Codex is designed as a cloud-native coding agent, differing from traditional coding tools by allowing users to interact with their codebase in a chat-like interface.

• It connects directly to GitHub repositories and supports multiple coding agents working in parallel.
• Each task operates in its own isolated environment, ensuring no conflicts arise.
• The interface promotes a collaborative coding experience, allowing for real-time feedback and adjustments.

2. Codex utilizes a custom model for enhanced coding performance.
