Pi

A terminal coding-agent harness built for extensibility.

Pi is a terminal coding agent with themes, extensions, sessions, tools, and multiple model providers. Subscription authentication is built into its provider flow rather than requiring a community proxy.

What you can do

Codex-model requests in Pi use the allowance attached to the authenticated ChatGPT subscription.

Good to know

Pi does not document automatic switching to a separately billed provider at the plan limit.

ChatGPT limits
Model availability and plan limits are controlled by OpenAI. API-key providers remain separate.
Possible extra cost
Another provider can be selected manually and may require its own key or subscription.
