Open Codex is a command-line AI assistant that translates natural language into shell commands, inspired by OpenAI Codex. It targets developers and power users seeking a local, privacy-focused alternative to cloud-based AI coding assistants, enabling efficient terminal operations without API keys or external dependencies.

How It Works

The assistant leverages local, open-source language models, currently supporting phi-4-mini, to process natural language prompts and generate corresponding shell commands. This local-first approach ensures data privacy and offline functionality, while the one-shot interaction mode provides a direct natural language-to-command execution flow with user confirmation.

Quick Start & Requirements

• Install: brew tap codingmoh/open-codex && brew install open-codex (macOS), or pipx install open-codex (cross-platform).
• Prerequisites: Python.
• Setup: Minimal, as models run locally.
• Docs: https://github.com/codingmoh/open-codex

Highlighted Details

• Natural Language to Shell Command conversion.
• Works on macOS, Linux, and Windows.
• One-shot interaction mode with confirmation before execution.
• Colored terminal output for readability.
