Self-hosted proxy that farms ChatGPT image quotas across account pools

It turns ChatGPT’s browser-only image generation into a poolable, OpenAI-compatible API so you can self-host programmatic access to GPT-Image-2 and friends.

What it does

ChatGPT2API is a reverse-engineered proxy that exposes ChatGPT’s web-native image generation and editing—including GPT-Image-2 and Codex drawing—through standard OpenAI-compatible endpoints. It bundles a web-based drawing board, account-pool orchestration, and pluggable storage backends ranging from local JSON to PostgreSQL. Think of it as a translation layer between your apps and OpenAI’s browser-only features, with a built-in account rotator to keep requests flowing.

The interesting bit

The real machinery isn’t the API compatibility; it’s the account pool manager. The system imports credentials from CPA JSON dumps, sub2api servers, or raw access tokens, then automatically refreshes quotas, culls dead tokens, and retries through SOCKS proxies. It turns a handful of disposable ChatGPT accounts into a single logical image-generation endpoint, complete with progress tracking and server-side URL caching.

Key highlights

OpenAI-compatible endpoints for image generation, editing, and chat-formatted image requests (/v1/images/generations, /v1/images/edits, /v1/chat/completions for images)
Supports GPT-Image-2, Codex drawing (Plus/Team/Pro only), and several GPT-5 variants, plus exotic outputs like editable PPT and PSD files
Built-in web UI for drawing, editing, and multi-image composition with session history and lazy loading
Account pool automation: imports from CPA/sub2api, auto-refreshes quotas, evicts invalid tokens, and supports global proxy configuration
Pluggable storage backends: local JSON, SQLite, PostgreSQL, or even a private Git repository

Caveats

This is explicitly reverse-engineering; the README warns that accounts face “restricted, temporary or permanent ban” risks and prohibits commercial use
Text completion and streaming via /v1/complete and /v1/chat/completions are experimental and currently suffer from conversation repetition
Codex drawing support requires Plus/Team/Pro subscriptions and aliases a separate model (codex-gpt-image-2)

Verdict

Worth a look if you’re running a self-hosted AI stack and need programmatic access to ChatGPT’s web-only image tricks—provided you have spare accounts to burn. Everyone else should probably wait for an official API.
