claudeg

Run Claude Code through your ChatGPT subscription.

Install

Requires Claude Code first.

macOS / Linux

curl -fsSL https://claudeg.org/install.sh | sh

Windows / PowerShell

iwr -useb https://claudeg.org/install.ps1 | iex

Log in

Opens your browser for ChatGPT OAuth PKCE. Tokens cache at auth.json (mode 0600 on Unix). claudeg auto-detects your tier (Plus / Pro / Business / Enterprise) from the OAuth JWT and picks the right ChatGPT model for each Claude model.

claudeg login

Use

claudeg                       # interactive session via your ChatGPT subscription
claudeg "<prompt>"            # one-shot
claudeg --resume <id>         # resume a saved Claude Code session
claudeg --continue            # continue the most recent session
claudeg whoami                # show tier + model mapping
claudeg logout                # forget cached credentials

Any flag that isn't a claudeg subcommand is forwarded verbatim to claude, so claudeg --resume <id>, claudeg -p "prompt", claudeg --model claude-haiku-4-5 "..." and friends all work the same as their claude counterparts.
