README

pi-codex-5.5

A pi extension that adds a gpt-5.5 model to the existing built-in openai-codex provider.

This extension is just a quick win. Official pi.dev support for openai-codex/gpt-5.5 should land soon.

What it does

  • reuses the built-in openai-codex provider
  • preserves the existing OpenAI Codex OAuth login flow
  • keeps all currently built-in openai-codex models
  • adds or overrides gpt-5.5

gpt-5.5 is derived from gpt-5.4 with these changes:

  • context window: 1,000,000
  • cost: doubled from gpt-5.4

Install

Local path install:

pi install npm:pi-codex-5.5

Auth

Log in with the normal Codex provider if needed:

/login openai-codex

Result

After install/reload, select:

  • provider: openai-codex
  • model: gpt-5.5
