Use a Codex-style terminal agent with multiple cloud and local model providers.
Open Codex CLI forks the original Codex CLI while adding support for OpenAI, Gemini, OpenRouter, Ollama, and compatible endpoints. It uses the Chat Completions API so users can choose a broader range of models, then runs through a familiar terminal workflow after provider credentials are configured. The project is experimental and may change incompatibly.
