@ryan_nookpi/pi-extension-codex-large-context

This extension raises the pi context window metadata for newer OpenAI Codex models.

It is intended for gpt-5.4 and gpt-5.5 model IDs when pi reports a smaller context window than the model can actually handle.

Install

pi install npm:@ryan_nookpi/pi-extension-codex-large-context

Usage

Large context mode is ON by default.

/codex-large-context on
/codex-large-context off
/codex-large-context status

Running /codex-large-context with no argument shows the current status.

What it does

• Watches session_start and model_select events while enabled.
• If the active model ID starts with gpt-5.4 or gpt-5.5, sets its context window to 922000 tokens.
• Stores the on/off setting locally so it persists across sessions.
• Shows a small notification when the context window is updated in the interactive UI.

Notes

• This only changes pi's local model metadata for the active session/model selection.
• It does not change API limits on the provider side.
• If pi already reports a context window of 922000 tokens or more, it leaves the model unchanged.
• Turning the feature off prevents future context-window adjustments; it does not restore a model that was already adjusted earlier in the session.
