underclass pools a pile of Codex and Copilot subscriptions behind one OpenAI-compatible endpoint with sticky sessions
Geoffrey Huntley released underclass on 2026-09-20 (Rust, MIT, 136 stars same day), a local proxy exposing /v1/responses, /v1/chat/completions and /v1/models over N ChatGPT/Codex and M GitHub Copilot subscriptions added via OAuth device flow. Sessions are pinned to one account so the upstream prompt cache stays warm, quota-exhausted accounts leave rotation and return automatically when their window resets, and when everything is exhausted it fails fast with the earliest reset time instead of hanging. `underclass connect` writes the provider block into opencode's global config idempotently with backups.
