You keep the Claude Code agent workflow you like (file edits, terminal flow, approvals, MCP servers, skills) but the model answering is GPT-5.6, running on the ChatGPT subscription you already pay for instead of your Anthropic usage. One-line install. Plain claude stays completely stock. How it works claudecodex launches the real Claude Code UI, points it at a local Anthropic-compatible proxy on 127.0.0.1:18765, and the proxy forwards requests to GPT-5.6 via Codex auth on your ChatGPT subscription: Jump to: Install · Usage & model switching · Configuration · vs alternatives · Troubleshooting · FAQ: Claude Code without an Anthropic API key Demo (8× speed — watch the full demo video) --- Why run Claude Code with OpenAI models? - Claude Code UI + GPT models — the best agentic coding interface, driving OpenAI's strongest coding model (GPT-5.6 Sol at max reasoning effort). - Uses the ChatGPT subscription you already have — no pay-per-token API bills; requests go through Codex auth on your Plus/Pro plan. - Zero interference — a thin launcher that exec s claude with process-local environment variables. Your normal claude command, login, settings, and Anthropic models are untouched. -","default_branch":null,"files":null,"tree":[],"storefront":"/r/karem505","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/karem505/claudecodex/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
