ChatGPT Subscription Routing

Route requests through your ChatGPT Plus/Pro subscription using Plano. Uses the OpenAI Responses API under the hood, targeting chatgpt.com/backend-api/codex/responses.

Setup

1. Authenticate with ChatGPT

planoai chatgpt login

This opens a device code flow — visit the URL shown and enter the code. Tokens are saved to ~/.plano/chatgpt/auth.json.

2. Start Plano

planoai up config.yaml

3. Send a request

curl http://localhost:12000/v1/responses \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-5.2",
    "input": "Hello, what model are you?"
  }'

Or use the test script:

bash test_chatgpt.sh

How it works

chatgpt/gpt-5.2 in the config tells Plano to use the ChatGPT subscription provider
Plano reads OAuth tokens from ~/.plano/chatgpt/auth.json (auto-refreshes if expired)
Requests are proxied to https://chatgpt.com/backend-api/codex/responses with the required headers:
- Authorization: Bearer <access_token>
- ChatGPT-Account-Id: <account_id>
- originator: codex_cli_rs
- session_id: <uuid>

Available models

chatgpt/gpt-5.4
chatgpt/gpt-5.3-codex
chatgpt/gpt-5.2

Managing credentials

planoai chatgpt status   # Check auth status
planoai chatgpt logout   # Remove stored credentials
