About this plugin

Many users wish to leverage the powerful ChatGPT Codex models within DeepSeek Harness without the hassle of manual configuration or local callback servers. The DeepSeek Harness OpenAI Codex plugin is designed to solve this by seamlessly integrating a ChatGPT Plus or Pro subscription as an available LLM provider.

The plugin introduces a secure device-code OAuth login flow, allowing users to authenticate via a browser while managing sessions through Harness's /codex CLI or Web interface. It automatically handles token refreshes to ensure continuous availability and visually displays Codex usage limits in the Web settings, making quota monitoring effortless.

This feature is ideal for developers and engineers already using DeepSeek Harness who possess a ChatGPT Plus or Pro subscription with Codex access. Whether you interact via the command line or the Web UI, the plugin streamlines the onboarding process for Codex models, letting you focus on code generation and intelligent interaction while handling the underlying token management automatically.
