**Generate images with your ChatGPT subscription — no `OPENAI_API_KEY`.**

A tiny zero-dependency Python CLI (and AI-agent skill): one file, stdlib only. Works on a **free ChatGPT account** too — the default backend just drives the normal ChatGPT web chat, where even free-tier users get image generation.

git clone https://github.com/leeguooooo/chatgpt-imagegen
sudo install chatgpt-imagegen/chatgpt-imagegen /usr/local/bin/chatgpt-imagegen

You also need **one backend** — `web` (default, drives your logged-in Chrome, spends no Codex-usage) or `codex` (headless fallback). `chatgpt-imagegen doctor` shows what's ready. → **[Backends & troubleshooting](https://drawstyle.leeguoo.com/en/docs/backends)**

Got a **Gemini** subscription too? Two more backends use it instead of OpenAI: `--backend gemini` (drives a logged-in `gemini.google.com` Chrome) and `--backend agy` (the Antigravity CLI, headless). They bill **separate quotas** from each other, so either can cover for the other. Neither is ever chosen automatically — ask by name. Pin the subscribed Chrome profile with `--gemini-profile`, since most profiles are signe
