Persist Model

Persist Model is a Pi extension for controlling how model and reasoning-level settings are applied.

Use it to keep changes temporary for the current session, save them for a specific workspace, or apply them globally.

pi install npm:pi-persist-model
/persist-model   ← opens TUI

The problem

Pi stores model and reasoning defaults in ~/.pi/agent/settings.json. Every time you switch model or reasoning level, Pi writes those changes to the global config — so a quick "let me try GPT-5 for this one question" silently becomes the default for every future session and every project.

Persist Model intercepts those changes and keeps them scoped to your chosen policy: session-only, per-workspace, or global.

No project .pi/ folders. All state in ~/.pi/persist-model/config.json.

Scopes
