OpenAI Ships Codex 'SuperApp' Update — Computer Use, Image Gen, Memory, and Plugins for macOS and Windows

OpenAI Blog·high signal

OpenAI's updated Codex app adds GPT-5.4's native computer-use capabilities, in-app browsing, image generation, persistent memory, and a plugin marketplace to both macOS and Windows. This pushes Codex beyond code-only workflows into mixed browser-plus-code tasks, UI inspection, and workflow validation. Marketplace plugins can be installed from GitHub URLs, local directories, or direct marketplace.json links.
