    Use Cases & Benefits

    • OpenAI Codex CLI is a lightweight Rust-based coding agent that runs locally in the terminal, enabling code generation, refactoring, and automation.
    • Key features include sandboxed execution, multiple autonomy levels, integration with ChatGPT and OpenAI API, and support for Open Source models and MCP tools.
