OpenAI has released a new desktop app for macOS called Codex, which functions as an AI coding agent. The application is designed to move beyond conversational assistance by directly interacting with other programs on a user's computer, a step towards more autonomous, 'agentic' AI. This allows the AI to perform tasks on the developer's behalf, streamlining workflows.

The core feature, 'Work with Apps', enables Codex to read and understand the context of code within popular developer environments like VS Code, Xcode, and various text editors. By accessing code directly, the tool can provide more relevant assistance and reduce the need for developers to manually copy and paste information, integrating the AI more deeply into the coding process.
