## What it is
An OpenCode plugin that authenticates via OpenAI's official ChatGPT OAuth flow, letting users with ChatGPT Plus/Pro subscriptions access GPT-5.x and Codex models instead of paying for API credits. It installs model presets, handles token refresh, and supports both modern and legacy OpenCode versions.

## Use cases
- use my ChatGPT Plus subscription with opencode instead of API credits
- authenticate opencode with ChatGPT OAuth
- set up GPT-5 Codex models in opencode with one command
- configure codex model presets and reasoning variants for opencode
- fix token refresh and usage-aware errors for ChatGPT auth in opencode
- install opencode auth plugin over SSH or WSL with manual URL paste

## When to choose
- you have a personal ChatGPT Plus/Pro subscription and use OpenCode for coding assistance
- you want GPT-5.x/Codex model presets configured automatically without manual JSON editing
- you need automatic token refresh and usage-aware error handling for the Codex backend

## When to avoid
- you need production, commercial, or multi-user API access - use the OpenAI Platform API instead
- you don't use OpenCode as your coding assistant
- you want to use models outside the GPT-5.x/Codex families
