Run local LLM in ChatGPT Desktop app with opencodex alone

The open-source tool opencodex (MIT license) works as a local proxy and replaces the base URL in ~/.codex/config.toml, forcing the ChatGPT Desktop app to use third-party and local models. It supports Ollama, vLLM, LM Studio, and over 40 providers, including Anthropic, Gemini, DeepSeek, and Qwen.
