Open Codex: An Offline Command-Line AI Assistant That Ensures Data Security

What is Open Codex?

Open Codex is an open-source command-line AI assistant created by the developer codingmoh, inspired by OpenAI’s Codex. Unlike the OpenAI Codex CLI, Open Codex focuses on local execution, aiming to run directly in the terminal without the need for an API key. It supports using local language models (such as phi-4-mini) for programming assistance.

Key Features

• Natural Language to Command Line: Users can input natural language commands (e.g., open-codex "list all folders") and receive corresponding shell command suggestions.

• Local Execution: Supports running on macOS, Linux, and Windows without relying on external APIs, ensuring data security.

• Execution Confirmation: Provides a confirmation mechanism before executing commands to prevent accidental actions.

• Lightweight Design: Developed in Python, it’s easy to install and suitable for daily use by developers.

Technical Principles

Open Codex uses the llama-cpp-python library to load the phi-4-mini model, performing inference locally. The model is optimized in GGUF format for efficient execution on local hardware. Unlike OpenAI Codex CLI, Open Codex avoids dependency on cloud-based APIs, focusing on optimizing and running local models.
