dsh-llm-codex-oauth

The dsh-llm-codex-oauth plugin addresses a key challenge: how to leverage existing ChatGPT/Codex subscriptions (such as Plus, Pro, Business, or Edu) within the DeepSeek Harness (dsh) environment. Many users seek to integrate OpenAI's paid model capabilities seamlessly into dsh's inference workflow without switching tools, but official direct interfaces are unavailable. Through a secure OAuth device code login flow, this plugin converts a user's ChatGPT subscription quota into a callable model provider for dsh, enabling unified access to advanced language models in local or development settings.

Its core capabilities lie in seamless integration and secure credential management. Users need only complete one OAuth login in the dsh settings page to add subscription models (e.g., GPT-5.x series) as dsh model options, with support for image inputs and multi-turn conversations, while automatically handling token refresh and error retries. All sensitive information remains secure locally, and the plugin adheres to a minimalist design, focusing on model integration rather than image generation or other extensions.

This plugin is ideal for developers, researchers, or advanced users who own a ChatGPT/Codex subscription and wish to conduct efficient model inference within DeepSeek Harness. It is especially suited for scenarios requiring unified workflows to test or deploy multiple models, emphasizing code security reviews, and accepting the risks of using unofficial APIs. If you use dsh for AI-assisted development and want to streamline subscription model access, this plugin can significantly enhance your productivity.
