@howaboua/pi-gpt-switcher

Pi extension adding quick model commands:

Command	Model
/sol [reasoning]	openai-codex/gpt-5.6-sol
/terra [reasoning]	openai-codex/gpt-5.6-terra
/luna [reasoning]	openai-codex/gpt-5.6-luna
/astra [reasoning]	openai-codex/gpt-6-astra

An explicit reasoning argument overrides the configured default. Valid arguments are off, minimal, low, medium, high, xhigh, and max; for example, /luna low.

Defaults

On first load, the extension creates pi-gpt-switcher.json in Pi's global agent directory:

{
  "sol": { "contextWindow": 272000, "reasoning": "high" },
  "terra": { "contextWindow": 872000, "reasoning": "high" },
  "luna": { "contextWindow": 472000, "reasoning": "xhigh" },
  "astra": { "contextWindow": 272000, "reasoning": "low" }
}

Edit the file to change a shortcut's session context window or default reasoning. Changes apply on the next shortcut invocation and do not alter the provider catalogue. Context windows may be lowered to 128k but not raised above the shortcut's shipped limit.

Existing config files need no migration: omitted shortcuts use their shipped defaults.

Install

pi install npm:@howaboua/pi-gpt-switcher

Try it for one session:

pi -e npm:@howaboua/pi-gpt-switcher

How it works

The commands use Pi's model registry and normal provider authentication. If a model is unavailable or the OpenAI Codex credentials are missing, the command reports that instead of changing the current model.

Pi clamps the requested reasoning level automatically if the selected model supports fewer levels.

Local development

Load the checkout directly:

pi -e ./index.ts
