GPT (Codex CLI) is a powerful coding agent from OpenAI, designed to run directly in your terminal. It allows developers to inspect code, make changes, run commands, and automate repeatable tasks without leaving the command line interface. This tool integrates with various large language models, including GPT-5.3-Codex, and can be installed via `npm` or Homebrew. It offers different profiles (e.g., 'balanced', 'safe') to control approval workflows and sandbox access, ensuring secure and efficient local development. The CLI is a robust alternative to cloud-based agents, providing direct control over your codebase and supporting scripting for non-interactive automation.
