Open Codex is a fully open-source command-line AI assistant inspired by OpenAI Codex, supporting local language models like phi-4-mini.

No API key is required. Everything runs locally.

Supports:

  • One-shot mode: open-codex "list all folders" -> returns shell command
  • 🧠 Local-only execution using supported OS models (currently phi-4-mini)

✨ Features

  • Natural Language to Shell Command (via local models)
  • Works on macOS, Linux, and Windows (Python-based)
  • Confirmation before execution
  • Add to clipboard / abort / execute prompt
  • One-shot interaction mode (interactive and function-calling coming soon)
  • Colored terminal output for better readability

🧱 Future Plans

  • Interactive, context aware mode
  • Fancy TUI with textual or rich
  • Add support for additional OSS Models
  • Full interactive chat mode
  • Function-calling support
  • Voice input via Whisper
  • Command history and undo
  • Plugin system for workflows

📦 Installation

🔹 Option 1: Install via Homebrew (Recommended for MacOS)

brew tap codingmoh/open-codex
brew install open-codex

🔹 Option 2: Install via pipx (cross-platform)

pipx install open-codex

🔹 Option 3: Clone & Install locally

git clone https://github.com/codingmoh/open-codex.git
cd open_codex
pip install .

Once installed, you can use the open-codex CLI globally.


🚀 Usage
