume, /fork
• Sticky thinking: thinking level follows the selected model across /new, /resume, /fork
• Session-scoped: sessions keep separate model selections; Ctrl+C / process exit resets the current session
• Zero config: install and it works — no YAML, no JSON, no setup
• Reload-safe: /reload preserves your current model

Coexistence

This extension works alongside other model-switching extensions such as pi-weighted-model-router and pi-scheduled-router. Since all of them call pi.setModel(), the last one to fire wins. Control the priority by ordering your packages array in .pi/settings.json.

Install

Install the published npm package with Pi:

pi install npm:pi-sticky-model

Pin a specific version when you want reproducible installs:

pi install npm:pi-sticky-model@0.4.1

Install into the current project instead of your user Pi settings:

pi install npm:pi-sticky-model -l

Or install from GitHub:

pi install git:github.com/eiei114/pi-sticky-model

Try it without permanently installing:

pi -e npm:pi-sticky-model

Quick start

Try this package locally:

pi -e .

Then pick a model and thinking level, then run /new — both selections stay.
